Greetings,
I am having an issue with RTP Stream (I assume).
So my setup is:
ITSP->CUBE->CUCM->UCCX
This setup was working before and all of a sudden when I try calling from my mobile phone, the signaling works, the call gets connected but I get no audio whatsoever.
What would be the best way to troubleshoot this issue?
I would greatly appreciate your responses and help.
Kind regards,
Ermir.

Both Side not able to hear or just one side ? I Would start checking the reachability first.

Hi!
So the problem is that the IP Phone is on a remote office, I try calling again from my mobile phone and check the show rtp commands and this is what I get:

So I can see the TX: on the leg to ITSP not changing and the RX: on the leg to the CUCM no changing.
