3 1 Executive Summary Converged networks have been evolving since their initial deployments, with simple Voice over IP transport services giving way to next-generation networks supporting intelligent multimedia communications. The focus of the enterprise has evolved as well, moving from simple cost savings towards embedding communications into business processes, improving worker productivity, and enhancing customer interactions. Yet even the most advanced enterprises have typically limited their IP Telephony deployments to their own intranets, and not across the public network. integration challenges have prevented the full realization of end-to-end IP telephony communications. However, solutions are emerging that will reduce these challenges, and at the same time deliver an additional wave of financial and operational benefits. New solutions are possible due to a number of factors including: IP Telephony is reaching a critical mass within enterprise networks. Service Providers are leveraging their mature IP backbones to offer voice trunking services to enterprises. Growing acceptance of Session Initiation Protocol () by both Service Providers and Enterprises as the primary protocol for multi-vendor interoperability. Session Initiation Protocol () is an open industry multi-media signaling standard loosely modeled after existing, mature standards like SMTP and HTTP. The openness of allows carrier voice equipment to interoperate with enterprise voice equipment over an IP network. The logical voice channel established between them is known as a Trunk. Trunks enable enterprises to create a single, pure IP connection to carrier clouds. Trunks offer both hard dollar and productivity improvements including: Elimination of the need for and cost of separate & data circuits at the enterprise. Reduced cost of communications between an enterprise and its partners and suppliers. Support for multiple forms of real-time communication including voice, video, and instant messaging, along with the benefits of user-based presence. Reduced toll charges from origination/termination services to the for external long-distance and local access calls. Reduced hardware costs. Avaya is leading the transformation of enterprise communications applications to take full advantage of the economic rewards promised from networking. Avaya has dramatically expanded its offering of enabled platforms and applications and has established an aggressive interoperability program to ensure remains open among a large array of application and service providers. Introduction For years, converged network visionaries have been promising a single communications circuit to connect the enterprise to a service provider network. Voice, data, , video, and other services would traverse this single integrated link, efficiently connecting the enterprise to its remote sites, customers, and partners. Incremental steps toward this unified network have been taken in enterprise and service provider networks. Many years ago, carriers began routing voice calls over their private IP networks, to lower costs and improve network efficiencies. Meanwhile, enterprises were connecting IP-PBXs between sites over private IP networks to save toll costs. More recently, enterprises have begun to flatten, consolidate, and extend their communication networks by deploying remote IP-connected gateways off of central servers to reduce operating costs, leverage centralized applications, and enable management of multiple sites as a single system.

4 2 But the vision of a single circuit to the cloud proved elusive... until now. Several critical factors have converged to bring Session Initiation Protocol () networking to the Enterprise market. Enterprise penetration of IP telephony has reached a critical mass. According to Nemertes research, over 71% of IT professionals surveyed now have IP telephony deployed in their network. In many cases, VoIP connectivity using trunking can be readily introduced into these networks with minimal hardware and cost impact. This provides a ready market of significant size for service provider trunking services. 1 Enterprises are looking to expand the value of their IP telephony networks by extending the cost and deployment benefits to the partner/supplier eco-system side of their networks. Service Providers, looking for new revenue streams and competitive differentiators, are adapting their mature wholesale IP peering services into retail trunking services. Session border elements for have become widely available, robust, and rich with the necessary security and management features. has reached a required maturity level and is rapidly gaining acceptance as the preferred signaling protocol for real-time communications requiring multi-vendor interoperability. This paper will explore the emergence of Networking and what it can mean for achieving new network efficiencies and application deployment. It will also illustrate how customers can benefit now from the deployment of trunks within their enterprise networks and explore how Avaya is supporting the effective deployment of through its Converged Communications Server capabilities and its support of open interoperability for networking and applications. Networking Across the WAN The Session Initiation Protocol () is an open industry standard built on top of mature Internet standards, like TCP/IP and DNS. s openness allows carrier voice equipment to interoperate with enterprise voice equipment over an IP network. The logical voice channel established between them is known as a Trunk. Trunks enable enterprises to create a single, pure IP connection to carrier clouds. An Enterprise Proxy peers with a Carrier Proxy, with the appropriate federations and security protections between them. The IP network continues to carry , Internet, and other corporate data traffic as it does today, and voice is simply layered on top of the network as another IP application. sets up and tears down voice calls to and from the enterprise over this IP data network. Intra-enterprise or on-net calls are typically sent over the enterprise s private IP or MPLS backbone, while off-net calls to the are handed off to the Service Provider via. These off-net calls then ride the carrier IP network until the last mile, where a gateway converts VoIP to TDM for calls to parties. Enterprises may also have the option of having on-net calls between facilities or locations traverse a Service Provider s VoIP backbone, which is typically dedicated to voice so that voice quality can be guaranteed. Trunks are transparent to the underlying data link topology. Since is an application layer protocol, trunks can ride over any suitable Layer 2 protocol, such as MPLS or Metro Ethernet.

