Unfortunately, it depends on which channel driver your running.
chan_h323 is setup so that you can take advantage of the codec
pass-through feature of Asterisk. We have simulated 125 concurrent
calls setup in random (sub-15 second) intervals, using passthru, on a
500mhz P4 without causing more than a 5 second delay in call setup
time. We have a few separate production systems (single 2.53 ghz, P4,
2gig ram) with running pass-thru and have never had a single compliant
about audio problems, but at this point we've only pushed about 3 T-1s
of concurrent real traffic on any one system.<br>
<br>
Now, if you have to do the actual codec-ing on the machine then you are
going to lose overall number of calls due to the processor time it
takes to encode and decode whatever codec your running. On that same
500mhz P4 test machine, we were able to simulate 45 concurrent calls
using GSM, again without a long delay in call setup time.<br>
<br>
With that other H.323 driver we couldn't make10 concurrent calls work
reliably, so we wrote chan_h323.<br>

<div>Hi.</div>
<div>I need to know aproximately, how many H323 calls coming from a
ethernet 10/100 card , i can manage with Asterisk running on a Pentium
III 750 MHZ machine with Linux RH9.</div>
<div>Any source of bechmarks ?</div>
