The more you answer people's questions the more calls you will receive.
Unfortunately, I don't know if Clarity has been promoting the platform so much so I haven't see too much activity in the last year or so (but I might be wrong).
In the past (about 2 years) there was a fair amount of calls.
Good luck!
