[asterisk-users] loosing Sipura 841 almost exactly on the hour

[Jim Sturtevant]

I've got a curious situation.  I have a client that is adding a new 
site.  At the moment they have a single 841 at the remote locaiton.  The 
Asterisk PBX is on a public IP simple iptables firewall.

On the remote location where the SPA841 is located they're running a 
Win2003 ISA server as a router/firewall (ugh!).  I would think this is a 
firewall setting, but i can't imagine what it is.  I would also have 
thought the asterisk qualify pings would have kept the connection live.

I have asterisk qualify on, thus the messages below.  

Thanks in advance,
Jim
