Connection quality via remote SIP (outside our network via
internet) can
be terrible (using GSM), though obviously theres a whole bunch of
other
issues there, so I'm focusing just on the internal network and IAX.
Our connectivity to our IAX/PSTN provider is u-law, so should be ok
but
isn't.
What does -p do ?

All,
I've a question on A*k hardware.
I'm running 1.2.18 on a Dell DC051 (Intel(R) Celeron(R) CPU 2.80GHz)
with 512mb RAM.
I'm supporting 60 users (Cisco 7940s each + Xlite PCs).
Call loads are low, max of about 10 simultaneous SIP/IAX calls.
CPU for A*k rarely goes above 2% as I can tell.
Its IP only, no E1/T1 cards present.
However, I get complaints of bad voice quality, especially on IAX2
calls, silences etc.
Can you verify those complaints?
What codec do you use? I hope that ulaw/alaw and not some compressed
codec.
I'm wondering whether or not the machine needs a faster CPU,
something
like a Duo, as I can't find any faults anywhere else that might cause
these blips.
But the 2% CPU usage seems to suggest it shouldn't.
try running asterisk with the option -p
That might be a bit memory light I'd put 1Gb in that box.
Take a look at vmstat and see if it is swapping.
