  I think so, but I'm a little over my head in the details of rtpmap.
Debug on the gateway shows this:

m=audio 32794 RTP/AVP 0
a=rtpmap:0 PCMU/8000
a=rtpmap:97 iLBC/8000
                                                                              
  
Feb  5 17:28:42.477:  Invalid payload value (97) specified in rtpmap 
attribute line