5 3 Trunks Offer Cost Savings and Productivity Advantages Local Loop at $200-$500/month /DS-1 card at $3-$5K Local DIDs Toll Free 800 Usage charge ~$0.029+/minute Long Distance Local DID Local Loop Elimination of separate and data circuits at all enterprise locations VoIP Today Trunking PBX Headquarters IP Network Analog or PBX Branch Location Reduced external communication costs between an enterprise and its partners, suppliers, and customers Toll Free 800 Long Distance Local DIDs Usage charge ~20% less Unification of multiple forms of real-time communications PBX Headquarters Carrier Network PBX Branch Location Figure 1: Trunking Changes How Enterprises Connect With Carriers The introduction of trunks can produce important new value to enterprises. In some cases, unique features like local number portability (LNP) are available. Calls destined for a local DID can be automatically re-routed over the network to a central location such as a data center. This offers tremendous flexibility for contact center calls, among others. For instance, if a call is destined for a number associated with a remote sales branch, it can be re-routed to a central contact center agent, who could handle the call more efficiently and cost-effectively. If the caller needs to speak with someone directly at the branch, the agent can transfer the call to the branch using the enterprise WAN or a Service Provider network, at a much lower rate than if the transfer were made over the. Trunks offer both hard dollar and productivity improvements. A single link can support intra-enterprise connectivity and provide external long-distance and local voice access to the through the Service Provider network. This results in hard dollar savings to enterprises as monthly recurring costs are lowered by eliminating all of the traditional circuits into the central PBX and by reducing the number of local trunks terminated by enterprise gateways at remote offices. Off-net calls to numbers are carried on the Service Provider IP backbone to the closest gateway, where the call is converted to TDM for the last mile. Per-minute toll charges on these calls are typically greatly reduced (approximately 20% less than similarly negotiated toll rates), since less tariffs are applied and fewer numbers of carriers have to handle the call. The productivity and application benefits of are becoming increasingly compelling. Full networking, including the last mile connectivity of Trunking, expands the flexibility and applications richness of roaming enterprise users back to communications services in the core of their corporate network. As cell phones and other mobile devices become -enabled, networking will provide the mobile user with connectivity to presence, Instant Messaging, and other application services. This will enable a mobile user with his cell phone to look present to a desk worker back at the office so the on-site user can IM or pushto-talk with the mobile worker.

6 4 Service Providers Are Rebuilding Their Networks Around A diverse group of Service Providers are building network capabilities including mobile network operators, large Inter-Exchange Carriers, Competitive Local Exchange Carriers, large cable operators, and Tier 2 service providers. While initial offerings have tended to highlight new services, many carriers have gone beyond offering as a service by standardizing on it as the core signaling protocol within their networks. The two primary standards bodies (3GPP/3GPP2) that are defining specifications for third generation (3G) mobile systems have both specified as the primary signaling protocol for IP-based voice and multimedia. Many new services being introduced on existing 2.5G wireless networks are already based on. Traditional carriers are also beginning to deploy at the core of their network, using border elements such as signaling and media gateways to provide interworking with other protocols. Because supports essentially any type of real-time communications, resources for security, authentication, billing, routing intelligence, etc. can be easily applied to any service the carrier develops. As a peer-to-peer protocol, much of the intelligence required for adding new services can be distributed as modular components that can be easily added via application servers without having to make any changes to the underlying infrastructure. Service Providers Are Implementing Services Standardized interworking with a variety of other protocols Media Servers Application Servers Signaling Call Control Core Network Functions Signaling Media SS7 Routing Proxy SS7/IP Signaling Gateway Service Provider Network Signaling Media SS7 /TDM Border Gateway Customer Networks TDM Customer Network Allows resources to be easily leveraged across multiple services Media Signaling Routing Proxy Signaling Signaling Media Routing Proxy Signaling H.323 Media /H.323 Border Gateway Customer Network Modular environment speeds new service deployment Peer Network Border Element Media Routing Proxy Signaling Media Edge Proxy Signaling Media Customer Network Figure 2: Service Provider Network With, carriers are rapidly replacing their hardware-based TDM networks with a software-centric model that provides greater flexibility, reduces costs, and provides a more open architecture. As Figure 2 shows, border gateway elements are required today at the edge of the network to interface with most enterprise networks. These border gateways represent a capital and operating cost to translate other protocols to a common base. For the carrier, offering trunk services allows them to avoid the border gateway complexity altogether. These cost savings can be passed to the enterprise in the form of very competitive pricing for services.

