It says it is an assistant
Every call, up front. It never claims to be a person and it never pretends to be you.
This is deliberate and it is not up for negotiation. A caller who works out they were tricked is worse than a caller who knew from the start.
It works out who is calling and what the job is
It asks one thing at a time rather than reading a form at someone. It reads the callback number back digit by digit so you are not chasing a number that was misheard, and if it catches only half a number it asks again instead of saving something useless.
If the caller goes quiet it checks whether they are still there rather than sitting in silence.
It knows your business, and it does not guess
It answers what you do, where you work and the basics, from the details set up for you.
It will not invent a price or make a promise on your behalf. Asked what something costs, it says you will sort a proper price and call back. That is a limit worth having: a made-up number on a first call is worse than no number.
Urgent calls reach you
An emergency is flagged and put through rather than queued behind an ordinary enquiry.
What it does not do
It does not lock a job into your calendar as a fixed appointment. Where calendar checking is switched on, it looks at your real availability during the call and pencils in a provisional morning or afternoon arrival window for you to confirm. You confirm every one. It never commits you to a time you have not agreed to.
If anything fails
The line degrades to text-back. It never degrades to silence. A caller is never left on a dead line, and that rule holds through every part of the system.
