Asterisk is sending a 481 in response to an INVITE for reasons I do not understand. Here is the INVITE:
INVITE sip:[email protected]:5060;transport=udp SIP/2.0 Record-Route: <sip:X.YYY.32.10;lr=on;ftag=247898> To: <sip:[email protected] :5060>;tag=ac86f72d2bfe10395b2e62e01c70bf66.0f65 From: "Scott Thompson" <sip:[email protected]>;tag=247898 Via: SIP/2.0/UDP X.YYY.32.10;branch=z9hG4bK542e.5042d534.0 Via: SIP/2.0/UDP X.YYY.33.178:5060;rport=5060;received=X.YYY.33.178;branch=z9hG4bK57b720cccb00f8498662f48e8 Call-ID: [email protected] CSeq: 2 INVITE Contact: <sip:[email protected]:5060> Max-Forwards: 69 x-inin-crn: 2001471530;loc=Amherst;ms=STAMPEDE-MS Supported: join, replaces User-Agent: ININ-TsServer/3.13.11.12748 Allow: ACK, BYE, CANCEL, INFO, INVITE, NOTIFY, OPTIONS, PRACK, REFER, SUBSCRIBE Accept: application/sdp Accept-Encoding: identity Content-Type: application/sdp Content-Length: 252 Proxy-Authorization: Digest username="909003660716",realm="X.YYY.32.10",nonce="5237559000011a22ed0fae66765d46ef9131e311fbb9d2fb",uri="sip:[email protected] :5060",response="cb6306569b3047ac35064dcb5aee6db4" X-Enswitch-RURI: sip:[email protected]:5060 X-Enswitch-Source: X.YYY.33.178:5060 The only problem I see with this INVITE is the VIAs are not right after the INVITE line... although in https://www.ietf.org/rfc/rfc3261.txt, it explicitly states the the order of the headers is not a requirement, it seems Asterisk does make it one... "The relative order of header fields with different field names is not significant. However, it is RECOMMENDED that header fields which are needed for proxy processing (Via, Route, Record-Route, Proxy-Require, Max-Forwards, and Proxy-Authorization, for example) appear towards the top of the message to facilitate rapid parsing. The relative order of header field rows with the same field name is important."
