Votes held by “voice” are by ‘acclamation’ - ie, the side that shouts the loudest wins the votes. There is no roll call taken unless one is called for.
If you want to see how many of these UN treaties are passed in the Senate, you’ll see that the same tactics are used. Suspended rules, voice vote by acclamation, no roll call.

Precisely. This goes back at least to the 40's.
