the call flows is as follow:
SIP Provider=========sip==============CUBE===============sip============IP Phone(SCCP)
SIP Provider=========sip=======CUBE=====sccp=======UCCX===redirect===IP Phone(SCCP)
in first follow i have the ringback.
but in second call i don't have any ringback.
i both follow i did't have and MOH.
I appreciate if someone could help me.
For ringback to be played CUCM needs to select an ANN (announciator) and then send a re-INVITE to the CUBE to play the ring back. In the logs you provided, I do not see the re-INVITE from CUCM to play ringback. I only see an UPDATE indicating the agent extension that the call is now transferred to.
A few things to check:
1. MRGL of the SIP trunk ( this seems okay since calls to phones hear ring back)
2. Localed installed for ANN ( this also looks okay since phone can hear the ring back)
3. I would check the MRGL on UCCX CTI ports.
To get a better picture, can you send CUCM logs including the call details
calling number, called number, agent extension and time of call
Please attach the CUCM SDL logs here
