This topic assumes that you have already configured media bypass for any trunks 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.

In addition to enabling media bypass for individual trunk connections associated with a peer, you must also enable media bypass globally. Global media bypass settings can either specify that media bypass is always attempted for calls to the PSTN or that media bypass is employed using the mapping of subnets to network sites and regions, similar to what is done by call admission control, another advanced Voice feature. When media bypass and call admission control are both enabled, then the network region, network site, and subnet information that is specified for call admission control is automatically used when determining whether or not to employ media bypass.

This topic describes how to use Communications Server Control Panel and Communications Server Management Shell together to configure global media bypass settings.

When you use these steps to configure media bypass, the assumption is that you have good connectivity between clients and the Mediation Server peer (for example, an IP-PSTN gateway, an IP-PBX, or an SBC at a SIP trunking provider). If there are any bandwidth limitations on the link, media bypass cannot be applied to the call.

Next Steps: Choose Global Media Bypass Settings

After you have enabled media bypass on any trunk connections to a peer for specific sites or services, use the following content to either a) enable media bypass globally, or b) configure media bypass to use site and region information:
