This topic assumes that you have already configured media bypass for any trunk connections to a peer (an IP-PSTN gateway, an IP-PBX, or a Session Border Controller at an Internet Telephony Service Provider) for a specific site or service for which you want media to bypass the Mediation Server.

This topic also assumes that you have defined all central sites and branch sites in Communications Server Topology Builder in a way that matches the network region, network site, and subnet configuration that you performed according to the steps in “Create or Modify a Network Region”, “Create or Modify a Network Site”, and “Associate a Subnet with a Network Site”. If they do not match, then media bypass will not succeed.

In addition to enabling media bypass for individual trunk connections associated with a peer to the Mediation Server, you must also configure global settings for media bypass. If you use the steps in this topic to configure global settings for media bypass, the assumption is that you have good connectivity between Microsoft Communications Server 2010 endpoints and any peer for which you configured media bypass on the trunk connection.

If you do not have good connectivity between Communications Server endpoints and all peers to the Mediation Server whose respective trunk connections have been enabled for media bypass, you must configure global media bypass settings to use site and region information when employing media bypass. This allows for more fine-grained control over when media bypasses the Mediation Server. To do this, use the steps in Configure Global Settings for Media Bypass and Associate a Subnet with a Network Site instead.

To enable media bypass globally to always bypass the Mediation Server

  1. Open Communications Server Control Panel.

  2. In the left navigation bar, click Network Configuration.

  3. Double-click the Global configuration in the list.

  4. On the Edit Global Setting page, select Turn on media bypass check box.

  5. Click Always bypass.

  6. Click Commit.
