Re: Unsupported Media Type, Bayonne2

The sdp negotiation is all in sip/driver.cpp.

At 1506:
 
while(!osip_list_eol(remote_media->a_attributes$ 
         {
                                         attr = (sdp_attribute_t 
*)osip_list_get$                                        if(!attr)
                                                 continue;
                                         tmp = attr->a_att_value;
                                         if(!tmp)
                                                 continue;

                                         if(stricmp(attr->a_att_field, 
"rtpmap"))                                                continue;

                                         adp = tmp;



It parses the remote attributes looking for rtpmap entries.

at 1528, it sees if the map is for telephone-events (2833).

At 1533, it sees if the current map entry matches the media type bayonne 
is looking for (stored in "data_rtpmap").  So if data_rtpmap has invalid 
values, or doesn't match the way the entry is as presented by the 
remote, it will fail to match.  This is where I would suggest looking first.
