[asterisk-users] SER Dispatcher Load Balance How-To?

[Aaron Daniel]

Well, it really depends on what he's using the asterisk servers for.  If
it's for voicemail or apps, he'll just have to make sure that certain
apps land on certain servers, and voicemail can be distributed for
various things.  If ser can do what I've heard/read it can do, it can
handle all the basic call functions (i.e. forwarding) for plenty of
calls.  Also, if the asterisk servers are just acting as gateways (i.e.
t1, e1, etc), then they will have no problem handling a load balanced
configuration.

As an fyi, we have two primary call servers, and two gateways that are
basically exact replicas of each other.  If either of the gateways die,
it's almost completely transparent to the users (I say almost because
any calls in progress will be lost due to the loss of a t1 or two).  It
can be done, it's all in how you design it.

If you use the dispatcher, and load balance, there is no guarantee of that, and transfers and forwarding will break.
