Hi, I'm running a ivr script on FS, the call is from a softswitch to extenal sip endpoint of FS. I added two dialplan in public dialplan xml file. as flow: <extension name="ivr_demo2"> <condition field="destination_number" expression="^88888$"> <action application="lua" data="../ivr/test.lua"/> </condition> </extension> <extension name="ivr_demo2"> <condition field="destination_number" expression="^\*114$"> <action application="lua" data="../ivr/test.lua"/> </condition> </extension> Every thing is ok when call to number 88888. but when I call the second number "*114", fs hangup after accept and answer the call, I captured the sip packets and found FS sent a bye packet after answer the call. the cause is "Reason: Q.850;cause=1;text="Unallocated (unassigned) number"". But as the fs console log show, the call is answered and the correct ivr script is runned. Why FS hangup the call? Does somebody have any idea about this problem? ============sip packets=================== ********invite msg from softswitch INVITE sip:*114@10.37.143.6:5060;user=phone SIP/2.0 Contact: <sip:xxxxxxxxx@10.4.35.17:5061> Content-Type: application/sdp To: <sip:*114@10.37.143.6:5060;user=phone> From: xxxxxxxxx<sip:xxxxxxxxx@10.4.35.17:5061 ;user=phone>;tag=949132463135364198E42500 P-Asserted-Identity: <sip:xxxxxxxxx@10.4.35.17:5061;user=phone> Allow: INVITE,ACK,OPTIONS,BYE,CANCEL,REGISTER,INFO,COMET,UPDATE,PRACK,REFER,SUBSCRIBE,NOTIFY,MESSAGE Supported: 100rel,timer,replaces,diversion Expires: 155 Session-Expires: 1800 Min-SE: 90 Call-ID: 01FD10D1BD81400000010690@sip-3 Max-Forwards: 70 CSeq: 1 INVITE Timestamp: 58520 Via: SIP/2.0/UDP 10.4.35.17:5061 ;branch=z9hG4bK5C0F524645A70C943998751419749696 Content-Length: 150 v=0 o=- 54000602557 1258015146 IN IP4 10.4.35.59 s=SDP Data c=IN IP4 10.4.35.59 t=0 0 m=audio 30000 RTP/AVP 8 a=rtpmap:8 PCMA/8000 a=ptime:20 ******FS ack SIP/2.0 100 Trying Via: SIP/2.0/UDP 10.4.35.17:5061 ;branch=z9hG4bK5C0F524645A70C943998751419749696 From: xxxxxxxxx <sip:xxxxxxxxx@10.4.35.17:5061 ;user=phone>;tag=949132463135364198E42500 To: <sip:*114@10.37.143.6:5060;user=phone> Call-ID: 01FD10D1BD81400000010690@sip-3 CSeq: 1 INVITE Timestamp: 58520 0.000000 User-Agent: FreeSWITCH-mod_sofia/1.0.4-14460 Content-Length: 0 *****FS answer the call (in lua script, I called session:answer() ) SIP/2.0 200 OK Via: SIP/2.0/UDP 10.4.35.17:5061 ;branch=z9hG4bK5C0F524645A70C943998751419749696 From: xxxxxxxxx <sip:xxxxxxxxx@10.4.35.17:5061 ;user=phone>;tag=949132463135364198E42500 To: <sip:*114@10.37.143.6:5060;user=phone>;tag=UjZcZUKZXjHcQ Call-ID: 01FD10D1BD81400000010690@sip-3 CSeq: 1 INVITE Contact: <sip:*114@10.37.143.6:5060;transport=udp> User-Agent: FreeSWITCH-mod_sofia/1.0.4-14460 Accept: application/sdp Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, PRACK, MESSAGE, SUBSCRIBE, NOTIFY, REFER, UPDATE, REGISTER, INFO Require: timer Supported: timer, precondition, path, replaces Allow-Events: talk, refer Session-Expires: 1800;refresher=uac Min-SE: 120 Content-Type: application/sdp Content-Disposition: session Content-Length: 245 v=0 o=FreeSWITCH 1257988835 1257988836 IN IP4 10.37.143.6 s=FreeSWITCH c=IN IP4 10.37.143.6 t=0 0 m=audio 24890 RTP/AVP 8 120 a=rtpmap:8 PCMA/8000 a=rtpmap:120 telephone-event/8000 a=fmtp:120 0-16 a=silenceSupp:off - - - - a=ptime:20 ACK sip:*114@10.37.143.6:5060;transport=udp SIP/2.0 CSeq: 1 ACK To: <sip:*114@10.37.143.6:5060;user=phone>;tag=UjZcZUKZXjHcQ From: xxxxxxxxx<sip:xxxxxxxxx@10.4.35.17:5061 ;user=phone>;tag=949132463135364198E42500 Call-ID: 01FD10D1BD81400000010690@sip-3 Max-Forwards: 70 Timestamp: 58520 Via: SIP/2.0/UDP 10.4.35.17:5061 ;branch=z9hG4bK0CC4AE6EE59CA15F69429CDB97848C21 Content-Length: 0 *******FS hangup the call BYE sip:*114@10.37.143.6:5060;transport=udp SIP/2.0 Reason: Q.850;cause=1;text="Unallocated (unassigned) number" To: <sip:*114@10.37.143.6:5060;user=phone>;tag=UjZcZUKZXjHcQ From: xxxxxxxxx<sip:xxxxxxxxx@10.4.35.17:5061 ;user=phone>;tag=949132463135364198E42500 Call-ID: 01FD10D1BD81400000010690@sip-3 Max-Forwards: 70 CSeq: 2 BYE Timestamp: 58521 Via: SIP/2.0/UDP 10.4.35.17:5061 ;branch=z9hG4bKBE2D7D86B44CA171A5D374ECAA99A1DB Content-Length: 0
