Hello guys,
I'm actually facing an issue in my IPTel network. When a PSTN user is calling us and if the call is transfered/forwareded he doesn't receive ringback.
Call flow:
PSTN --> SIP Gateway --> CUCM --> Phone 1 --> Forward/Transfer --> Phone 2
I checked the gateway and in each dial-peer pointing to the CUCM I have the command:
- progress_ind setup enable 3
Under the sip configuration, I have a MRGL who contain an annonciator based on doc: http://www.cisco.com/c/en/us/support/docs/voice-unified-communications/unified-communications-manager-version-50/99341-ccm-sip-ringback.html
If someone has an idea...
