SIP Trunk call to IVR IGC Removed.

[adrianchurchill]

I have an IVR system connected via QSIG. When I try and call into the IVR from a SIP trunk the call appears to answer but there is no audio. Calls from ISDN trunks and internal stations work fine.

I think this is something to do with the IGC removed entry in the trace below:

Any suggestions appreciated.

Can you check that the attached data (DNIS or caller ID) of the call is not being over written by the QSIG trunk? I think your going to have to look at the IVR logs on this one. I think your routing is ok, but your IVR does not know what to do with the call.

Check the public or private numbering is administered for all trunks.
