[Users] VoIP on virtual infrastructure and oVirt in particular

[Gianluca Cecchi]

Hello,
any feedback about VoIP softswitches on virtual servers?
I found this positive whitepaper on VMware web site but it seems
mostly related to Class5 softswitches (intended for work with
end-users):

I would like to know about real experiences and Class4 softswitches
too (used for transit VoIP traffic between carriers).

Thanks in advance,
Gianluca
