Providing PSTN Connectivity at a Branch Site
Topic Last Modified: 2011-01-25
We recommend using the Microsoft Lync Server 2010, Planning Tool to add branch sites to your topology and to set up your branch-site voice infrastructure.
If you are not using the Planning Tool, use the procedures in the topics in this section, first to add the branch sites and then to set up your voice infrastructure by defining the Internet Protocol/public switched telephone network (PSTN) gateway and/or configuring the SIP trunk (with or without media bypass). Connecting a private branch exchange (PBX) to the branch site is another option.
If you want to provide branch-site resiliency, you must deploy a Survivable Branch Appliance, a Survivable Branch Server, or Microsoft Lync Server 2010 at the branch site. For details, see Deploying a Survivable Branch Appliance or Server or Deploying Lync Server 2010, as appropriate, in the Deployment documentation.
