The prices listed in our article are actually about right on (within a dollar or two). The tricky thing, is that the advertised prices on RingCentral’s site assume you have multiple users and you pay annually, which is when you get the deal. If you scroll over the little “i” next to each advertised price, you will see a fuller list of pricing for each plan, which is where we got our numbers. Hope that helps! Let us know if you have any more questions.
