[Freeswitch-users] Bad sound quality and Abnormally large timer gap 100953 detected!

[Sam]

I run Asterisk on a virtual machine and it runs quite well even with approximately 50 to 60 simultaneous callers and tha'ts even with media passing thru it.

No, it's never "safe" (not for production at least) to run VoIP on virtual machines. The reason for better results yesterday was probably because the hardware had less total load by that time, so the problem is probably both the virtual machine, plus the hardware has too much load on it.

You can't count on the time keeping of a vps.

Use windows directly on real hardware, not a virtual machine.
