[Asterisk-Users] IAX2 insists on not using port 4569??

[Mike Benoit]

For some reason, starting just today, 1 out 3 of my asterisk servers is
having issues calling 1 other server. The only issue I see is that when
it registers with the problem server it is using port 1027, not 4569.

ie:
Registered to 'Server 1', who sees us as 'Server 2':1027

Server 1 then proceeds to timeout trying to register with Server 2.

The way I have each server registering with one another is this:

Server 1 	- Server 2
		- Server 3
*Server 1 is behind NAT, with port 4569 forwarded to it of course.

Server 2	- Server 1
		- Server 3

Server 3	- Server 1
		- Server 2

Now:

Server 1 can call Server 2, and 3
Server 2 can only call Server 3
Server 3 can call Server 1, and 2

So, even though Server 3 registers with Server 1, on port 4569, it can
call it fine (So NAT is obviously working). However Server 2 insists on
registering to Server 1 with port 1027, and it cannot call server 1.

Server 1:
--------------------
*CLI> iax2 show registry
Host                  Username    Perceived             Refresh  State
'Server 2':4569       west       <Unregistered>         60  Timeout
'Server 3':4569       west     'Server 1':4569          60  Registered

Server 2:
--------------------
*CLI> iax2 show registry
Host                  Username    Perceived             Refresh  State
'Server 1':4569       central     'Server 2':1027         60  Registered
'Server 3':4569       central     'Server 2':4569         60  Registered

Server 3:
-------------------
*CLI> iax2 show registry
Host                  Username    Perceived             Refresh  State
'Server 2':4569       east  'Server 3':4569               60  Registered
'Server 1':4569       east  'Server 3':4569               60  Registered


This just started happening today, nothing that I am aware of changed.
All servers are running stock Asterisk v1.0.2. 

Any ideas what would cause Server 2 to just start using some weird port?
