Re: [Serusers] nathelper

Hello: I'm using a NATed UA to terminate a call in the PSTN using a Cisco 5300. I want to use the RTP relay capability. In the script, I wrote: ... force_rtp_proxy(); rewritehost("200.60.XXX.XXX"); forward("200.60.XXX.XXX", 5060); ... Where 200.60.XXX.XXX is the GTW IP. I get an error in the log: "/usr/sbin/ser[7039]: ERROR: extract_mediaip: no 'c=' in SDP" The SIP Message sent to de GTW has a wrong content-length header, so the GTW rejects it. Here I copy the message: INVITE sip:2345674284618@200.60.30.24 SIP/2.0 Record-Route: <sip:2345674284618@200.32.43.55;ftag=673501644;lr=on> Via: SIP/2.0/UDP 200.32.43.55;branch=0 Via: SIP/2.0/UDP 200.68.54.46:5060;rport=25127;branch=z9hG4bKFE5D22D6B6C4407884 2396149F64C3DE From: 1001 <sip:1001@200.32.43.55>;tag=673501644 To: <sip:2345674284618@200.32.43.55> Contact: <sip:1001@200.68.54.46:25127> Call-ID: 107D459F-7402-480D-988A-FC87455E1E5D(a)192.168.0.15 CSeq: 31862 INVITE Max-Forwards: 69 Content-Type: application/sdp voip-gtw04# User-Agent: X-Lite build 1101 Content-Length: 315296 v=0 o=1001 23178458 23178458 IN IP4 200.68.54.46 s=X-Lite c=IN IP4 200.32.43.55 t=0 0 m=audio 35052 RTP/AVP 0 8 3 98 97 101 a=rtpmap:0 pcmu/8000 a=rtpmap:8 pcma/8000 a=rtpmap:3 gsm/8000 a=rtpmap:98 iLBC/8000 a=rtpmap:97 speex/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=direction:active I would appreciate any help about this.
