The checks that matter
Can it greet with your name and your real open or closed status. Can it answer only from notes you control. Can it take a message with a callback number. Can it transfer to a person or a department when you say it may, and refuse the transfer when the office is shut. Can a later question stay on the same business for the whole call.
Ask to hear it say 'I don't have that.' If the demo fills silence with a confident invention, it will do that to your customers.
Everything else is a connection
Scheduling, texts, email, a kitchen ticket, a CRM note. Those are useful when the phone call has already done its job. They are not a substitute for a locked script and a knowledge note you can edit. Prefer a service that tells you what is ready now and what still needs a connection.