7 5 Exploring the Benefits of Networking for the Enterprise As Service Providers re-architect their networks using, enterprises are beginning to discover the substantial benefits of enabling their corporate networks to incorporate. Among the most fundamental impacts of will be improving the efficiency of communications between enterprises and their partners, suppliers, and customers. The initial wave of VoIP benefits has been primarily limited to intra-enterprise communications. Communications between enterprises, even those that are VoIPenabled, still require a circuit-switched hand-off that impacts voice quality, adds complexity, and introduces unnecessary expense through intermediate carriers. This concept of Islands of VoIP Connectivity, in which VoIP traffic is possible within individual enterprise islands but voice communication between islands requires traversal through the, are due primarily to signaling incompatibility between systems and the lack of a common source of directory information. 2 and universal directory solutions such as Electronic Number Mapping (ENUM) promise to address these issues. To demonstrate how these technologies can solve the current networking bottleneck, a manufacturing enterprise example can be used to illustrate the four phases of networking transformation. The manufacturing company has developed an extensive supply-chain ecosystem with a number of partners and suppliers. Both the manufacturer and its partners/suppliers require regular real-time communications between each location within the ecosystem. Phase 1: Traditional Networking Model Using The requirement for regular real-time communications within the eco-system is initially met through a separation of voice and data networking. Data inter-connection between members of the ecosystem leverages the Internet and is secured through IP VPN connections. Voice inter-connection, including intra-enterprise, is achieved through the. This traditional networking configuration separates voice and data traffic, as illustrated in Figure 3. It produces high quality voice capabilities, but does so at a high cost. With separate and data networks, hardware infrastructure and management costs are duplicated. Since all voice calls travel through the, pricing is based upon duration, geographic distance, and rigid tariff structures of the.

8 6 Traditional Voice Network Drawbacks Parallel TDM/IP infrastructure costs TDM connections Toll/tariff charges Wasted bandwidth Inter-Enterprise Voice via Phones PBX Long Distance PBX LAN Data Data IP WAN IP WAN Data Partner Supplier Sites Local Analog Analog Phones LAN Data Branch Sites Intra-Enterprise Voice via Figure 3: Traditional Voice Network Architecture Phase 2: Transition to IP Telephony Today IP telephony technology today addresses some of the cost and efficiency issues of traditional dual networks. Figure 4 depicts the consolidation of voice and data network traffic across an enterprise IP WAN for both the manufacturing firm and its suppliers/partners.

9 7 Telephony Server Limitations of Today s IP Trunking Islands of VoIP Connectivity connected via Residual toll/tariff charges to other Islands ice via Inter-Enterprise Vo Phones Gateway Long Distance LAN Data/VoIP Data/VoIP IP WAN IP WAN Data/VoIP Partner Supplier Sites Local Analog Analog Gateway Phones LAN Data/VoIP Branch Sites Telephony Server Intra-Enterprise Voice via VoIP Figure 4: IP Telephony Trunking Today Note that from a physical connectivity standpoint, almost nothing has changed! In this example the enterprise and its suppliers have each migrated their internal voice communication over to IP by routing intra-company voice traffic over a private WAN or managed MPLS network, allowing them to reduce their intra-company toll and tariff charges. Consolidation of voice and data over IP further reduces overall network costs by increasing the enterprise s utilization of available network bandwidth. The deployment of a VoIP WAN makes new applications such as off-shore outsourcing of call centers cost effective to implement since the WAN can be extended to any global location. Yet the deployment of IP Telephony over an enterprise WAN has not yet fully optimized the full potential of IP networking for communications between an enterprise and its eco-system of partners/suppliers/customers. This is due primarily to the complexity of inter-connecting the different systems often in place between enterprises and because of the lack of a universal directory service to map phone numbers to the IP addresses of telephony servers. Most external enterprise communications still require a circuit-switched hand-off; enterprises must continue to maintain a parallel IP/TDM infrastructure that adds cost and prevents them from taking full advantage of IP telephony. Phase 3: VoIP Transit Using The introduction of Trunks addresses many of the remaining network cost and flexibility issues. As depicted in Figure 5, Trunks allow the enterprise to take advantage of termination and origination services that effectively transition connectivity for long-distance and local access calls to the Service Provider. The enterprise now only needs a single IP pipe to the cloud. Circuit-switched hand-off still occurs for communications between enterprises, but it is now handled through the Service Provider network at a lower cost. Off-net calls to numbers are carried on the Service Provider s IP backbone to the closest gateway, where the call is converted to TDM for the last mile. Per-minute toll charges on these calls

