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?
