asterisk users - Jan 2013 - Annoying delay after main server goes down

Hello,

we have distributed lots of cisco spa303 IP phones and get them work with
Asterisk. I have configured proxy and alternate proxy and enabled "dual
registration" features in provisioning files(xml files). All phones are
able to subscribe to both of servers. But the problem is, if main server
goes down, i am obliged to wait nearly 20 second in order to place a call
over second server. How to get alternate proxy work immediately after first
server fails ? Thanks in advance.

I think this is a ?phone problem? not an ?asterisk? one.  In my experience a
SIP (IP) phone takes about 20 seconds to properly negotiate (re)registration
(longer for Polycom 501?s).  The best work-around I could recommend would be
to have an intermediate interface like kamailio (sp) that handles the dual
registration.

I think the failover time will be related to the the registration expiry
setting in the phones.

I would suggest to use linux ha and use same ip, which can failover to
second standby server using heartbeat.

This activity takes less then 5secs.
