As part of Enterprise Voice deployment, configure a trunk between a Mediation Server and one or more of the following to provide PSTN connectivity for Enterprise Voice clients and devices in your organization:

For details, see PSTN Connectivity 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 as described in Define a Peer of the Mediation Server for a Site in the Deployment documentation.
As a part of trunk configuration, you can enable the Lync Server 2010 media bypass feature, which allows 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 Media Bypass in the Planning documentation.
