Description
We have custom exam web application for proctoring online exams. Online proctoring is done using Zoom for video integration. We are using “Zoom Meeting SDK for web” version 2.10.0.
- 8-10 candidates log into an examination session. Each examination session uses one Zoom meeting Id
- -For each zoom meeting Id we have telephone feature disabled for Audio section.
Error
When the candidate joins the meeting or moved to a break out room we hear echo or resound. The echo might happen at any stage and with any candidate. We could not find any pattern and the behavior is erratic. Also, we found that its not tied to any device. So far we have tested with devices with Windows OS.
Which version?
Zoom Meeting SDK for web - 2.10.0
