SV: [Asterisk-Users] Running 40 active calls (too much för CPU?)

I should add that thease 25 calls where SIP (internal) to Zap (PSTN) calls.

Mvh,
Jan

Hi,

We're running asterisk 1.2.1 on a Dell PowerEdge 600SC (2.4 ghz) server
connected to the PSTN through two E1 pipes to a TE405P. This has been running
just fine for several months...

But yesturday we connected a large number of softphone SIP clients (50) and 25
of these where running simultaneous active calls on the INTERNAL ethernet using
g711 (ulaw). We noticed that the sound was jagged just as if the CPU
couldn't handle 25 calls (?!).

I checked the CPU load and it never went over 55 % and memusage was low too.

Does anyone know what could be the problem? Are there some kind of CPU spikes
that make these cuts in the audio? If so, why on earth can't a 2,4 ghz
processor handle 25 low-quality audio "tracks" on asterisk when I can
run +50 cd-quality audio tracks when producing music?

ANY help and/or comments would be appreciated since this is quite an acute
problem.

Regards,
Jan

SV: [Asterisk-Users] Running 40 active calls (too much för CPU?)

Hello again,

I read this interesting article about the TE405P card. How do I check what
firmware version my card has?
http://astguiclient.blogspot.com/2005/09/digium-405p-v2-review.html ... And how
do I update it if it's an old one?

Regards,
Jan

SV: [Asterisk-Users] Running 40 active calls (too much för CPU?)

Are the phones behind a NAT? What is the processory memory size? Are the E1
channelized?

SV: [Asterisk-Users] Running 40 active calls (too much för CPU?)

Phones are not behind NAT. 
 
Every client is on the same internal network as the asterisk pbx (nothing is
sent through the internet). It's not the network since I tested this by
calling asterisk from an outside phone (cell) and let asterisk play a message
for me. Same "cutting" and "chopping" when many SIP-clients
where active in a call at the same time.
 
Computer RAM is 2 gb.
 
If the E1 is channelized or not I don't actually know. How would I know this
and why would it affect the call quality when many people are in a call at the
same time (same lines work fine with an Ericsson BusinessPhone Exchange)?
 
Thanks!
 
Regards,
Jan

Are the phones behind a NAT? What is the processory memory size? Are the E1
channelized?
