Hello, I'm testing with OpenSER 1.3.x revision 4393 with RTPProxy. I'm trying to make a call from a Nokia E51 to a SIPp instance started with: sipp -sn uas -p 6060 -mp 4000
The INVITE goes thru OpenSER to SIPp and then, SIPp replies with this: SIPp to OpenSER: SIP/2.0 200 OK Via: SIP/2.0/UDP 210.126.5.158;branch=z9hG4bK9c1e.f06224f3.0, SIP/2.0/UDP 192.168.0.4:5060;received=123.224.149.169 ;branch=z9hG4bK5j85u8aa6jpebhelr55b8bj;rport=64351 From: <sip:[EMAIL PROTECTED] <[EMAIL PROTECTED]> >;tag=r5hbkuj8mlhc6o184cms To: <sip:[EMAIL PROTECTED] <[EMAIL PROTECTED]> ;user=phone>;tag=28909SIPpTag013 Call-ID: nLPxHi_hoIf-POcJ7OKojntw2wgQle CSeq: 7342 INVITE Contact: <sip:192.168.88.16:6060;transport=UDP> Content-Type: application/sdp Content-Length: 135 v=0 o=user1 53655765 2353687637 IN IP4 192.168.88.16 s=- c=IN IP4 192.168.88.16 t=0 0 m=audio 4000 RTP/AVP 0 a=rtpmap:0 PCMU/8000 But when OpenSER relays this to E51, I can see it is adding "a=nortpproxy:yes" immediatelly after the the last characters in the SDP instead of prepending a CRLF.

I believe this is a bug in OpenSER. Thanks, Takeshi
