2 years ago, I had this problem that recordings would get
badly out of sync. I've never been able to pinpoint the
problem but found that the voip client's "preserve bandwidth during
silence" setting made the problem go away.
But after moving
to a new server, the problem has come back with a vengeance. And
"preserve bandwidth during silence" does not seem to make any difference
at all
The new server runs on vmware - which got me thinking that running on a vm perhaps could cause such a problem?
