Hi Pat,

What you can do is to grab the SDP from the msg into a variable, to do whatever fixes/change you have to directly in the variable and push the body via variable to rtpengine.

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 ... ");
