Hello Everyone, We have setup Asterisk HA, basically what we have is: Virtual IP (for asterisk 1 and 2) 192.168.2.6 asterisk1 192.168.2.110 asterisk2 192.168.2.111 mysql 192.168.2.100 Poly IP300 192.168.2.13: The polycom is configured to use whatever machine is running on VIP 192.168.2.6 HA is configured that if ast1 goes down, ast2 takes over the virtual ip. When only one machine is up, the server handles both the incoming and outgoing. When both machines are up, incoming is handled by ast1 and outgoing is handled by ast2? Again, the phone is configured to use the machine that is up and behind the virtual up 192.168.2.6. How is it that the phone even know about 192.168.2.111, which is performing register and outgoing? I have to look over all the configs for hard coded real server ips. Maybe someone has ventured in Asterisk HA? Cheers, Nick.
