You have interesting numbers.
To make those rates, you are billing on 3,125 and 3,000 minutes in a month. That is a third of the actual working minutes for any month in 2020.
And unless I buy more than one line, I’m paying full retail at $0.009 for your “burst” rate anyway. VoIP.ms is not one of the best solutions out there for pricing. There are certainly more economical solutions, especially for partner programs. VoIP.ms is simply an easy retail per minute solution with public pricing.
So based on actual working minutes in a month, the rate for a single ClearlyIP trunk is this.
If I buy one of your trunks and use it for 10,000 minutes, one call at a time, in a month will you still charge only $18?
Oh, and does theat include inbound toll-free?
