[asterisk-users] IAX2 - DualServer Problem

[Mustafa Sakalsiz]

Hi,

I have two asterisk servers and I want to make these servers call each
other as they were internal. I have succeeded in one way. Server B can
call Server A without problem, but Server A cannot call Server B.

Here's the iax configuration of servers

Server A:
==================
[ipek]
auth=rsa
context=from-internal
host=XXX.XXX.XXX.XXX
inkeys=ipek
outkey=odtu
peercontext=from-internal
type=friend
username=odtu

Server B:
==================
[odtu]
auth=rsa
context=from-internal
host=YYY.YYY.YYY.YYY
inkeys=odtu
outkey=ipek
peercontext=from-internal
type=friend
username=ipek

When I try to call from A to B, I hear a message saying "All circuits
are busy now, Please try again later", and also here's the iax2 debug
of Server A. I also tried to get debug output of Server B, when A is
calling, but failed. Server B doesn't create any debug output, when A
calls B.

Another issues is, both servers are behind nat, but the UDP 4569 port
is forwarded in each servers. I can connect to the servers with netcat
from outside. Ports are forwarded perfectly.

I am trying to overcome the issue for days, I am in a desperate
situation. Please help me.
