No Ringback Issue (using SIP trunk)

Hello,

May I ask for your help?  I am having a "No Ringback" issue with my system.  The call flow is PSTN -> Voice Gateway -> CM 5.1 -> SIP Trunk -> SIP Device.

I already have "progress_ind setup enable 3" command in my voip dial-peers but there's still no ringback.

Thank you.

Post the config of your router... also, is the 'SIP Device' a SIP endpoint phone?

Thank you.  The SIP trunk in CUCM is connected to Microsoft OCS R2 Mediation Server.  So, The call flow is PSTN -> Voice Gateway (H.323) -> CM 5.1 -> SIP Trunk -> Mediation Server -> Office Communicator Client.

Try this command on the dial-peer with problem :

progress_ind alert strip 2

Thank you.  However, "progress_ind alert" command is not available in my dial-peer.  I am using a voip dial-peer pointing to my CUCM servers.

My CUCM server is using version 5.1.3.4109-1 while my 3845 voice gateway is using c3845-ipvoicek9-mz.124-23.bin.

Were you able to find a fix for this issue?  We are experiencing the same problem.

Thank you,

Re: No Ringback Issue (using SIP trunk)

Is your gateway controlled by CM via mgcp?
Post the config and the output of "debug voice ccapi inout" during problematic call.

Regards.
