    I'm trying to set up a number from IpKall to point to one extension in 3Cx using Direct SIP calling. I have everything set up as per http://sites.google.com/a/3cx.com/3cx-wiki/documentation/general/sip-dns-configuration

    I'm not using "name" calling at all. I have put my dynamic dns info and the extension number in IpKall, I see the incoming call in the log:

    21:09:12.916 [CM500002]: Unidentified incoming call. Review INVITE and adjust source identification:

    INVITE sip:270@XXXXXX.selfip.info SIP/2.0

    Via: SIP/2.0/UDP 66.54.140.46:5060;branch=z9hG4bK0cfb3994;rport=5060

    Max-Forwards: 70

    Contact: <sip:2534705002@66.54.140.46>

    To: <sip:270@XXXXXX.selfip.info>

    From: "Sumner WA"<sip:2534705002@66.54.140.46>;tag=as21115359

    Call-ID: 4edc39d31c811bba2cf10c5c79cfc582@66.54.140.46

    CSeq: 102 INVITE

    Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO

    21:09:12.916 [CM302001]: Authorization system can not identify source of: SipReq: INVITE 270@XXXXXX.selfip.info tid=0cfb3994 cseq=INVITE contact=2534705002@66.54.140.46 / 102 from(wire)

    3CX just doesn't seem to know how to handle the call. I've put the SIP ID of 270 in that field in the extension and enabled . In the Advanced settings I've enabled Allow calls to external SIP URIs and put in my dyndns address.
    Any idea what it doesn't like about the Invite? It would seen to pretty straight forward to set up. I'm using the last version 7 release.

    Thanks
