Is there a way to nail up an IP to IP transcode channel through a 2811 without any SIP (or other) signalling using IOS? I'd like to stream IP media through the gateway using test equipment that cannot perform the SIP signalling. The alternative is to hook up a few endpoints, start a sip session to open up the media ports. unplug the endpoints and turn on the test equip to stream the media. However, I'm not sure there is any keep alive that might kill the session after some interval of inactivity.
