Video bonding over T1 PRI

noname2010 · ‎04-10-2010

Hi everyone

my connection like

Tanberg1--------IP--------Gatekeeper---------CUCM----------2811-----------PRI----------PSTN----------Tanberg2

2811 use most recent IOS 12.4(24)T3

the Tanberg1 doesn't have any BRI/PRI on it, IP only, it register with gatekeeper, from Tanberg1 I can make voice call over PSTN, so call routing part is working, the tanberg1 also can call an internal tanberg, all video call over IP is working

furthermore, Tanberg1 can call tanberg2 by bonding 6*B channels, however, as soon as the 6 calls answered, it disconnected immeidately, on tanberg2 I saw the incoming calls, but video never works, the return error code is 47 which indicate invalid resource

You will likely need TAC support and much patience to have this working.

If you want a sure solution, convert tandberg2 to IP.

will ask TAC help

but according the doc, it should work

another thing, convert Tanberg2 is not always possible, we don't necessary control all Tanberg in the world

thanks for your reply

It should, but it's new in 12.4T, and few people uses it in this IP world of today.

Consequently, chances of running into bugs or interop issues are higher than with other features.
