Pat,
A common issue I see (in general) when using multiple VoIP applications is applications NOT releasing devices. For example, one application may use and NOT release a device until that application is closed (not simply minimized) I would recommend making sure ALL VoIP applications are closed (aka not running) and then start the video connection.
Another issue is with the new MAC software permission may need to be explicitly given to the application to access the device.
I hesitate to ask ask, did you enable the proper mic in the application?
As always reach out to our Support Department for any support issues or questions.
