[Freeswitch-users] [Freeswitch-dev] VMWare voice quality

[Michael Jerris]

To the contrary, we have had quite good results in virtualized  
environments and you don't really need timing that is that accurate to  
make it work.  We work quite well on amazon EC2 for example.  There  
are 2 issues I know about with vmware, 1 is you need to set a setting  
on the host to extend somewhat sane clocks being available, the second  
is I have seen issues with the bridged network adapter actually  
doubling up all packets causing very strange issues, I suggest not  
using bridged networking if you experience this.
