Voice Breakage


Im using Asterisk server 1.2 with Predictive dialler (VICIDIAL) using sip Trunk with 2MB Link.
im having problem with voice breakage and voice Destortion also I am using 3 way call as i leave 3 way other 2 callers are also disconnected my requirements are when i left 3 way call they remain on call and talk with each others
im using IBM Systemx 3200 machine with 1GB Ram and im using CentOS 5.

Can any one help me.

VOIP is just as reliant on the quality of the network link as the ‘size’ of it.

Is it possible to see if you’re getting any packet loss or high latency using something like mtr?
