[VoiceOps] CPE side Passive Monitoring

Sun Nov 2 12:08:23 EST 2014

Anthony,

So are you saying Adtran's VQM or Edgewaters and everyone elses is really
your embedded engine? I know alot of opensource providers are using
VoIPMonitor as a solution. I believe this software collects stats form
devices like Polycom Phones that use your software.

I have notices that Polycom sells each phone with Voice QM enabled for a
dollar or two more. I assume you need this license to enable stats
collection?
