[Asterisk-Users] Office to Office via IAX2 problems

[asterisk at txpe.net]

I'm going to try and lay out all the relevant information I have here 
in this one post.  I can provide more info if necessary.

ISSUE 1:
Office A routinely looses connection to Office B. When typing IAX2 
Show Peers, it will show as Unreachable. I issue IAX2 Reload and it 
will work again for 1-3 days (haven't narrowed the time down yet). My 
theory is that the DSL at Office2 is changing IP addresses regularly 
and this is the cause of the problem??? This has been going on since 
I set up Office B (2-3 weeks). I never had to touch Office B box. 
Office B seemed to maintain connection, until now (see Issue 2).

ISSUE 2:
Office B will not connect to Office A via IAX2 any more. The command 
IAX2 Show Peers shows Office A as Unreachable. IAX2 Reload won't fix 
it. I even rebooted the box (MS tricks never die). Up until 
yesterday, Office B always remained connected to Office A (or at 
least since I set up Office B - 2-3 weeks ago). Each office has port 
4569 forwarded to its * box. I even moved Office A box into DMZ, no 
help.   Note, Office A extensions can call extensions at Office B.

Here is the log file after I issue IAX2 Reload from Office B box:

I'm an admitted newbie, but this seems (to me) that this may be 
networking/Linux issue and not Asterisk???
