Hi thecompnerd,
I would be really interested to hear from those who have successfully measured sites with bad wireless voice calls with any of the wireless parameters as well (be it the channel utilization, retransmit etc). Kindly share your experience if any.
Here is a few questions that is not clear for your network environment:
1) Does your network have proper (bidrectional) QoS enabled in the Wide Area Network (WAN) working?
- This will make sure that the problem that you are seeing is coming from the WAN or WLAN.
2) Are you able to split the number of call from the LYNC reporting (one for wired call and another for Wireless calls)?
- Being able to split the bad calls for a site for clients connected to Wired or Wireless will tell you if it's a problem isolated to Wired or Wireless or both.
3) Are your laptop clients configured to do the QoS marking using GPO policies so that the voice packets are being marked correctly when it leave the end device laptop?
- I won't even touch QoS until I have a good grip on how many good call and bad call for a site to see the effect of activating QoS. Maybe that's just me.