10 8 are typically greatly reduced, since lower local rates are applied and fewer intermediary carriers are involved in handling the call. In addition to reduced toll charges, enterprises also directly benefit with hard dollar savings through the elimination of monthly recurring costs associated with multiple circuits and the capital/operating costs of dedicated interface hardware. These hard dollar savings are even greater for enterprises with large numbers of branch sites, as each of these sites can now operate with fewer LEC or CLEC trunks. With the advent of local number portability, most calls destined for the branch can be routed via from the Service Provider into the enterprise data center. These calls can then be delivered to the branch using the enterprise s private WAN or MPLS network, reducing the number of traditional local trunks needed in the branches to just the number required for survivability or emergency services (911). Server Benefits of Trunks Single IP link for voice/data Converged Infrastructure cost savings VoIP transit reduces toll charges Open softwarebased architecture One protocol () for all communications Inter-Enterprise Voice via Phones Phones LAN Telephony Feature Server Telephony Feature Server LAN Router Long Distance Server Data/ VoIP Router Data/ VoIP Gateway Gateway SP SP Data/ VoIP Gateway Gateway Data/ VoIP Partner Supplier Sites Local Branch Sites Intra-Enterprise Voice via Figure 5: Trunking A recent survey of a few Service Providers offering these types of Trunking services revealed the following rates: Service Provider 1 Service Provider 2 Termination On-Net $0.005/minute $ $0.0072/minute Termination Off-Net $0.029/minute $ /minute As figure 5 shows, these savings can be extended even further by also deploying telephony within the enterprise. By unifying on, the need for dedicated hardware devices is reduced, enabling an open, software-based communications infrastructure in which telephony and other communication services become modular applications. The result is simplified, open, and flexible enterprise communications.

11 9 Phase 4: Future Path Incorporating Universal Directory Services The second contributor to the islands of VoIP connectivity problem has been the lack of a universal directory service like ENUM (Electronic Number Mapping), which provides a method for Service Providers to encode telephone numbers (formally known as E.164 numbers) into the Domain Name System (DNS). ENUM is a scalable, centralized directory that translates E.164 telephony numbers into IP addresses (or their equivalent, such as resolvable host names). This directory system is based on the Internet s DNS, which is a highly scalable, hierarchical, directory service for translating domain names into IP addresses. ENUM was designed as a database that a VoIP Service Provider could consult in order to determine the IP address of an E.164 telephony number. With a common directory source such as ENUM in place, highly efficient peering interconnections between communities of enterprises become a reality. IP-based voice networks finally take on the best characteristics of the IP internet; ubiquitous coverage and easy network inter-connectivity over IP for all communications, as illustrated in Figure 6. With a common directory source such as ENUM in place for use within a service provider network, highly efficient peering interconnections between communities of enterprises become a reality. For enterprises, the use of this capability can be transparent; inter-enterprise calls are handed off to the Service Provider, who then uses ENUM to resolve the E.164 digits to an IP address for routing the call (Figure 6). Benefits of the all IP network Eliminates circuitswitched hand-offs Phones LAN Telephony Feature Server Router Server Partner Supplier Sites Single IP link for voice/data Converged infrastructure cost savings VoIP interconnections between Enterprises Open softwarebased architecture Unification of all real-time communications over Inter-Enterprise Voice via Phones Telephony Feature Server LAN Server Data/ VoIP Data/ VoIP Router SP SP ENUM Data/ VoIP Data/ VoIP Intra-Enterprise Voice via Branch Sites Figure 6: Peering with ENUM Deployment Call Center case study Another example, this one of a retail enterprise with a large number of store locations, will illustrate how trunking can also provide extensive benefits in a call center environment. In this example, there is no direct connectivity between the stores and the company s central call center. The existing retail environment has multiple lines and employees to handle sporadic incoming call traffic. In addition the store employees

