Creating the Media Termination Instance

Guidelines

The media termination address you configure must meet these requirements:

If you decide to configure a media-termination address on interfaces (rather than using a global
interface), you must configure a media-termination address on at least two interfaces (the inside and
an outside interface) before applying the service policy for the Cisco Intercompany Media Engine
Proxy. Otherwise, you will receive an error message when enabling the proxy with SIP inspection.

Note

Cisco recommends that you configure the media-termination address for the Cisco Intercompany
Media Engine Proxy on interfaces rather than configuring a global media-termination address.

The Cisco Intercompany Media Engine Proxy can use only one type of media termination instance
at a time; for example, you can configure a global media-termination address for all interfaces or
configure a media-termination address for different interfaces. However, you cannot use a global
media-termination address and media-termination addresses configured for each interface at the
same time.

Note

If you change any Cisco Intercompany Media Engine Proxy settings after you create the
media-termination address for the proxy, you must reconfigure the media-termination address by
using the no media-termination

command, and then reconfiguring it as described in this

procedure.
