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.
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...
Solved! Go to Solution.
Try adding "voice call send-alert" to your CUCM dial-peers. It's supposed to be able to convert a progress message with a progress indicator to an alerting message which should result in a 180 Ringing being sent to CUCM. In that scenario, the phones would play the ringback themselves.
You might want to try enabling all of the codecs under the IPVMS service parameters if you haven't done so already. Will probably need to see CallManager traces to see what is going on with the annunciator allocation.
Thanks for the answer, I checked and enable all the service but the problem is still there (maybe a service to restart to apply the change ??).
I will now go through the logs but which logs are the more specifics for the annunciator?
Hello Hervé ,
Sorry for delay in reply .Your call flow is like this as per traces..
10.175.0.6 --> 10.161.10.170 --> 10.161.10.171 --->10.175.0.6
Now the call is going out from 10.161.10.171(SUB i guess) to 10.175.0.6 , then its a responsibility of SYST_CUCM2_ANN to provide ringback. But there is no annunciator is invoking in this call leg. Can you please recheck the MRGLs are they containing ANN ?
And one more thing , try setting up CFA to an internal number and then check the behavior.
rate all helpful post
Trunk has DEBHO_MRGL
and then the SYST_ANN_MRG contains:
and both ANN are registerd.
I test this morning and it works fine if I forward to an internal number
