The issue is that if a meeting participant doesn’t have an account and/or doesn’t sign into an account, the device is recorded as “unknown”. I am not sure why this would be since that information must be accessible to the app regardless of how they connect (yes?) . Since that info is missing, a call to :
returns “device”: “Unknown” for all participants. Our implementation doesn’t require that participants sign into an account when joining a meeting, they simply use the meeting ID. So, we have no metrics on what kind of devices folks are using to connect which be a useful metric to have. Our particular use case was to determine what participants use a “call in” option on a mobile device so we can send the meeting ID by text. Trying to determine how many folks use a “phone” device to connect would help us determine the frequency and cost of such an implementation.
The fix is simple: add the correct device type for all participants, whether signed into an account or not.
I tried to find an alternative property that might give me an indication that the participant used a phone call to participate but I couldn’t find a property that would indicate that besides the device type
