The problem seems to be related to the number of calls being dialed,
and not the number of agents logged in.
Is there any configuration for the Digium cards that would make it work
better? The older server is not crashing with
50+ agents logged in, the load is just high.
We were planning on getting the DS3 card digium is supposed to release
soon. But it seems the problem is dialing 100+ lines
at a time. Will the DS3 card help asterisk handle making the calls? If
not what use is the DS3 card, right?
Today we are going to try Fedora Core 1 x86_64 and Mandriva 2005 x86_64
to see if it works better... Any ideas?

I would say your best bet is to change your system into a distributed
dialing system. We did this with Vicidial and have installations on
multiple servers with over 100 agents all working off of the same
lists and campaigns. A distributed system will also allow for more
redundancy and less total downtime if one server goes down.
We noticed the same kind of limitations you are and now do a max of 40
agents per server, and when we need more capacity we just add another
server.

We are having problems... We use a predictive dialer that we custom
programmed in perl. It basically drops, moves, files into the callout
directory and uses queues to transfer to agents when someone picks up.
Oh, we are running HEAD version.
