[OpenSIPS-Users] SIP SDP rfc1918 address fix

[Satish Patel]

We have some custome Voice solution and in-house media server so right
now i don't care about PORT all i need correct IP address.

I have tried following and it fixed issue but i am seeing following
error in logs

if (method=="INVITE") {
        if(search("^Content-Type:.*application/sdp")) {
        fix_nated_sdp("3");
        };
};


Error:

ERROR: extract_mediaip: no `c=' in SDP
ERROR: extract_mediaip: no `c=' in SDP

Do you know what does that means and how to fix that issue?
