13 Overview Lync Online Dedicated Enterprise Voice enhances the Microsoft Lync 2013 client experience with PCbased public switched telephone network (PSTN) voice services, allowing users to place and receive telephone calls using the Lync client as a soft phone. With the Enterprise Voice (EV) add-on feature, you can now expand your capabilities beyond Instant Messaging (IM) and Presence. EV is optimized for highly mobile PC-centric users. EV reduces the costs associated with maintenance and repair of on-site voice equipment including fees associated with private branch exchange (PBX) moves and add or change activities. With EV, you can now reduce the financial burden of maintaining a legacy telecommunications environment while providing PSTN voice services for users from virtually any broadband connection. Lync Online Dedicated recently introduced PSTN dial-in conferencing as part of the EV service offering. A second method of PSTN connectivity, known as an on premise Session Border Controller (SBC), was also introduced. This allows you to connect to both the PSTN and a legacy private voice network. Lync Online audio conferencing enables users to join a Lync audio conference via a PSTN phone. This means both users within and persons outside your organization can join audio conferences from a PSTN phone (for example a home or mobile phone). The PSTN Dial-in Conferencing feature is only available in select countries and each audio conference meeting organizer must have the Dial-in Conferencing feature enabled. The Lync Online Dedicated EV service offering requires deployment of one of two PSTN connectivity options: 13

14 Session initiation protocol a (SIP) trunking using a qualified Lync Online Dedicated provider. SIP trunking provides PSTN connectivity once you obtain service from a qualified SIP trunking provider 1. Microsoft does not sell SIP trunking services to customers directly. You are responsible for ordering the SIP trunking service from a qualified Lync Online Dedicated SIP trunking service provider. Enterprise Voice with on-premise Session Border Controllers (SBCs). EV with qualified on-premise SBCs 2 provides you with the option to connect a customermanaged private voice network to the Lync Online Dedicated Service for inbound and outbound PSTN services as well as your private voice network. The SBC provides the demarcation and interface point between the Lync Online Dedicated Service and your managed voice network. Depending on the capabilities of the SBC, you can integrate existing voice network components, like standard SIP PSTN gateways or IP-PBXs. Lync Online Dedicated Enterprise Voice features EV has an array of features including: 1. Placing and receiving calls to and from the PSTN and/or legacy PBX via PSTN. EV users can use Lync Online with an approved audio device to call any PSTN number. 2. EV transforms a PC into a unified communications end point by integrating PSTN phone calling with , IM, and Microsoft Office applications from almost any broadband connection without the need for virtual private network (VPN) or corporate network connections. 1 Microsoft Unified Communications Open Interoperability Program (UCOIP) certification (SIP trunking services) 2 Microsoft Unified Communications Open Interoperability Program (UCOIP) certification (Session Border Controller) 14

15 3. PSTN dial-in conferencing allows EV enables users to organize a Lync audio conference that PSTN users can join. 4. Use of one corporate phone to ring multiple numbers using the Simultaneous Ring feature. Users can set calls for a corporate number to ring at additional numbers like a home or mobile phone so that the user can receive calls from virtually anywhere. 5. Voic is accessible from any Microsoft Outlook capable device, PSTN phone, or directly from the Lync client. Exchange Online Unified Messaging delivers voic s to a user s inbox. Note: Deployment of Exchange Online Dedicated is required for EV customers that desire Exchange Unified Messaging (EUM) for voic . 6. The Click-to-Call feature can be used from within Microsoft Office applications (like Outlook and SharePoint) to collaborate with peers quickly and efficiently. 7. The Transfer Calls feature enables users to transfer calls to another user or PSTN phone number. 8. The Call Park feature enables you to dispatch active conversations to a call parking lot. These calls can be retrieved from different locations or by other parties. 9. Placing calls between EV users utilizes peer-to-peer Voice over Internet Protocol (VoIP), reducing PSTN-based call routing costs. 10. EV provides even greater reliability for PSTN voice services in the event of a single data center failure or impairment. It employs a robust service continuity design for PSTN voice services that are enabled at redundant data centers. 11. The Scheduled Meeting Delegation feature enables an EV user to schedule meetings and manage calls on behalf of a user, also known as boss/admin scenario. 12. The Dial-in PSTN Audio Conferencing feature allows Lync meetings enabled for dial-in access to allow users to join a Lync audio conference via PSTN. For example, users can also dial into meetings using a home or mobile phone without the need for a third-party conferencing provider. 15

