Even at level 0, you can initiate a Zoom call from within an order from one of your gigs. Zoom's integrated into Fiverr's system, but I've found the client doesn't get the invitation when you start the session by pressing that button. So, what I do is press that button, then copy paste the invitation link from the session into the order chat for the client.
This option doesn't integrate with your Google calendar like the consultation option does, though.
I've also found the actual Fiverr consultation you aren't qualified to offer to be wonky. I cannot remember what else about didn't work right, and there was more, but you can't even make a proper description of the service with the 100-something or so character limit.
