[Freeswitch-users] freeswitch in vmware

[Anthony Minessale]

It was confirmed by 2 people that using it in bridged mode is the problem.
Can you change vmware networking to NAT mode and tell me if it works for you?

I have done as you suggested to fix the clock (ntpd plus clock=pit) and
it seems to work.
The problem of choppiness remain, I'm not sure if bridge network is the
problem because I've tried to connect from other machine to the guest
running freeswitch and the problem is the same.

Thanks to everyone for suggestions so far!
