You also have to make sure that the Content-Length: header will be adopted when changing the size of the SDP.

Hi,

Can psuedo variables and avpops be enhanced to include the headers in

the SDP message body?

v=0. o=2139869454 25762964 25762964 IN IP4 192.168.1.133. s=SDP Session For C&S MoIP. c=IN IP4 64.xx.xxx.xxx t=0 0. m=audio 40000 RTP/AVP 4 0 97. a=rtpmap:4 G723/8000. a=ptime:30. a=rtpmap:0 PCMU/8000. a=ptime:20. a=rtpmap:97 telephone-event/8000. m=video 40002 RTP/AVP 34. a=rtpmap:34 H263/90000.

Example, what if i wanted to take the local IP of a SIP phone in the

'o=' line and subst it in the 'c=' line for 2 stun enabled clients residing behind the same NAT? Currently I can sort of do this by grabbing the local IP off the call-id header in REGISTER and storing it in the database then regex'ing the IP out of the header with avp_subst. Though this still does not seem to work even with the output from ngrep looking proper. What is cuasing this? I dont see why i should have to store this value in the DB. Subst doenst work multiline so i cant do this in one textops subst call either.

    ## In REGISTER
    ## Save to DB the private IP parsed out of call-id header

avp_write("$hdr[call-id]","i:222");

    avp_subst("i:222", "/.*@(.*)$/\1/");
    avp_db_store("$from","i:222");

    #In INVITE
    #restore pre-stun IP
     if( !nat_uac_test("8") ) {
          avp_db_load("$from","i:222");
          subst( '/^c=(.*)IP4 (.*)/c=\1IP4 $avp(i:222)\r/' );
     };

Thanks, Sumeet
