[Asterisk-Dev] H323 processing limit<BR><BR></FONT></DIV><BR>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><BR><BR>Jeremy McNamara<BR><BR><BR>Xara Developement wrote:<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>

<DIV>Thank you.</DIV>
