All, I'm trying to understand a behavior I'm seeing in setting up a GK-controlled ICT between UCM clusters.
When I place a call across the GK-ICT, the receiving cluster attempts to allocate an MTP for the call. On the trunk: MTP Required is not checked Inbound/Outbound Fast Start are not checked >From reviewing the traces, I see the MediaManager and MediaTerminationPointControl services working to allocate an MTP, so it does not appear to be a transcoding issue. It appears that the software MTP allocation fails and the system allocates a HW transcoder. This is confirmed if I set the regions to all G711. The call still invokes a transcoder, but the streams are both reported as g711u. If I take the transcoders offline, the call completes without the transcoder, with the media stream directly between the two phones, albeit there are supplementary services issues. Is this a function of the GK-ICT in general? Or is the UCM trying to add an MTP for additional capabilities? Any thoughts are welcome while I continue to test. mike
