[asterisk-users] Need to increase call count

[Dave Bour]

Have you tested the actual throughput on the link?  What's it max out...
What kind of latency are you seeing as it gets loaded.  
Can you do a local call to your own internal network (softphone or
hardphone) as the system gets loaded and play the same file.   Do you
have quality issues.  This will help isolate if it's a network or server
issue.  Shouldn't be a server issue at that load...but never hurts to
look.

Subject: [asterisk-users] Need to increase call count

Hi all.

I've got a project where I need to make outbound calls and play a
prerecorded .wav file to the called number.

So far, I've only been able to make about 15 concurrent calls before the
cound quality gets poor, and I really need to increase this.

I've got QoS configured to prioritize IAX2 traffic above all and my
connection to the Internet is a PtoP 100Mb ethernet link.
(255.255.255.252 subnet mask)

The server is an AMD Athlon(tm) 64 Processor 3400+ with 512Mb of RAM.
The Nic isn't sharing an IRQ with anything else and the CPU never
exceeds 15% utilization.

Any ideas where I can look for improvement?

TIA,
