[VoiceOps] Key System Using Polycom VVX

SLA/SCA functionality, if that's what desired, on the VVX line is spotty at
best and is not supported at all on Asterisk/Switchvox, at least not in the
way your users will likely expect.  At worst, it just simply doesn't work.
 Not to mention that the VVX phone performance has been... let's call it
"questionable," to put it mildly.  We've deployed many hundreds of them and
we see pretty consistent complaints about laggy touchscreen performance and
we get random reboots followed by core dumps from the phones on our
provisioning infrastructure dozens of times every week.  If you're looking
for key system features and thinking of using the VVX expansions, they
barely work (and ONLY on the latest 5.x software), and really don't work as
advertised with provisioning.

If "true" SCA/SLA type functionality is a must, you're pretty much stuck
with Linksys SPA, Snom, or legacy Polycom Soundpoint lines on a
Broadsoft-based switch.  Of course, there's almost no real need for the key
system if people are willing to holistically look at how they use the
phones, but that's a whole different batle...

Just my $.02.
