Hey Ron, What you are referring to is totally dependant
on the phone registration time (read: the phone itself [manufacturer]). I
have Cisco phones that re-register in 30 seconds regardless of original
registration server presence and I have Polycom phones that register every 5
min, only if the original registration server is NOT there. I have been fighting this issue but have
not come up with a viable solution just yet. If I reduce the registration
time, to say, 10 seconds, some phones will not be able to do this (Polycom).
Others, like the Cisco will initiate a lot of un-wanted network traffic every
10 seconds. It’s not so much an issue of when a
server fails and the phone can not make outbound calls, the phone will immediately
send traffic to a backup proxy if a user wants to make a call during the
registration cycle and server failure as long as the phone has a backup proxy
specified. The real issue is when a registration server fails, inbound
calls to any phone registered on the server will not be processed (maybe
voicemail) until the phones re-register to another registration server and
their route becomes available within the cluster again. I have not tried SER, only because a lot of
my clients use IAX and this network will be complicated enough without having
to manage 2 different registration systems, SER for SIP and Asterisk for
IAX. I will pound this issue until I find the answer or realize it just
can not be done with Asterisk. I am struggling with this but would like
suggestions. JR From: Ron McCarthy
