Just remember that in virtual environments there are plenty of timing
problems. So proxying real-time traffic (video and/or voice) isn't a
desirable target for this kind of environments. Don't wonder if You
start to receive many complains about synchronizations and quality lost
when load increases.

What You can try is to put real-time in a real machine and signaling on
a VM. This will have more chances to work.

Hi Matthew,

GnuGk works fine on virtual servers. I use VMWare a lot to test in
different environments and it also works in the Amazon EC2 cloud. But
as Edson said, beware of timing issues on your RTP traffic.

As for system requirements, your bottle neck will be CPU and network
throughput. As a value to compare with, a dual core Xenon 2GHz that
handles 50 calls at 384kbps gets about 50% CPU load. So you would
probably need about 4 times that CPU power.

Please let us know how your experiments go, so we have another data
point how much power is needed for that kind of load.

Regards,
Jan

Hi Jan and Edison,

Thank you for the information once I have configured up a system I will post the specifications and results of my testing.

Thanks,
Matt
