Video via Inter-Cluster Trunk (Non-Gatekeeper Controlled) with Media Termination Point Required

Hi Outthere,

We've tow CUCM Cluster connected via a Inter-Cluster Trunk (Non-Gatekeeper Controlled). We use the Option Media Termination Point Required.

An Cisco IOS Enhanced Software Media Termination Point works on both sides.

For audio-calls everything works fine!

Now we want to use video-call.

The MTP is in passthrough mode.

Regions und Locations are also conigured.

What else do we need and what are the options to troubleshoot it?

Cisco Unified CM Release 5.0 introduced audio transcoding resources  based on Cisco IOS Enhanced Media Termination Point, which are able to  support transcoding the audio stream of a video call while still  supporting the video stream via a pass-through codec. The pass-through  codec is used only for the video stream because the pass-through codec  cannot be used for a stream that requires transcoding. The following  three conditions must all be true for the pass-through codec to be used:

The two endpoint devices have a  matching CODEC capability.

MTP Required is not checked for either endpoint.

All intermediate resource devices (MTPs  and transcoders) support the pass-through codec.
