The question is, is it so heavily loaded that freeswitch will be starved of clock cycles or not. Testing it is the only way to see. Even if it is to some extent, things that don't need timing like regular bridged calls will be much more tolerant of some load than things that require more timing like playing sound files or conferences. I would test spinning up a bunch of channels and calling in and listening to a milliwatt tone to see if its clean or not.<o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Mike<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p><div><div><p class=MsoNormal>On Sep 2, 2013, at 2:34 AM, Grant Bagdasarian <<a href="mailto:GB@cm.nl">GB@cm.nl</a>> wrote:<o:p></o:p></p></div><p class=MsoNormal><br><br><o:p></o:p></p><div><div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'>Hello,<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'> <o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'>I’ve been going through some threads about virtualization, some say it works for them, others say it doesn’t.

The FS virtual will also process RTP in default mode. I was hoping if someone had any experience using this setup and could give me some insights on this matter. The FS virtuals will function only as SBC’s, so no complex dial plans, no call recording, no conferencing.
