asterisk users - Mar 2009 - question about MeetMe performance.

hello,

 

 

I will do a server to do a lots of conferences (MeetMe).

I want to know that if I dont use a digum card, the limit of simultaneous
calls is harder without a card than with a card ?if, yes, how harder is the
limit?

 

thank you

Maybe upper not harder ? And what card ? (model) If you add just a source of
timing your quality would be better not the limit, there is a transcoding
card sold by digium, and i dont know the possibility of htat card, ask
digium. Anyway the meetme is all about transcoding. Less transcoding => more
conferences. Do your test's!

Hi,

I built a FARM OF ASTERISKs split into 3 
geographically dispersed sites (for high 
aggregate bandwidth concerns).  There were 60 
machines in total.  All of them Dual Xeon 3.0 
with 2GB. [ This turned out to be way more CPU 
that I needed.]   Each machine had 18~24 separate 
conference "rooms".  All rooms were available on 
all 60 machines.  All 60 machines had 18 ~24 
voice feeds (one into each conference.  At peak 
loads every machine also had a maximum of 220 
participants listening - - mixed among the 
different conferences available.  I was listening 
DTMF codes from any listener to allow switching 
from room-to-room.  But no audio allowed from the listeners.

I designed very carefully to avoid any 
trans-coding from the point where the sound was 
first captured - - in the dirver's seat of a 
NASCAR race car.  This was done for several years 
of live races broadcasts with amazing voice 
quality.  At peak we had over 6,000 simultaneous 
callers listening.  There. were no issues on 
Asterisk or SuperMicro machine performance.  I 
had one major foul-up when 18,000 new call 
attempts came in within a 5 minute period and the 
regional telephone system of Southern California 
jammed up and dropped 10,000+ calls before the every reached the Asterisks.

NOT AN URBAN LEGEND.  This was deployed by a team 
of 3 guys using Asterisk 1.4.x in less than 30 
days including purchase  shipping of the 
SuperMicro 1-U machines, configuring the 
Asterisks, deploying to COLO sites, and cross 
connecting (via pre-existing SIP carrier 
gateways) with over 250 Nortel DMS switches in the mobile phone networks.
