Hi all,
I've posted another message yesterday about the same problem. I will try
to be more detailed to get some help from the list:
I am connecting two PBX (PBX-A and PBX-B) using two * (*-A and *-B).
Asterisks are connected via IAX2. The PBXs area connected to each *
using an E1.
PBX-A <-- E1 --> *-A <-- IAX2 --> *-B <-- E1 --> PBX-B
When an extension from PBX-A calls an extension at PBX-B, PBX-A calls
*-A that calls *-B and then PBX-B. The problem is: if extension at B is
busy, *-A returns Normal Call Clear to PBX-A and PBX-A bills the call
normally. I contacted PBX support and they said me *-A should return a
different value to PBX-A (I think it is busy detected).

iax.conf at PBX-A:
[pbxb]
type=friend
auth=md5
secret=secret
bandwidth=low
disallow=all
allow=speex

extensions.conf at PBX-A:
[default]
exten => _.,1,Dial(IAX2/pbxb@192.168.10.2/${EXTEN})
I tried to insert "|r" for ringback-only at Dial command and there is
no
difference.
I search the mailing list and I found some emails about Call Signalling
and IAX protocol.
Any clue?
Daniel
