[asterisk-users] Annoying delay after main server goes down

[Onur Cem Çelebi]

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.
