Hey Robert, if your using PRI's you might as well get something solid
state that will aid you in load balancing and act as a primary
aggregation gw, you should look into items such as a REDBRIDGE device.
It will convert your pri's to tdmoe and act as a gateway with failover
settings. You can then simply make yourself two virtual boxes or two
physical app servers that feed from it via ip (rync'ing the
confs/mailboxes).
Thats a quick and dirty method for ya :)

Coming from the Nortel world (well Avaya now) I have integrated an Asterisk
server to all our Meridian PBX systems to support VOIP and interoffice calls
using G729 and it actually works better than the Nortel solution.
Over the next few years we are planning to retire our Nortel PBX systems,
however these system are rock solid from reliability point of view; I have not
had any problems with the Asterisk servers that I setup and they are working
much better than expected. With that said I would like to hear/know about what
people have done to make the asterisk server a high availability solution.
With Nortel large PBX systems you have two CPU cores, two network shelves that
connect to IPE shelves that control the phones.
Can you build something the similar in Asterisk? Can you setup Asterisk on a
Red Hat Cluster?
I would love to setup 2 servers as Core/Gateway servers that only deal with
inbound and outbound connections (not phones)
We have 4 PRI's - I would like to setup 2 PRI's in Gateway 1 and 2 PRI's in Gateway 2,
then a third server "PhoneServer" that all the sets are programmed up on which
then connects to both gateways VIA isolated network (direct connect), that way either of
the gateways can be down for maintenance and you will still receive inbound and outbound
calls. This I feel is pretty simple, but I don't see an easy way to make the PhoneServer
a failover server - Thought using Red Hat Cluster may work.
I like the idea of this setup as I would like to have a fax server and a call
center server each as a separate machine.
Has anyone setup asterisk in this way?
Thanks.
