I have an IAD 2431 acting as a SIP<>ISDN gateway. I've got it set up so that SIP<>ISDN calls use iLBC on the VoIP side; however, when the VoIP side puts the call on hold, connecting it to our (G.711-only) Music On Hold server, the IAD tears the call down. I've turned on 'debug ccsip media' and grabbed the following log output:
Oct 24 11:32:11.750: //1326/44A678F2800B/SIP/Media/ccsip_api_request_offer: Call has been put on hold

I assume it's line 2 (%HPI-3-FAILED_START) that's the problem here - does this mean I have a misconfiguration somewhere, or is this just broken?
Thanks!
