[Asterisk-Users] IAX and E1 Call State

[Daniel Bichara]

Hi all,

I am connecting two PBX using two * and IAX2. There is one E1 connected 
to each *. I receive a call from PBX-A and dial to *-B / Zap-g1 (PBX-B). 
If the destination is busy or ring until I put on hook, *-A returns 
normal Call Clear and the PBX-A (attached to *-A) bills the call.

PBX-A <-- E1 --> *-A <-- IAX2 --> *-B <-- E1 --> PBX-B

I search the mailing list and I found some emails about Call Signalling 
and IAX protocol. Could IAX return the correct Call State to E1 attached 
to A?
