Reza, This is a timely post. We just deployed Asterisk (PBX in a Flash) on our ESX 3.5 platform at our Mississauga office. ESXi is just a skinnier version of ESX. It's a bit early to say much about long-term stability, but we've had no problems with Asterisk since deployment. Fingers-crossed. During testing, we found we had choppy/poor quality audio on playback() operations like autoattendant. It wasn't as bad with voicemail messages so we installed native sounds, hoping that avoiding GSM-ULAW transcoding would fix it. It was improved but not great. We applie a kernel patch to resolve timing issues that caused the choppy audio. Now it's smooth as silk. Info on that patch can be found here: http://pbxinaflash.com/vm/ We ran the code exactly as it appears near the bottom of the page. The only other thing we had to do was edit grub.conf to make the new kernel the default one. I imagine that you're looking at a hosted type of application so, unfortunately, I can't tell you much about scaling since we're running only one Asterisk instance and it's the only thing in the high priority resource pool. It doesn't have to contend with any resource-intensive guests on the same machine. We chose VMware a couple of years ago for several reasons not related to Asterisk. Since then I've heard good things about other platforms like VirtualBox and Xen but I have no first hand experience with them. Good luck with your project, Dave --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
