asterisk users - Jul 2006 - SV: SV: 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?
