A very useful feature to check if your audio and video are working properly is to call VSee's call testing service. You can do this by calling firstname.lastname@example.org. This account is in your address book by default.
Sometimes, demo may not be available due to server maintenance and/or updates. In the case that you get a message that demo is busy, just keep trying and eventually, you should be able to get through.
We also suggest you contact our Technical Support team for assistance if the test call is ringing busy consistently, please click here.
