Configuring trunks in Lync Server 2013
Topic Last Modified: 2012-11-01
As part of Enterprise Voice deployment, you can configure a trunk between a Mediation Server and one or more of the following peers to provide public switched telephone network (PSTN) connectivity for Enterprise Voice clients and devices in your organization:
SIP trunk connection to an Internet telephony service provider (ITSP)
Private branch exchange (PBX)
For details, see Planning for PSTN connectivity in Lync Server 2013 in the Planning documentation.
Before you begin trunk configuration, verify that the topology has been created and that the Mediation Server and its peer have been configured and associated with one another. For details, see Define a gateway in Topology Builder in Lync Server 2013 in the Deployment documentation.
As a part of trunk configuration, you can enable the Lync Server 2013 media bypass feature, which enables media to bypass the Mediation Server. Trunks can be configured either with or without media bypass enabled, but we strongly recommend that you enable it. For details, see Planning for media bypass in Lync Server 2013 in the Planning documentation.
