[Asterisk-Users] H323 Large Scale

[Kanuri, Seshu (Company IT)]

BJ,

What are the codecs you are using? 

If you are not using G729 or G723, do you think you can increase the
throughput if you use compressed codecs ?

What do you think can improve your throughpout?

 Yes. I'm using Asterisk "CVS-v1-0-01/24/05" with asterisk-oh323-0.6.5
compiled in on two GW's with two DS1's doing RBS wink in each box which
then flip the calls to G711ulaw/H.323 back to an Avaya S8700 where the
users are at.

 Using the Varion quad span cards, and the APIC/IO-APIC kernel enabled,
I'm finding that I still can't above about 70 or so ports concurrently
active on a dual xeon 2.8 gHz machine before sound quality starts to
degrade. This doesn't appear to be a CPU issue, but rather one of missed
interrupts either on eth0 or tor2, so I've cut back to 48 and that has
been very, very stable. These 48 ports are pretty much off hook all
through the business day, so for the month, each box will do a little
over 600,000 minutes through it.

Additionally, it would appear that oh323-0.6.5 does have some leaks of
file sockets going on so after a bunch of connects/disconnects, you can
max out your avail fh's. I've resolved this by automagically having *
restart itself via CRON each night at 20 to 4a when there isn't any
utilization.

Aside from the two initial bandaids we had to overcome mentioned above,
the solution has been rock solid since that time.