Customer network locations Carrier SIP trunking provider items and pricing considerations The SIP trunking provider maintains an independent billing and contractual relationship with you. You are responsible for any charges pertaining to the SIP trunking service, like monthly recurring charges for bandwidth and data network port fees. Once you select a SIP trunking provider, Microsoft works with you and the SIP trunking provider to enable services. The costs for SIP trunking vary widely by carrier. Be sure to examine each carrier s SIP trunking and data circuit pricing models thoroughly before making a selection. The following list of provider items and pricing considerations are intended as a guideline for customers to determine which service provider best meets their SIP trunking PSTN service needs. Provider item Service availability. Considerations Where does the service provider have local direct inbound dialing (DID)/direct dial-in (DDI) lines available (cities and countries)? Note: Microsoft recommends you be aware of the Lync Online data center locations prior to having a discussion with the service provider. Inbound per-minute metering. Are inbound calls metered, charged per minute, or unlimited as part of a monthly recurring fee? Outbound per-minute metering. Are outbound calls metered, charged per minute, or unlimited as part of a monthly recurring fee? Outbound calls within local DDI/DID rate center. Are outbound calls within the local DDI/DID rate center metered, charged per minute, or unlimited as part of a monthly recurring fee? Domestic inbound toll-free service. Is the service provider able to provide domestic inbound toll-free numbers and terminate those toll-free numbers via their SIP trunking service? 23

24 Provider item Domestic inbound toll-free service metering. Considerations Are domestic inbound toll-free service calls metered as part of any monthly inbound minutes of use surcharge, in addition to a toll rate? International inbound toll-free service. Is the service provider able to provide international inbound toll-free numbers and terminate those toll-free numbers via their SIP trunking service? Note: We recommend that you ask the service provider about the ability to port numbers from an international carrier. International inbound toll-free service metering. Are domestic inbound toll-free service calls metered as part of the any monthly inbound minutes of use surcharge, in addition to a toll rate? Domestic outbound toll-free service. Is the service provider able to provide termination to domestic outbound toll-free numbers? Domestic outbound toll-free service metering. Are domestic outbound toll-free service calls metered as part of any monthly outbound minutes of use surcharge, in addition to a toll rate? Outbound toll call metering. Are outbound toll calls metered as part of any monthly outbound minutes of use surcharge, in addition to a toll rate? Outbound N11 call metering. Are outbound calls to N11 metered as part of any monthly outbound minutes of use surcharge, in addition to a toll rate (for those N11 services that are charged a premium)? Inbound calling party name display. Is inbound calling party name display supported? Is there an additional charge for enabling this feature? Service provider customer on-net toll-free calling. Are all calls to and from carrier network terminations and originations toll-free for intracustomer terminations where DID s, origination and termination (which are VoIP), remain on the carrier s network? Service provider customer on-net toll-free calling with time division multiplexing (TDM). Are all calls to and from the carrier network terminations and originations toll-free for intra-customer terminations where DID s, origination and termination (including a mixture of VoIP and/or TDM), remain on the carrier s network? 24

25 Provider item Service provider management web portal. Considerations Does the service provider provide a web portal which enables the following reports? Online network management Online network performance reports Online usage reports: Call volume Usage detail Per-call billing Monthly usage detail Table 2 - Carrier SIP trunking provider items and considerations 25

26 Carrier pricing elements The following table lists the typical pricing elements for SIP trunking services. Item Setup Monthly Recurring Physical network connectivity for the wide area network (WAN) to the Microsoft Online data centers. Varies by carrier, circuit type and circuit size. Yes Metered Items Based on Usage Varies - Burst traffic may have usage rates. Concurrent SIP talk paths. Additional features: Varies by carrier. Yes. Rates often mimic mobile phone rate plans, bundling minutes-permonth and/or discounted toll rates for paying more per talk path to increase aggregate allowances of minutes and discounted per-minute toll rates. Yes Varies by: Varies by carrier. Varies by carrier. Varies by carrier. Carrier. Per minute inbound. Per minute outbound. Per minute toll calls. Per minute local area toll. Voice Burst (adding concurrent talk paths during peak times). On-net toll free calling between legacy PBX and Lync Online users. Behavior when exceeding the voice committed bandwidth. Varies by carrier. Varies by carrier. Varies by carrier. Table 3 - Carrier pricing elements SIP trunking circuit To provide PSTN SIP trunking services for Lync Online Dedicated EV, the SIP trunking service provider must enable dedicated multiprotocol label switching (MPLS) circuits into the Lync Online Dedicated data centers. Each Lync Online Dedicated customer is deployed in at least two data centers and connectivity to the service provider s SIP trunking network is required for each of the Lync Online data centers enabled for voice. 26

