1 Brochure More information from North American VoIP Access and SIP Trunking Services Market Description: The VoIP access and SIP trunking market is entering into a growth stage and is moving closer to becoming the de-facto communications link from business customers' premises to service providers' networks. Vendors, service providers, and channel partners can use this analysis to identify growth opportunities and develop sustainable business strategies. The study discusses market drivers, restraints, and trends. It also provides market share analysis and competitor assessment. Finally, the study provides a market forecast in terms of users and revenue. This analysis covers the North American market for the period 2012 to SCOPE Geographic Coverage: North America Study Period: Base Year: 2012 Forecast Period: Monetary Unit: US Dollars MARKET DEFINITIONS This study focuses on next-generation access services including: - VoIP trunking (converged access lines connecting with time division multiplexing (TDM) enterprise telephony platforms). - Session Initiation Protocol (SIP) trunking (converged access lines connecting with IP telephony platforms). - Basic VoIP access services (converged access lines connecting with low-end key systems or directly with telephony endpoints). VoIP access and VoIP/SIP trunking services involve the provision of integrated circuits using VoIP or SIP technologies t- businesses that have implemented premises-based business telephony solutions (private branch exchanges (PBXs)/IP PBXs or key systems) or, sometimes, t- businesses that have n- call-control platforms on the premises. These services enable companies with some enterprise telephony customer premises equipment (CPE) t- converge their voice, video, and data access networks. VoIP access or SIP trunking service bundles typically include local dial tone, long-distance calling, and a limited set of call-management and control features such as extension dialing among intra- and inter-office locations. VoIP Access and VoIP/SIP Trunking Services VoIP access and SIP trunking services essentially direct enterprise customers toward a path of gradual transition t- fully converged, IP-based networks. They allow businesses to enjoy the benefits of IP telephony while eliminating the need t- forklift-upgrade their networks. Line-side or trunk-side VoIP access services interfacing with a legacy TDM system or endpoints typically require the deployment of a media gateway or an integrated access device (IAD) at the customer's premises, while SIP trunking services are typically deployed as T1 PRI replacement when connecting t- SIP-enabled enterprise telephony platforms. Even in native SIP environments, enterprise session border controllers (E-SBCs) may be needed for protocol normalization, session management, and security purposes. Many service providers are bundling VoIP access and SIP trunking services with various network based communications applications and capabilities, such as hosted auto attendant, voic , unified messaging (UM), and mobility/fixed-mobile convergence (FMC) or some data services including Web hosting, Web e- mail, managed security, and so on.

2 For many of these service providers, a VoIP access or trunking service is perceived as a migration path to a fully outsourced hosted IP telephony solution. Session Initiation Protocol (SIP) SIP is a media signaling protocol that facilitates set-up, control, and tear-down of IP-based voice, video, and data communications sessions. SIP is designed as an application-layer protocol that is independent of the transport layer, enabling it to operate in Transmission Control Protocol (TCP), User Datagram Protocol (UDP), or Stream Control Transmission Protocol (SCTP) environments. SIP is a distributed peer-to-peer protocol, with which intelligence and features are embedded in endpoints (e.g., servers, phones, gateways, and appliances) rather than at the network core. Centralized or Distributed SIP Trunking - A common approach to deploying SIP trunking services to enterprises has been a centralized model, based on deploying all of an enterprise's trunks at headquarters or a data center location and routing voice traffic for remote locations across the enterprise's wide area network (WAN). - This approach is very cost-effective in pooling telephony resources, but requires branch survivability contingencies, including analog or alternative local dial tone. - Increasingly, service providers are offering distributed SIP trunking options to enterprise customers. Under the distributed model, an enterprise's SIP trunks are treated as a shared resource, but deployed throughout the enterprise locations. - Enterprise administrators can reallocate SIP trunks among the various locations on demand, while dealing with a single vendor for billing and support.
