Not exactly. There are separate rates for IPRelay. The rates we are talking about are for VRS ONLY.
I think the big reason for this is due to Sorenson getting about 85% of the minutes. I mean, think about it. Suppose you want to purchase 100 widgets from a company. The company offers a bulk discount of about 10 cents per widget. If later, you want 1,000 widgets, the company lowers it down to maybe 8 cents. Later on, when you're rich, you might want 100,000 widgets. The company may offer 5 cents.
The point here is that the cost per unit is inversely proportional to the amount of units. Sorenson is getting a metric buttload of minutes, so I think it is fair to get less per minute than if you don't have so many minutes to reimburse.
