Thanks for helping. I do appreciate it.
This is why I really l don't like this model of support. I'm a customer/owner/user and can't get access to the tools I want to use. What does it take to become a certified technician?
You must be sponsored by an authorized dealer, and go to the certification class and pass... Better to just get them to download it for you and give it to you.
I'm not sure that the phone system stats are the most useful measurements. The phone system can't see how the packets are prioritised on the network.
On Cisco switches for example, after setting up each new site for one organisation, I recall my testing step included getting a call up site-to-site, recording subjective testing, then after hanging up doing a "show mls qos stats" on the switch on each site to see that the voice packets had been sent to the priority queue and the non-voice packets had been sent in queue 0.
Do you have a general description of the problem being experienced?
We use the show mls qos stats command and it does show that the packets are being queued to the priority properly and not dropped by the switch.
However if the packet was "lost" after leaving the switch (such as a dirty fiber connection) this would not show up in the show mls qos stats. However it would be shown as missing by something keeping track of the packet stream, such as a phone. The phone then sends the stats to a logging device like the Mitel (Voice Quality Statistics report) or alternatively the IP Phone Analyzer server.
We do get drops on some calls. Some may be due to qos. Some may not.
