Combining them

Many businesses use an IVR to route callers, an AI assistant to handle out-of-hours enquiries, and a live answering service for overflow during the day. All three can sit on the same number.

Which is best for a small business?

For a sole trader or small team, overflow call answering or an AI assistant usually wins more work than an IVR, because there are not enough people to route between.
