Good morning everybody, I would like to know what would be the best way to process the info in returned back sip 302 message. Let me be a bit more specific. i'm sending INVITE as pasted below to z.z.z.z INVITE sip:17402740539@z.z.z.z:5000 SIP/2.0^M Via: SIP/2.0/UDP z.z.z.z:5000;branch=z9hG4bK215b.e6ae7e74.0^M Via: SIP/2.0/UDP y.y.y.y:5060;branch=z9hG4bKaa6257694041475e0659eeb0019a0bbc^M From: "Bob Caller" <sip:6144102508@y.y.y.y:5060>;tag=CCC7.1F37^M To: <sip:17402740539@x.x.x.x:5060>^M Call-ID: 15821337-3367080415-112396@msc-01.voice.example.net^M CSeq: 1 INVITE^M Contact: <sip:6144102508@y.y.y.y:5060>^M Content-Type: application/sdp^M Max-forwards: 69^M Session-expires: 3600;Refresher=uac^M Supported: timer^M Content-Length: 200^M ^M 1192 v=0^M o=iserver 16123 16124 IN IP4 y.y.y.y^M s=sip call^M c=IN IP4 64.112.188.81^M t=0 0^M m=audio 55824 RTP/AVP 18 0 101^M a=sendrecv^M a=fmtp:101 0-15^M a=rtpmap:101 telephone-event/8000^M a=ptime:20^M the reply from z.z.z.z back is sip 302 SIP/2.0 302 Moved Temporarily^M Via: SIP/2.0/UDP z.z.z.z:5000;branch=z9hG4bK215b.e6ae7e74.0^M Via: SIP/2.0/UDP y.y.y.y:5060;branch=z9hG4bKaa6257694041475e0659eeb0019a0bbc^M From: "Bob Caller" <sip:6144102508@y.y.y.y:5060>;tag=CCC7.1F37^M To: <sip:17402740539@x.x.x.x:5060>;tag=1087415105^M Call-ID: 15821337-3367080415-112396@msc-01.voice.example.net^M CSeq: 1 INVITE^M Contact: <sip:2145551234@64.112.188.84>;npdi^M User-Agent: eXosip/3.1.0^M Content-Length: my question is: Is it possible to send the call to z.z.z.z , receive the SIP 302 , process the data in Contact field and redirect to the new destination contained in Contact: <sip:2145551234@64.112.188.84>;npdi^M without closing the session. i red something about <action application="set" data="continue_on_fail=true"/> but i'm not sure how to use it.

Chav, Once the 302 is received by FreeSWITCH it will follow it to the contact listed in the 302. What else are you needing to do?

Thanks Brian,

probably i should have explained it in more details.
this whole thing started as an attempt to implement lata ocn /local
number portability/ instead of pure per destination routing.
At the moment i have a access to a service provider who does
"dipping" and returns the LATA OCN data associated with any dialed
destination number. it is returned as Contact: and Content-length:
fields in 302 message.

in other words:

1. i'm sending to this provider let say - 2025556666 as a destination
number.
2. they do the dipping and will return to me either the new dest # if
2025556666 has been ported or if it was not
in content-length field they'll send lata, ocn and state and 10 digits
number.
3. once received i have to compare the received lata , ocn and state
date with a compiled rate deck / blended from 5 different vendors/
and pick the lowest rate - effectively building LCR based on LATA OCN
STATE info.

Hope this will help to clear the picture.
Regards
Chav
