We are running on two virtual servers, one on Xen, one on VMWare ESX, both have perfect sound quality. We don't have any hardware cards, pure SIP, and had used different codecs, including g711, g723 and g729 with no issues. We have around 10 people concurrently using the system.
With that said, Jim you have a point, Windows is not the best host for virtualization. Both our environments are based on Linux. -----Original Message----- From: Jim Van Meggelen [mailto:[EMAIL PROTECTED] Sent: Saturday, November 10, 2007 10:53 AM To: 'Asterisk Mailing' Subject: RE: [on-asterisk] Running under Virtual PC.,, What you are proposing might work as a development system (I'll admit that I have not used Virtual PC, but I use VMWare extensively), but regardless, you would not want to put such a system into production. Asterisk requires priority access to the CPU, and as such, it is hard to imagine any kind of virtual machine being able to run it in a manner that delivered proper sound quality. The Asterisk software will actually run well-enough, but the sound quality is going to be poor, even on a powerful system with the Virtual machine running at high priority. Even if it could be tuned to deliver proper sound quality, you would still never be able to predict when some windows background task would steal a bunch of resources. Windows likes to go off and do its own thing, and when it decides to perform some background task, it is quite capable of hogging resources such that your asterisk system will deliver terrible sound quality. If you want a low-cost platform on which to run a small asterisk system, look to something like the Linksys WRT54GL (OpenWRT). If you need FXO, grab something like a Linksys SPA3001. You'll be able to run a phone or two on that with no problems. Virtual machines are awesome for development; asterisk runs perfectly. Unfortunately, the sound quality is generally terrible. Not such a problem in the lab, but a show-stopper in production. Jim -- Jim Van Meggelen [EMAIL PROTECTED] http://www.oreillynet.com/pub/au/2177 "A child is the ultimate startup, and I have three.