27 The Lync Online Dedicated EV Service is engineered to be highly available. A secondary regional data center and alternate SIP trunking paths are used in the event of a data center failure. The Lync Online Deployment team works with the service provider to determine the location for SIP trunking demarcation. The standard configuration for PSTN SIP trunking service providers requires redundant links to be deployed in each Lync Online data center (see Figure 2). The circuits terminate into an Access Edge managed by Microsoft. If a service provider requires on-premise equipment to be deployed (like a router), rack space is coordinated by the Lync Online Deployment Team (see Figure 3). The service provider is required to provide Out-of-Band (OOB) management using a plain old telephone service (POTS)/analog line to any devices in the Lync Online data center. SIP trunking partner connectivity options Figure 2 Redundant MPLS links 27

28 Figure 3 Single MPLS link with on-premise router 28

29 EV with on-premise SBCs Using qualified SBCs gives you the option to connect a voice network you manage to the Lync Online Dedicated Service for inbound and outbound PSTN services. The SBC provides the demarcation and interface point between the Lync Online Dedicated Service and the voice network. Depending on the capabilities of the SBC, you can integrate existing voice network components, like a standard SIP PSTN gateway, IP-PBXs, and devices that don t natively support the required configuration for Lync 2013 Server, like SIP over transmission control protocol (TCP). The Lync Online Dedicated Team will produce SBC configuration guides for your supported devices that provide guidance on how to configure the External Edge of the SBC, which communicates with the Lync Online Servers. The Internal Edge of the SBC, which communicates with your internal voice network, configuration varies based on your environment. Any SBC partner documentation should also be used as guidance. Limits EV with on-premise SBC is used for voice calls. It doesn t allow for: Third-party Presence integration. GetPresence. SetPresence. Video integration. 29

30 Figure 4 On-premise SBC Capacity EV with on-premise SBC service utilizes SBCs as the interface for your voice network. The SBCs need to be sized accordingly to support the anticipated voice traffic for inbound and outbound PSTN services. Each SBC has a maximum number of concurrent talk paths (voice calls) that can be supported per device. As part of the EV with on-premise SBC service discovery process, the Lync Online Deployment team will work with you to determine the number of talk paths required for each deployment. SBC manufacturer guidance as well as the Enterprise Voice bandwidth calculator can be used to estimate the number of concurrent talk paths required based on the number of EV enabled users. As a design input, each Lync 2013 Mediation Server can support 800 concurrent voice calls and is deployed in an N+1 configuration in the Primary EV data center and an N configuration in the Secondary EV data center to match required capacity. 30

31 The following capacity examples should be used as guidelines only. You should work with a Microsoft Premier Deployment resource to calculate actual values. Lync 2013 Mediation Server supports up to 800 concurrent talk paths. Customer SBC ACME Packet supports up to 20,000 concurrent talk paths. Deployment size Number of talk paths required Mediation Servers in primary voice data center Mediation Servers in secondary voice data center Number of SBCs in customer network Small Large X-Large Security To ensure compliance with existing encryption security controls within the Office 365 Dedicated/ ITAR environment, the customer-supplied SBC must be configured to encrypt both SIP signaling and media traffic. Lync 2013 Server uses Transport Layer Security (TLS) to encrypt SIP signaling and uses Secure Real-time Transport Protocol (SRTP) to encrypt the media (audio packets). For more information, see: TLS and MTLS for Lync Server 2010 [MS-SRTP]: Secure Real-time Transport Protocol (SRTP) Extensions Customer SBC support You are responsible for both configuration and support of the SBC required for EV and PSTN dial-in conferencing. In the event of an operations incident or outage, the Lync Online Service Operations works with you to determine the nature of the problem for inbound and outbound PSTN and PBX services. If the issue is attributed to the SBC or your voice network, the Lync Online Service Operations opens a tracking ticket to monitor the resolution. Network The External Edge of your SBCs must be on a network that is routable to and from the Lync Online Dedicated Server Network (MGS). You can choose to implement network access control lists (ACLs) as needed. The network ports used for SIP signaling TCP 5067 must be enabled as well as the Lync 2013 Server Audio Ports UDP/TCP and The Lync 2010 and 2013 Mediation Servers in the Lync Online data centers are only configured with a single network interface card (NIC); no separate voice virtual local area network (VLAN) is required for 31