12 10 generate millions of 800 minutes per month calling into the call center for sales assistance. The company has no budget to upgrade the retail store phone systems. The current network topology results in several problems. In addition to the high cost of the 800 traffic, the limited lines available in each store result in inconsistent customer service because of intermittent Busy signals at the stores. In-store customer service also suffers when employees spend too much time handling local calls. Contact Center Example of Benefits No expensive upgrade required for existing store phone systems Store employees freed up to better service in-store customers Improved call center improves customer service by eliminating busy signals at stores Reduction in store call traffic reduces the number of lines needed at each store allows the elimination of extra phone lines Reduction in tollfree 800 number charges Networking enables a reconfiguration of communications to address the problem. By implementing -based 800 number and Local Number Portability for DIDs, 800 number and local DID number calls are converted by the Service Provider to and transported directly to the call center over IP. This allows the call center to handle the majority of calls, but still perform a call transfer to the local store (possibly over the private WAN) if localized help is needed. The end result is a reduction in local services, lower 800 number charges, fewer number of local trunks at the retail stores, the potential for reduced employee head count at the retail stores, and improved customer service. Call Center 3 Call center handles majority of calls. Agents transfer the call back to store if needed 2 4 SP takes back active call and re-routes over gateway to local SP 1 Gateway Local DID SP terminates call locally, transports to call center over Customer dials number for local store Figure 7: Networking for the Call Center 5 Stores Local Customer receives one call service, including local store support Local Local Store Customers Outbound local and long distance services can achieve similar savings levels for enterprises with extensive outbound calling operations. Outbound calls are transported over the Service Provider s network and terminated to the at the last mile, reducing the impact of toll charges. TDM Call center eliminates dozens of T-1, replacing them with a single IP link

13 11 A recent survey of a few Service Providers offering these types of Trunking services for call centers revealed the following rates: Service Provider 1 Service Provider 2 Inbound DID $0.029/minute $0.005-$0.02/minute depending on pre-payment Toll Free Inbound $0.039/minute Termination On-Net $0.005/minute $ $0.0072/minute Termination Off-Net $0.029/minute $ /minute Avaya: Building the -Connectivity Ecosystem For Avaya, is a catalyst for the evolution of enterprise communications as an embedded multi-modal communication core service that can be integrated with other business applications. Avaya is committed to helping its Enterprise customers fully exploit the advantages of Networking. Its commitment is reflected both in the extensive portfolio of products and applications and its programs designed to foster interoperability within the ecosystem. Avaya is building an ecosystem requiring the integration and collaboration of information and processes from thousands of Developers, Service Providers, System Integrators, Customers, and BusinessPartners. Avaya has interoperability testing and certification programs for both enterprise and service provider equipment/application vendors. An online testing facility is also available through the DeveloperConnection (DevConnect) program, enabling companies to remotely test and verify basic interoperability. Avaya trunking conforms to applicable standards. Avaya is also participating in connect, an industry initiative to define a standards-based approach to direct IP peering between -enabled IP PBXs and VoIP Service Provider networks. Avaya is strengthening its commitment to an open call model through the combination of Avaya Communication Manager and the Converged Communications Server. This will simplify the programming interface for Avaya Communication Manager and enable developers to create web services-based applications enabled by Avaya communications capabilities that combine the power of Avaya Communication Manager s feature functionality with the broad and open reach of.

This layer unifies all enterprise real-time communications over an open -based infrastructure, and provides the glue that binds with Avaya MultiVantage Communications Applications, exposing them as Web service components that can be easily invoked through standards-based clients or business applications, or as open APIs that provide a secure, reliable and highly scalable application development platform for access to Avaya Communication Manager services. The Converged Communications Server is a family of related product offerings that currently consists of two primary components: Enablement Services: Avaya Enablement Services combine the standard functions of a proxy/ registrar server with trunking support and duplicated server features to create a highly scalable, highly reliable communications network supporting telephony, instant messaging, conferencing, and collaboration solutions. These services are modular software components that run over Linux on a dedicated industry-standard server platform, and are designed to operate in a networked hierarchical topology for scalability. Application Enablement Services: Avaya Application Enablement Services consolidate the Avaya existing application enablement assets such as Avaya Communication Manager Application Programming Interface (CMAPI) and Avaya CT into a single, Linux-based platform. This enables enterprises to leverage the tremendous variety of computer-telephony integration and interactive response applications developed for these interfaces. Application Enablement Services allow for powerful new applications to be written and deployed that fully leverage Communication Manager via standards-based APIs and Web service components. Enablement Services and Application Enablement Services are modular offerings that are ordered independently and implemented as needed by the enterprise on separate, dedicated industry-standard servers. In combination, the new services of the Converged Communications Server create an application environment that combine the loosely coupled multi-modal services and presence capabilities available via a -

