I have Grandstream 2170 phones setup using primary/secondary outbound proxy. If I stop Freeswitch on one server, I'm able to make outbound calls no problem. Inbound seems to not work. Any tips on making it failover faster? I also have the same issue if I start Freeswitch, I can't seem to get the Grandstream to reregister automatically. I have lowered the register and subscribe expiration to 60, tried to change option Switch Backup Proxy on No Response to yes.
