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?
