[Asterisk-Users] Asterisk Dynamic DNS

[Roger Hill]

Hope this helps.

I had a similar problem today, when I changed the machine that my single 
installation of Asterisk runs on, but keeping the same IP address. My 
Sipura ATA took about 10 minutes to pick up the new machine (even though 
the IP address had not changed). I deduced that it needed the 
registration to time out before it did the lookup again, and thus reset 
the ARP cache.

So, try changing the registration time out to something shorter...say 5 
minutes or so, see if that helps.
