Hello, I've got simple problem. My ITSP, when sends me an INVITE message, puts a destination DID (e.g. 223517864, 223517865) only in a field 'To:" of the INVITE message. So it looks like: --------------------------------------------------------------------------------------------------------------------------------------------------- Session Initiation Protocol Request-Line: INVITE sip:alamakota@[.....deleted.......];transport=udp;line=eccbc87e SIP/2.0 Method: INVITE Request-URI: sip:alamakota@ [.....deleted.......];transport=udp;line=eccbc87e [Resent Packet: False] Message Header Via: SIP/2.0/UDP x.x.x.x:5060;branch=z9hG4bKedjaoo2068qhogsrm5o1.1 From: <sip:555555555@appsm.ngn.yyyy.pl<sip%3A555555555@appsm.ngn.yyyy.pl>
;tag=SD3lb8e01-118520006-1280255979518- To: "ab"<sip:*223517864*@yyyyy.pl;line=eccbc87e> Call-ID: SD3lb8e01-b5526ec70ec5846b8f02e61df8d8eb32-aovtv90 CSeq: 177862656 INVITE Contact: <sip:x.x.x.x:5060;transport=udp> Allow: ACK,BYE,CANCEL,INFO,INVITE,OPTIONS,PRACK,REFER,NOTIFY,UPDATE Accept: multipart/mixed,application/media_control+xml,application/sdp Supported: timer Min-SE: 60 Max-Forwards: 9 Content-Type: application/sdp Content-Length: 332 Message Body
In Request-Line there's always the same string (in this case it's alamakota@...........), independently of callee DID. Question is: How to route those calls based on 'To' field (more precisely - based on User Part of the 'To' field) ????? Dialplan with simple condition "destination_number" of course doesn't work.... Is there a solution? (Using Asterisk I'm able to analyse whole INVITE message, substract 'To' field and then route via value in this field...) Thanks for any help -- rniczypo
