Re: [SR-Users] BYE dialog timeout bad syntax

Hello, The BYE, generated by Kamailio in case of dialog timeout, is malformed: /BYE sip:anonymous@192.168.225.2:50601 SIP/2.0/ /Via: SIP/2.0/UDP 172.16.60.113;branch=z9hG4bK77b6.941684b6.0/ /Via: SIP/2.0/UDP 10.1.1.10;branch=z9hG4bKsr-JfymiMenCtp4urS5CXSnCHJnCXJZiHvRCHYJb6ggNPN9NVDL3-TWhdW0UvOfN1KPTReRiHy1CHmcs6mZiHS*/ */To: sip:anonymous;cpc=ordinary@192.168.225.2;tag=01e3a8c0-c1c2-t-1/* /From: sip:1255010006@192.168.225.2:5060;user=phone;tag=813142547-1366730270587/ /CSeq: 465332801 BYE/ /Call-ID: 1aebb42c-01e3a8c0-000007c2(a)192.168.225.2 <mailto:1aebb42c-01e3a8c0-000007c2@192.168.225.2>/ /Content-Length: 0/ /User-Agent: kamailio (3.3.2 (x86_64/linux))/ /Max-Forwards: 69/ The bad syntax is located in the "To" header field. According to the RFC 3261 section 25.1, the grammar of the To header field is as follow: To = ( "To" / "t" ) HCOLON ( name-addr / addr-spec ) *( SEMI to-param ) name-addr = [ display-name ] LAQUOT addr-spec RAQUOT addr-spec = SIP-URI / SIPS-URI / absoluteURI to-param = tag-param / generic-param The RFC 3261 section 20.10 explains that: Even if the "display-name" is empty, the "name-addr" form MUST be used if the "addr-spec" contains a comma, semicolon, or question mark. There may or may not be LWS between the display-name and the "<". As the "addr-spec" */sip:anonymous;cpc=ordinary@192.168.225.2/* contains a semicolon, it means that the "name-addr" form must be used. The "To" header field should be encoded as follow: */To: <sip:anonymous;cpc=ordinary@192.168.225.2>;tag=01e3a8c0-c1c2-t-1/* BR, Julia _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
