Hello.
We are running a CUCM 8.5 cluster and we have a Cisco 2901.
The 2901 is our MTP, CFB and CUBE.
Whenever we put an inbound or outbound PSTN call on hold, there is silence (no bip bip, only silence). Internal calls have no issues with MOH.
We use Software MTP G711a.
We have the same Media Resource Group for both (IP Phones and SIP Trunk)
We are using Unicast
We have check the MTP checkbox on the SIP Trunk page.
We have enabled all G711a, G711u, G729 in the Service Parameter page.
We have all regions with G711
We attach you the configuration in the CUBE.
My version in my 2901 is: Version 15.1(4)M2
When we have the call active (without Hold), we see the next
