[Asterisk-Users] RE: Clustering

[JR Richardson]

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

JR,

This is Ron, the one sho originally started this thread on the mailing list.

Ive been keeping up with all the replies, and it seems like you have it
working, but I hope you can answer a few questions of mine.

The phone gets registered to one server, my question is, if you say "kill"
the server that phone is registered to, would it then automagically attempt
to re register to on one of the other * boxes, or do you know what would
happen. 

I know this can be done, im setting up 3 test boxes this weekend, and am
going to experment, also with SER involved to handle registratiosn, unless I
get * to do it all for me in a efficcinet way.

Any info on this would be great!

Thanks
Ron
