I'm trying to set up a 2800 ISR as an H.320 video gateway. The 2800 is registered with H.323 to CM7 and is using an E1 to connect to the PSTN.The idea is that users with VT Advantage as well as a Tandberg VC H323 endpoint can all use the gateway to make video calls over the PSTN.
Tandberg - H323 - CM7 - H323 - 2800 - E1 - PSTN - Tandberg.
So far following the documentation we've managed to get 5 channels that appear to come up but the H323 tandberg just carries on ringing. Has anyone had any success in getting something similar working. All examples tend to refer to a gatekeeper but we shouldn't require one to get this going.
