Dear All, i am facing the problem with one of my customer where i noticed that Record-Route header containing the "ftag" parameter.
INVITE sip:[email protected] SIP/2.0 Record-Route: <sip:79.99.193.141;lr;ftag=4F6C3030343338350007D3E5;vsf=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA--;vst=AAAAAHQEBAMFAAUABwZzAg0deQ4XHwAKAAAKCy4xNDE-;did=9b.dcc08423> Content-Type:application/sdp To:sip:[email protected] From:sip:[email protected];cpc=ordinary;tag=4F6C3030343338350007D3E5 Privacy:none P-Asserted-Identity:sip:[email protected];cpc=ordinary Supported:100rel,timer Expires:120 Date:Thu, 10 Mar 2011 20:02:01 GMT Session-Expires:3600 Min-SE:90 Call-ID:01FF945D4C81400000054AC4@TB004385_VOIP0 CSeq:1 INVITE Route:<sip:79.99.193.141:5060;lr;transport=udp> Max-Forwards:69 Timestamp:512997 User-Agent:TB004385 Contact:sip:[email protected]:5061 Via: SIP/2.0/UDP 79.99.193.141;branch=z9hG4bK1f07.16311b13.0 Via:SIP/2.0/UDP 79.99.193.138:5060 ;received=79.99.193.138;branch=z9hG4bKDD5A2E7439308FCEA1D45366471A437C;rport=5060 Content-Length:344 Now above is my INVITE which is coming from UAC to SBC and my SBC is sending 400 Bad Request to UAC. My doubt is that FTAG is containing the invalid correct hence SBC is unable to understand the nature of this invite hence sending the 400. Could anyone please help me out to understand this? also is there any limit for the character in FTAG?
