Cisco Meeting App - Microphone error when not connecting a camera

Good Morning,

we are having some troubles while using CMA since if we connect to a videoconference room without any camera connected to our devices, microphone doesn't work properly and starts a loop - it disconnects and connects repeatedly. The "Join Meeting" button switches from blue - available - to gray - unavailable.

 

We have tried in different devices, laptops and desktop PCs, and all of them have the same error if we disconnect the webcam at hardware level, if we only deactivate it, it works properly.

 

Any ideas of why is this happening?


Thank you.

Users cannot join the call from CMS 3.4 WebApp if only microphone is enabled. Error seen is "Unable to join call" In the browser logs we could see the error "CANNOT_ACCESS_LOCAL_MEDIA".

Symptom: After Upgrade to CMS 3.4 customers cannot connect to WebApp meeting when Mic is enabled and Camera is disabled from control panel/in desktops with no inbuilt camera.

Conditions: CMS 3.4 Camera is disabled or there is no inbuilt camera and external camera attached. Microphone is enabled. Workaround: Revert to version below CMS 3.4
