[OpenSIPS-Users] SDP manipulation & rtpengine

[Pat Burke]

Hello:


I am using trying to manipulate parts of the SDP body before calling rtpengine_offer / rtpengine_answer.  However, any changes made via textops functions such as subst_body, replace_body, replace_body_all, etc. do not seem to impact the SDP that is sent to rtpengine.


In my particular case, rtpengine fails to parse the SDP because of an extra carriage return line feed sent in the SDP.  Is there a way to send rtpengine manipulated SDP, rather than just the SDP sent in the request?


Use case:
if (subst_body("/(^a=.*\r\n)\r\n/\1/g")) {
  xlog("L_INFO", "bad SDP --- duplicate CRLF");
}


rtpengine_offer(" ... options ... ");


Regards,
Pat Burke
