I am seeking clarification on the History-Info RFC 4424 In a transit scenario, an incoming call that is immediately redirected to another party, I am getting rejected based on the History-Info field. This is only where there is no A-party identity provided on the initial call. On the outgoing invite I send the from address as 'anonymous@ as.abc.company.com" but include the P-Preferred identity for authentication purposes. My ISP, however will not accept the call based on the fact that the domain in the History-Info is the system IP, and does not match the Server Line/Port on the initial incoming invite. To: "712345678 712345678"<sip: [email protected];url-cookie=VNCHHA1-b6bpj6434lp57<mailto:sip:%[email protected];url-cookie=VNCHHA1-b6bpj6434lp57>>
I do not find anything in the RFC that clearly seems to specify how this should work. 2011-12-21 07:20:20 STS->Network SSP Level = 3 Unique ID = 0 INVITE sip:[email protected]:5060;transport=udp<sip:[email protected]:5060;transport=udp> SIP/2.0 Via: SIP/2.0/UDP 10.XX.YY.ZZ:5060;branch=z9hG4bK2724966256-92170064 Route: <sip:sbc-qld.abc.company.com:5060;transport=udp;lr<sip:sbc-qld.nipt.telstra.com:5060;transport=udp;lr>> Max-Forwards: 25 Authorization: Digest username="NXXXXXXX",realm="client.com",nonce="BroadWorksXgwfexftkTs4w3nmBW",uri="sip:[email protected]:5060<sip:[email protected]:5060>",response="64d5cfk3af388d6016e49ee004a2ab78",algorithm=MD5,cnonce="b3c85b02a0971594cdd55d56653abd6e713a9d8dd7162f62f8a843462fca9350",qop=auth,nc=00000001 Allow: INVITE,BYE,CANCEL,ACK,INFO,PRACK,OPTIONS,SUBSCRIBE,NOTIFY,REFER,REGISTER,UPDATE Supported: timer,replaces From: "Anonymous" <sip:[email protected]>;tag=0_2724896256-92170062 To: <sip:[email protected]<sip:[email protected]>> Call-ID: [email protected]<mailto:[email protected]> CSeq: 3 INVITE Min-SE: 90 Session-Expires: 90;Refresher=uas Contact: "Anonymous" <sip:[email protected]:5060;transport=udp<sip:[email protected]:5060;transport=udp>> P-Preferred-Identity: "712345600" <sip:[email protected]> Diversion: "Spare" <sip:[email protected]<sip:[email protected]>>;reason=unconditional;counter=1 History-Info: "Spare" <sip:[email protected]<sip:[email protected]>>;index=1,<sip:[email protected]<sip:[email protected]>>;index=1.1 User-Agent: Mitel-3300-ICP 10.2.1.13 Content-Type: application/sdp Content-Length: 357 Thanks. _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