32 this integration. The Lync 2013 and PSTN listening IP addresses are the same and must be able to access the External Edge of the customer-managed SBC. Network Quality of Service Network Quality of Service (QoS) is a required configuration. Lync Online Dedicated Servers are configured by default to mark the Differentiated Services Code Point (DSCP) to EF/46 for all audio streams. You can configure most SBCs to also support audio packets marking. In that case, EF/46 should be used. You can further customize this code point by re-marking packets as in or out at the network demarcation point to convert EF/46 to any other desired code point. Dial plan A dial plan is a grouping of telephone numbers that make up a site within a customer deployment. Each site can have a unique dial plan that is configured in both Lync 2010 and 2013 Server, offering the best possible user experience when placing outbound phone calls. EV can be configured to support most typical enterprise customer configurations. A dial plan is created in the Lync 2013 Server, using a Location Profile with a specific set of normalization rules created when an enterprise customer is enabled for EV. If PSTN dial-in conferencing is planned for your deployment, a dial in conferencing region for each dial plan needs to be specified. This information is used when users create scheduled conferences, populating the appropriate dial-in access number associated with each user s assigned dial plan. 32

33 Figure 5 Dial plans SBC dial plan Lync Online Dedicated requires E.164 routing for all configurations. All calls leaving the Lync Online Dedicated Service have the telephone number formatted as an E.164 format. You must configure inbound calls to Lync via the SBCs also using E.164 formatted numbers. No short-dial or non-e.164 formatted numbers are accepted. If you want to deploy short-dial or non.e.164 formatted numbers, you can manipulate the telephone number once it has entered you voice network from Lync. Supported SBCs SBCs provide a secure gateway capability between your data center and the Microsoft Online Dedicated environment. All SBCs that qualified for Lync Server 2013 are supported in Lync Online Dedicated. For details, please visit the Session Border Controller section of the Infrastructure qualified for Microsoft Lync page. 33

34 Mixed connectivity options Lync Online Dedicated can support the SBC and SIP trunk connection types if they are deployed for a single customer with some specific configurations and guidelines. Lync Online only supports routing outbound calls to either EV with on-premise SBC or a SIP trunking service provider, but not both for the same site (location profile). Inbound PSTN calls You can receive PSTN inbound calls using EV with your on-premise SBC in addition to a SIP trunking service provider. As some SIP trunking providers may not be able to provide PSTN telephone number service in all countries where you have users, a combination of deploying SIP trunking as well as SBCs may be required if you want voice enablement of users in countries without SIP trunking availability. Outbound PSTN calls You can also enable PSTN outbound calls using both EV with on-premise SBC and a SIP trunking service provider by segmenting users with unique blocks of DID/DDI numbers typically provisioned at different EV Sites. The user s voice policy controls which trunks are used for outbound calling. If you want least cost routing within your private voice network, choose the EV with on-premise SBC connection type. 34

35 Customer prerequisites The hardware and software requirements for Enterprise voice users are identical to those for Lync Online users, as specified in the Lync Online service description for Office 365 Dedicated Plans. Enterprise telephone numbers listed in your Active Directory (AD). All user and contact objects must be in E.164 format in your AD. (For example, or ) This includes work, home, and mobile telephone numbers published in your AD. Note: Be mindful of personnel and other business systems that feed into your AD. All user and contact objects must have a telephone number set in the multi-valued Extension Number Attribute using for provisioning following the Request for Comments (RFC) 3966 format with an extension number assigned. See the Formatting Enterprise Voice telephone numbers section for more information. The most current version of the Microsoft Managed Services Service Provisioning Provider (MMSSPP) is recommended when using EV. Refer to the MMSSPP Customer Deployment Guide and Provisioning Interfaces Handbook for more details. Split-tunnel virtual private network (VPN) systems must be enabled to provide deterministic VoIP performance for remote VPN users. Multiprotocol label switching (MPLS) connections are required for all Microsoft Online data centers. Network assessment to confirm your network is suitable to deploy EV. 35

