Best options at 200+ calls a month
Once you pass a few calls an hour, the billing model drives the bill. Flat-rate and per-unique-caller plans scale very differently from per-minute ones.

Editorial opinion
At 200 to 300 calls a month, Goodcall, Rosie Scale and Upfirst Pro are the lowest published options in our index, with different feature sets. If your volume is unpredictable or growing quickly, NextPhone's flat rate removes billing risk. Before committing, confirm how each vendor treats spam and very short calls, since that can change your effective volume.
