[Freeswitch-users] 2012 VoIP With Virtualization

[Saugort Dario Garcia Tovar]

Hi, Chris

That depend of your enviroment. First you have to take a sort of 
scientific approach: define, trial and test again and again until the 
result be consistent.
Second tell us about your enviroment:
     - Real hardware: the server that will run your vm. ¿Are blades, 
small server, etc? VM software used (VMware, OpenVZ, XEN, Jails...)?
     - ¿How you set your VM? cpu, cpu cores, memory, disk, #nic?
     - ¿How many calls have you handle in the real world?
     - ¿Transcoding?
     - ¿Have you tested your VM?

Virtualized enviroment for VoIP are growing. I am consultant for contact 
center services, and I have receive a lot of questions about 
virtualization. A solution provider can give some guidence about sizing 
and technical considerations but at the end the final word is: YOU HAVE 
MAKE A LOAD TEST TO TEST YOUR ENVIROMENT AND IDENTIFY POSSIBLE ISSUES 
BEFORE GO TO PRODUCTION!!!!

Virtualization solutions will  do their homework to make VoIP a secure 
option. Look this paper for wmware:
