REYNOLDS

Hello,

I recently had a VTC system installed by a contractor. We are having difficulty terminating and initiating video calls.
I have a G3si running Rls 1.1.3. The configuration is as follows:

A PRI from the pbx to a Ascend imux 3000 provisioned for 6 channels the balance are OOS.
From the IMUX to a Tanberg 6000 codec.

I can dial out directly from the IMUX and watch it dial up a bonded 384K connection and the IMUX appears to be happy.
But when i go back to the codec(Tanberg 6000)and try to dial the same call it almost never completely established a call, yet the IMUX shows all 6 channels connected.
On those few occasions i only get voice with no video. and after the call appears to be up i start getting corrupted data messages on my codec. Again i never get any video, but the distant end can see and hear me fine.
I get these same conditions rather i call a loopback number or a actual system.

Because the inter-connect between the pbx and the imux is a PRI is there any special provisioning that needs to take place in the pbx to allow a video call to correctly operate?

Also when i do a list trace to watch the imux dial i only see it seize one member in the outbound trunk-group.
But when i watch the IMUX dial i see it dial all 6 channels.
one at a time until all 6 are bonded together and get a ONLINE status.
Shouldn't i see it grab each trunk member as it dials? Or is the last 5 channels transparent to this trace?
I status the trunk and see all member active.

Also is there any 1-800 number video loopback numbers that are available for testing?

Sorry for rambling.

Any feed back would be greatly apreciated


Thanks,

Greg
