Hey @multivirtuel ,
Meeting minutes = session time x number of participants.
Example 1. If five (5) end users participate in a 10 minute meeting session through Customer’s application, then fifty (50) total Meeting Session Minutes will be used. Partial minutes used are rounded up.
Example 2. If there are 5 participants for a one hour meeting, it would be `60 minutes x 5 = 300 meeting minutes. So pricing for this (without the 10K free meeting minutes a month) would be 300 x $0.0035 = $1.05.
Does that clear things up? 
Thanks,
Tommy
