The sdp_print() function does not include the a=sendrecv as it is considered the default. What you can do is to modify the soa.c source code and include the flag sdp_mode_always as the last parameter to sdp_print() calls, that should do the trick. You can also include a=sendrecv at the session level, I believe, but then it might not work as intended. There probably should be a SOATAG_SDP_FLAGS() etc. that could be used to pass the sdp_parse()/sdp_print() flags to soa. -- Pekka.Pessi mail at nokia.com ------------------------------------------------------------------------------ Register Now & Save for Velocity, the Web Performance & Operations Conference from O'Reilly Media.