15 13 based architecture with the open APIs that expose the full breadth of features and functionalities of Avaya Communication Manager. Trunking In many cases, enterprises with Avaya Communication Manager solutions can start to take advantage of by adding Converged Communications Server ( Enablement Services) to establish a standard compliant (IETF RFC 3261) network. In this configuration, Communication Manager supports for internal telephony communications and trunk connections to the Service Provider. Instant Messaging (IM)/Presence Once Enablement Services are in place, a gradual step-by-step migration path allows the enterprise to maximize the benefits of while fully preserving compatibility and investment protection with existing H.323, digital and analog endpoints and infrastructure. For example, Enablement Services can be leveraged to introduce secure Enterprise Instant Messaging (IM) and user presence integrated with telephony through the Avaya IP SoftPhone and IP Agent client applications. Avaya IP SoftPhone and IP Agent combine H.323 telephony support with a -based IM client and a presence-enabled contact directory that supports both voice and IM communications. This allows enterprises to extend the benefits of user presence and IM to all users without the need to make extensive changes to their existing voice infrastructure. Telephony supports both numerical (telephony) and alphanumeric addressing, providing a critical bridge for communications between and Internet networks. This allows users on either network to reach any other user without giving up existing devices or the advantages of each. When enterprises are ready to make the transition to Telephony, Avaya Enablement Services will allow them fully leverage the benefits of while supporting full compatibility and use of their existing infrastructure and endpoints. For enterprises that have already deployed H.323 IP Telephony, the migration process can be initiated immediately and transitioned at whatever pace is desired. Once registered and licensed on Enablement Services, existing Avaya 4602SW/4610SW/4620SW/4621SW IP phones can convert their operation from H.323 to through a simple firmware upgrade. Avaya IP SoftPhone users have a similar migration path to telephony through the Avaya SoftPhone, which supports signaling for both IM and telephony communications. User Mobility is well-suited for mobility requirements. When a user logs onto a device, it registers the user and sends the URI of the device to the registrar service, which is used to route calls to/from the user. Avaya Personal Profile Manager, a user mobility application within Enablement Services, leverages this capability to create a custom work environment that follows the user. Personal Profile Manager is centralized service that resides in each Home Proxy Server and communicates with its assigned endpoints to receive, store, and distribute user profile information. Applications Through Enablement Services, a number of Avaya MultiVantage Business Communications Applications, including Communication Manager telephony and Meeting Exchange web/audio conferencing, become available to a wide range of standards-based user agents, web-based applications, and communication devices to create a new paradigm of Converged Communications that will lead to increased flexibility and cost efficiency.

16 14 Avaya Communication Manager is the next generation of Avaya call processing software. Designed as an open, scalable, and highly reliable telephony solution, it effectively scales from under 100 users to as many as 36,000 on a single system and to more than one million users on a single network. Designed to run on a variety of Media Servers, Avaya Communication Manager provides centralized call control for a resilient, distributed network of media gateways and a wide range of analog, digital, and IP-based communication devices. Avaya Communication Manager integrates with the Avaya Converged Communications Server ( Enablement Services) to become a telephony feature server that supports seamless communications between existing analog, digital, and IP phones and -based endpoints. With Avaya Communication Manager Extended Access, standard phones can even gain access to advanced telephony features. Avaya Meeting Exchange is an audio and web conferencing solution that is supported by the Avaya S6200 server. The standards-based S6200 scales from 24 to 240 IP ports. It uses as the signaling protocol for conferencing participants, and as a communication protocol that allows the conferencing application to run on standard third party media servers. is also leveraged for redundancy redirecting calls to a back up system if necessary. The S6200 s standards-based architecture allows enterprises to leverage existing infrastructure investments, smoothing the migration from TDM to IP and delivering ample cost and efficiency benefits. For larger-scale deployments the S6200 can be deployed with an S6800 media server to support up to 10,000 ports.
