[asterisk-users] clustering

[Zeeshan Zakaria]

How about setting up a high availability cluster using DRBD and Heartbeat?
There is some good info on it on the Internet. In this type of setup you
have two exact same servers running in parallel, and only one has the
required services up. They keep themselves in sync. When the primary one
goes down, the secondary instantly takes over. Active calls are though
dropped, but after that everything is back to normal. There are various
other options regarding which server will stay primary, or how and which
services will be used on which server.

Another option I am exploring is using the same thing but in Proxmox with
DRBD. Somebody told me it could be setup so that even the active calls are
not dropped. I haven't set it up yet, but will try it when get time.

Unfortunately we are too late to switch to Kamailio. I mean we have
developed our pbx with call features and routing on asterisk only. If we
switch to some other software that means we will have to redo a lot of
development again. I was thinking of using DUNDi and distributing the
registrations on different servers.



I just dont get one point. lets say if i have 2 users registered on
different asterisk servers and...

Sorry for second post, but I have a Polycom 501 registered to 3 servers.  I
hit the line button and if the server I pick is down, I don’t get a dial
tone.  Hope this is useful.
