Absolutely. Finding a way to trigger Asterisk to re-register is the trick. You could just set the register interval quite low but its not ideal. > A linux box with either an ip-down script for DSL or an > execute-on-default-gw-change script would handle this pretty easily I think. If you are using an external device then the default gw would not change. I'm wondering if any of these types of devices have a method of signaling when then have failed-over? I'm guessing there may be some that support logging to an external syslog or use SNMP. If so, it would be fairly straight forward to capture those messages and have asterisk re-register. Again, I'm hoping someone on this list has more experience with these types of devices.
