When you virtualize phone systems it is very common to use an external media gateway for POTS access.
In the Cisco world, you would use a 28xx or 29xx router with some combination of T1, FXO, and FXS cards as a voice gateway. They are not the only vendor of such things either. -- Phil Brutsche p...@optimumdata.com -----Original Message----- From: Ben Scott [mailto:mailvor...@gmail.com] Sent: Tuesday, November 08, 2011 8:52 AM To: NT System Admin Issues Subject: Re: OT - Phone System In A Virtual Machine On Tue, Nov 8, 2011 at 8:56 AM, James Kerr <cluster...@gmail.com> wrote: > I have a desire to run a voice-mail and PBX on virtual machines, if possible. If the phone system requires any special hardware in the PC, it's unlikely to work. For example, expansion cards for interface to analog or TDM ports. For something that's just an Internet Protocol node, it should work. expect vendor support will be the biggest issue. Phone equipment makers often act[1] rather ignorant when it comes to their PC-based platforms. You don't want to end up in a "We don't support that configuration" scenario if your phones are down. From a technical standpoint, it should be fine. OSes are already time-sliced; you're just time-slicing the OS now, too. There may be some tech details to work through. Real-time voice is very susceptible to latency and jitter, so there may be some VM tuning involved there. You prolly don't want to oversubscribe the host resources for that VM. -- Ben [1] "Act", not necessarily "are" ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe ntsysadmin ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe ntsysadmin
