No ringback over SIP

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...

Try adding "voice call send

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

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.

Hello, Thanks for the answer,

Hello,

 

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?

 

Thanks,

Hello Hervé ,

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.

Trunk has DEBHO_MRGLDEBHO

Trunk has DEBHO_MRGL

DEBHO_MRGL contains:

     - SYST_ANN_MRG

     - SYST_CFB_MRG

     - SYST_MTP_MRG

     - SYST_MOH_UNICAST_MRG

 

and then the SYST_ANN_MRG contains:

     - SYST_CUCM1_ANN

     - SYST_CUCM2_ANN

 

and both ANN are registerd.

 

I test this morning and it works fine if I forward to an internal number

And how about calling from an

And how about calling from an internal number to internal number , whose CFA is set to an outside number ? Thanks Manish

Internally there is no issue,

Internally there is no issue, it's just when an outside call is transfer/forwarded outside.
