I have a setup like this:
At the HQ, there is a CUCM,
At Branch 1, there is a CUCME, also acting as a CUBE. (CME-CUBE)
At Branch 2, there is a CUCME. (BR2-CUCME)
At Branch 3, there is a Voice Gateway having an integration with a 3rd Party PBX (VGW)
CUBE and the VGW is register as H323 Gateways on the CUCM
When Branch 3 call Branch 2, Call Signalling will be H323, from the VGW to CUCM to CME-CUBE to CUCME.
Config for CUCM > Gateway config for the CME-CUBE
Required MTP is unchecked
Wait for Far End Remote TCS is Checked
FastStart is Unchecked
On the CUBE, i have the "Allow connection h323 to h323"
My current issue is that there is no RTP Stream hear on the Phone on the CUCME,
From the CME-CUBE to the CUCME, Calls are possible with RTP Being stream correctly.
If i put the direct dialpeer from VGW to CUCME, it will solve the issue.
However, my setup does not allow me to do that, so I am asking all experts what could be the issue.
How should I troubleshoot with this case,
Is there additional config that i need to add or ???
Can you please attach your branches configuration?
I believe it's a codec issue, but i can't confirm yet.