36 Deployment requirements The following list includes the high-level deployment activities required to successfully deploy EV in your environment. Note: It is presumed you are informed of the regional data center requirements to provide voice services. This may also include communication with the Microsoft account team responsible for service expansion. Customer deliverables Select public switched telephone network (PSTN) connectivity method(s): o o Select a SIP trunking carrier partner from the Microsoft Unified Communications Open Interoperability Program (UCOIP) certification page ( SIP trunking section) qualified to work with EV. Select a qualified SBC partner from the UCOIP certification page ( Session border controllers section). Provision EV users via Active Directory (AD). Enabled users are synced with the Microsoft Online Services Identity and Provisioning Service. Acquire and plan distribution timing of Enterprise Voice UC Optimized USB headsets and devices. Select users within locations to enable PSTN voice services. Select and deploy the Lync Online Dedicated and Exchange Online Dedicated service offerings. EV is deployed after the initial service-ready date for Lync Online. Determine the implementation methodology of the Quality of Service (QoS) for deterministic VoIP performance within your corporate network. Note: This is optional, but strongly recommended for the best voice quality performance. If using on-premise SBC, you are responsible for: o o Purchase and deployment of SBC pairs, one pair per region where EV is deployed. For example, a SBC pair for North America and a pair for Europe. Configuration of SBC per Lync Online Dedicated/manufacture guidance, including: Certificates for TLS and SRTP. Dial plan configuration. Connectivity to the private voice network/pstn. 36

37 o Testing with the Lync Online Deployment Team. Submit dial plan details via the Customer Request Analysis System (CRAS) template (6176-LYNC- Add or Remove Voice Site). Submit telephone numbers reserved for synthetic transactions. Microsoft adds them to the Lync topology and configures them to proactively monitor the availability of the PSTN route. Successfully execute the EV Test Plan. Train IT Helpdesk and end users. See Lync On-Demand Training for more details. Carrier partner deliverables (if using a PSTN SIP provider) Provision circuits to Microsoft Online data centers. Provide a data transport network layer (typically MPLS) where SIP trunking services reside for PSTN connectivity. Provision a dial plan in the SIP trunk cloud. Be in compliance with any required telecommunication regulations. Microsoft deliverables Install and configure additional Lync servers as required for EV in Microsoft Online data centers. Once the dial plan has been submitted by the customer via the CRAS process, Microsoft provisions the dial plan within the Lync Online servers. Configure Exchange Online Unified Messaging servers. Shared deliverables Note: These activities will be executed per Data Center region as defined in the contract, which may depend on the completion of required service expansion projects. Carrier partner with customer: Determine a service methodology for emergency calls. Contract with selected carrier: For toll, usage, and monthly recurring voice and data fees using a direct contractual relationship between the customer and the SIP trunk carrier. Note: Microsoft does not provide PSTN SIP trunking services to customers, nor does it facilitate, govern, or determine billing, financial, or other contracts between the customer and the SIP trunk carrier. Customer with carrier and Microsoft consultation: Order concurrent voice SIP trunking talk paths to Microsoft Online data centers from the carrier partner. 37

38 Microsoft with customer: o o o o o o Specify the user provisioning and the customer dial plan integration requirements. Review and analyze the existing customer voice and data environment. Gather environmental and customer requirements. Complete EV Detailed Data Exchange (DDE) with Microsoft Online Deployment Services Group (DSG) to determine which locations will be enabled with PSTN voice services. Perform Service Validation ahead of Service Acceptance. Work together to troubleshoot any open items before declaring Service Ready. Country availability matrix The list of countries that have been approved for EV and PSTN dial-in conferencing are located on the Enterprise Voice International Availability page. Final determination of suitability for deployment must be decided by conducting a network assessment to determine if the connectivity between your location and the Microsoft data center is of sufficient quality to support EV and PSTN dial-in conferencing. Note: Countries are evaluated against 4 criteria: 1. Does the country have VoIP regulatory restrictions? 2. If there are no regulatory restrictions, are there sanctions prohibiting the offer of VoIP services? 3. What is the distance from the data center? 4. What are the network and telecommunications infrastructure in the local region? Customer responsibilities: Perform and complete a network assessment. This is used to evaluate locations identified as VoIP capable regions and point to point latency measurement performed in order to reconcile the predicted VoIP capabilities and latency against actual values. Important: No guarantees (either implied or in writing) are asserted by the results provided by the latency estimate calculations provided in this document. Share and discuss findings of the network assessment. Share and discuss findings of the point-to-point latency measurement findings. Microsoft responsibilities: Provide customer server Domain Name System (DNS) values or the equivalent to be used for point-to-point latency measurements for existing customers. Provide information required to the team performing the pre-implementation network assessment to be used to determine the feasibility of feature deployment. 38

