We have this same issue with one user on her Windows 10 computer. We've checked her cpu/memory usage and they are both very low. She has zero packet loss, 20 ms latency on send and 0 on receive and jitter is 0 on send and 10 ms on receive. Any other ideas on what would cause this delay? She is also logged in on Webex on her iPhone and we've discovered that she can log out of Webex on her iPhone and the delay on calls to her computer go away. However, when she logs back into Webex on her iPhone, the first 1-2 calls on her computer are fine but then a delay begins where she can hear the caller but they can't hear her for about 10 seconds and it slowly gets longer on subsequent calls.
This user is connected to our corporate network with a patch cable and we've checked the network and have no jitter/packet loss. We've checked the stats throughout the day and the network status remains stable. As you mention @dhanley, there should be no relationship between the delay on calls on the computer and her logging out of Webex on her iPhone so we're not sure how they relate. Next steps for us is to pull logs from the port while she's on an active call. Let me know if you have any other suggestions.
