[VoiceOps] CPE side Passive Monitoring

Tue Nov 11 09:57:22 EST 2014

Anthony,

That you for the information. Sounds like you have a solid product to say
the least. We do buy the VQMon license from Polycom on the VVX line,
however I don't beleive we have any server to collect/report on these
metrics at this time. I will look into  SQmediator, but I assume it is too
expensive for our small shop.

My question is can you use a Polycom with the VQM license installed to
report back to something like voipmonitor.org software? Accoring to
Polycom's website:

With Polycom Productivity Suite Application: Voice Quality Monitoring,  IT
Managers can monitor and troubleshoot voice quality issues more quickly.

   - Transmit metrics in real time, or near real time, directly from the
   phone in the standard RTCP-XR (IETF RFC 3611) format
   - Publish metrics using the SIP PUBLISH method

So if VoipMonitor.org supports RTCP-XR or SIP PUBLISH they should be able
to supports stats collected on the Polycom right?

I guess to make this even more complicated, do providers monitor the WAN
CPE router (like an Adtran 908e) in addition to the phones themselves
(Polycom VVX for instance)?
