Common Questions
What is the difference between an AI answering service and a traditional answering service?
A traditional answering service uses live human operators to answer calls on your behalf, billed by the minute or by the call.

An AI answering service like KaiCalls uses advanced voice AI to answer calls 24/7, starting at just $10/month. AI can handle call spikes without relying on a fixed operator bench, while human services are limited by agent availability.