39 Note: The service is provisioned only for users in countries where Microsoft explicitly offers EV. User location (UL) is determined by a user s office address, as listed in your AD. 39

40 Customer data network elements Lync Online Dedicated is a hosted service, based upon Microsoft Lync 2013 Server. It provides a flexible, scalable and highly available communications solution to end users. Delivered from the global network of Microsoft data centers, Lync Online service relies on the same network architecture and components used for Microsoft Exchange Online Dedicated and other Microsoft Online dedicated services. The service is configured using an Active/Active data center topology, where each of two geographically separate sites hosts approximately half of a customer's total user population. Each site has the capacity to host 100% of the users. The Active/Active topology enables each site to fail over to the other in service, pushing all of the user population over to one site, while maintaining service continuity and enabling disaster recovery scenarios. EV is currently configured in an Active/Passive topology to optimize the voice experience by having the PSTN egress in the same Active data center with the EV enabled users. The EV services will failover to the Secondary data center when a standby SIP PSTN trunk group is configured. In the on-premise SBC PSTN connectivity model, EV services will failover to the Secondary Lync Online data center using the customer supplied pair of SBCs. Dedicated private-line or multiprotocol label switching (MPLS) network connections are required between the customer network and all regional Microsoft data centers. These connections must be appropriately designed, so that either can support 100% of the Lync Online traffic at all times. Bandwidth for other Online Dedicated services, like Exchange Online and SharePoint Online, should also be considered. Note: Microsoft Online does not support Quick Start/On-Net VPN for any Active data centers. For more information, refer to the Microsoft Office 365 Service Descriptions and Service Level Agreements found at the Microsoft Download Center. Enterprise Voice traffic thresholds Several factors contribute to a network s ability to carry quality voice. The International Telecommunication Union (ITU) specifies that from the time speech is uttered, it should reach the ear of the listener within 150 milliseconds (ms) for an optimal experience (one-way delay). At 250ms, the 40

41 delay is acceptable but at 400ms, participants begin to experience awkward start/stop audio collisions, especially during a conference, when speakers are more likely to interrupt one another. This condition is often referred to as the walkie-talkie effect. To prevent this and other situations, the underlying network should meet the following guidelines for the basic EV scenarios: EV inbound and outbound PSTN calls measured between the Lync 2013 client and Microsoft data center. EV peer-to-peer Lync 2013 client calls measured between Lync 2013 clients. There are minimum thresholds for customer-managed wide area network (WAN) links transporting EV traffic. The following table lists the minimum and optimal transport qualities for the EV service based on network conditions. Network conditions Minimum quality Optimal quality Interarrival packet jitter (average) 5 ms 2 ms Interarrival packet jitter (maximum) 40 ms 20 ms Packet loss rate (average) 1% 0.5% Network latency Stateless Transport Tunneling (STT) 100 ms 50 ms Table 4 Enterprise Voice traffic thresholds Codec bandwidth requirements Lync 2013 clients use different codecs depending on the calling scenario; the following table helps an IT Admin plan for bandwidth used by a Lync client and to also understand which call scenarios support Lync Media Bypass. 41

42 On Premise SBC Scenarios Caller Callee Codec Table 5 Codec bandwidth requirements ** The default behavior of the Lync client in audio conferences is to use the G.722 codec and to downgrade to the Siren codec in either of the following situations: 1. If a Communicator client is participating in the conference call. Communicator 2007 and 2007 R2 do not support the G.722 codec. 2. If the Lync client detects a network round-trip time of greater than 25ms.
