[Freeswitch-users] Choppy audio when conferencing 4+ participants

[Mundkowsky, Robert]

Just curious, why so many problems with VMs?

I would think most applications need real time clocks that provide consistent valid data?

Bilal,

you might try a larger AWS instance to make sure your are getting 100% of the box; might help some.

can you reproduce the same issue on real hardware?  We’ve seen all kinds of weird timing issues that could account for this running on aws.
