One way of using Gruveo to establish a quick video call is to type in some random number, start the call and then pass the direct link to the other party. If that’s how you do it and you don’t care about the particular number used, you can make the whole process even quicker.
Here’s the secret: If you leave the “Number” field empty, Gruveo will generate a random 7-digit number for you. So all you really have to do is go to www.gruveo.com, click “Video call” or “Voice call”, and give the other person the direct link to connect. Now, can it get easier than that?
