No, that's what's puzzling. If anything, the box is overpowered for it's duties (PostgreSQL server, our application services, and Freeswitch.) Over 6GB free memory, less than 10% CPU load, and a gigabit network link on a switch that's got less than 5% utilization. On 19/05/2011 10:45 AM, Avi Marcus wrote:

We've got a FreeSwitch box using a SIP trunk to an Asterisk box, which connects to our T1.

We're having significant voice quality issues, and I'm not sure what to look into. CPU load is under 10% on the Freeswitch box.

Even playing back 8kHz audio files shows significant breakup, so I think I've been on the wrong track thinking it was a SIP issue.
