[Freeswitch-users] how to handle returned sip 302 dialplan

[Chav Paskov]

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 at z.z.z.z:5000 SIP/2.0^M
Via: SIP/2.0/UDP z.z.z.z:5000;branch=z9hG4bK215b.e6ae7e74.0^M

the reply from  z.z.z.z back is  sip 302

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 at 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.

Any ideas on this matter  will be highly appreciated.
Best Regards
Chav
