i was studying implementation of sdpops/sdp_content() function and noticed that it is heavy, because it parses the whole sdp: static int w_sdp_content(sip_msg_t* msg, char* foo, char *bar) { if(parse_sdp(msg)==0 && msg->body!=NULL) return 1; return -1; } sdp_with_ice(), for example, just searches a string from the body. how about this: - sdp_content() succeeds if content-type is application/sdp and content-length > 0. - sdp_content() succeeds if content-type is multipart/mixed and body has line that includes string "application/sdp". - otherwise sdp_content() fails. -- juha
