Users complaining of poor call quality, but call quality dashboard looks good?
Scott Elliott and ivanja:
Our users are still complaining of very poor quality for PSTN calls -- but the dashboard always says calls are "Good" (even though the Advanced > Debug info usually shows inbound call quality MOS around ~2).
We opened a case in the preview portal (#1244446) but heard nothing so far.
Our owner is quite upset, and we're now trying out other VoIP providers. We've tested three thus far (8x8, RingCentral, OnSIP), all of which sound perfect -- so pretty clearly a Skype for Business issue.
MicrosoftAny other metrics which are out of threshold? I would start to capture a wireshark/netmon log and your UCCAPI logs to understand why this is occurring.
how many users are affected?
Effectively all users in our tenant are affected.
Here's a copy of all the Skype for Business Analytics portal logs of a call that a user said was very poor quality:

Not much stands out, other than the RecvListenMOS which is still abysmal. The inbound speech & noise levels are the same -- which seems very bad, but not sure how to fix that.
(Collecting some wireshark logs; our users only use Polycom handsets, so no Skype client logs.)
- ivanjaThat outbound speech level is indeed concerning. However, the inbound looks pretty solid. Other metrics look however, some deviation on the max RTT and Jitter. Was the call bad during the whole session?
Scott Elliott Did you get any resolution to this issue? Or do you happen to have an issue number we can share with our support folks?
The overall quality of this service has been abysmal; it's just not ready for prime time. We're now semi-urgently evaluating other VoIP carriers.
ivanja The whole call was poor quality. :/
