To begin with, open the console and write the command there: "Status".

Now you see all the players on the server and, their serial numbers, find your number.

After that, enter the command in the console: "Callvote kick * your sequence number *", example: "callvote kick 5".

When you do this, voting will begin, all that remains is for your team to vote for the kick.

Congratulations, you kicked yourself.
