Hi, Chris<br>
<br>
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.<br>
Second tell us about your enviroment:<br>
- Real hardware: the server that will run your vm. ¿Are blades,
small server, etc? VM software used (VMware, OpenVZ, XEN, Jails...)?<br>
- ¿How you set your VM? cpu, cpu cores, memory, disk, #nic?<br>
- ¿How many calls have you handle in the real world?<br>
- ¿Transcoding?<br>
- ¿Have you tested your VM?<br>
<br>
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: <font color="#ff0000">YOU HAVE MAKE A LOAD TEST TO TEST YOUR
ENVIROMENT AND IDENTIFY POSSIBLE ISSUES BEFORE GO TO
PRODUCTION!!!!</font><br>
<br>
Virtualization solutions will do their homework to make VoIP a
secure option. Look this paper for wmware:<br>

<pre>Hi FS Users,
What is the consensus about using virtualized servers for real-time voice (RTP)? Even up until a few years ago it was hard to guarantee the CPU cycles to the voice nodes.
Virtualizing the signalling (SIP) has always been favourable in terms of HA.
If the entire host is under control, is it safe to say - we can virtualise voice?
Does it depend on what else is shared in the host - say it would be silly to put a high load database server on the same hardware node...
Thanks for your inputs
Chris
