Thanks Anca for the explanation, but can you just tell me if what I'm trying to do here is possible with B2BUA or not? if you are saying that A side Refer-to header will be read then obviously I need to take care of the client1 and server1 parameters accordingly.
I've a FreeSwitch as Media-Server to play some IVR to User-A and collect DTMF.OpenSIPS will be acting as B2BUA for this call. Once DTMF are collected, Media-Server Refers the call back to OpenSIPS At OpenSIPS I need to do some accounting on the collected DTMF (I may need more than one XML script to get the control back) If I get OK from AAA then Send INVITE to the DTMF destination else Send INVITE to Media-Server to play some Message.
