[Asterisk-Users] Asterisk Failover without SER

[Aaron Daniel]

On our phones, when you configure a backup proxy, the phone registers 
simultaneously with both servers.  I can do a sip show peers on either 
server and see all the phones on the system.  Not sure if it works for the 
polycoms, which I'm just starting testing on, but works like a charm with 
the Cisco's.  This gives us the redundancy we need with the system, and 
hopefully the Polycoms handle it well.
