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

[Danny Nicholas]

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.

Subject: [asterisk-users] 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.
