Dears, hope you all doing well,
We have this environment (call flow):
ITSP (SIP Trunk) --> CUBE --> CUCM (5001 is AA) --> CUC (Customer Service 0 is a hunt group on CUCM extension number 1888)
We have one way-audio and the call will disconnect after 10-15 seconds when calling to this hunt-group, the weird thing is when I do a "debug ccsip messages" the call will work fine
This is the running config on my CUBE
