Requirement: you can sign up without a sales call, the price is published, and the setup score is 6.5 or higher, so no developer is needed. Bland AI (7.4) ranks above Goodcall in the full ranking and Vapi (7.2) sits just below it; both miss the setup bar: Bland's entry plan is labeled for developers11, and Vapi's function calling needs your own server12. Dialpad and Synthflow sell through sales1314.
