How we use Twilio
Twilio provides the phone numbers behind our AI phone lines. A call comes in on a Twilio number and is handed to the voice agent; texts go out through the same number.
The actual workflow
- Each phone line has its own number, routed to a voice agent that answers and takes a message.
- A text summary of every call goes to the human who needs it.
- A watcher checks the account balance so a line never goes dead because the prepaid credit ran out.
What it replaced
A personal cell number on everything and a voicemail box nobody checked.
Rough cost for a setup like ours$5–$40/mo for a couple of numbers and light traffic.
List price (Oct 27, 2026)Pay as you go. A US local number is about $1.15/mo, plus per-minute and per-text fees.
Tips
- Start business-texting registration on day one. It is the slowest part of the whole setup.
- Turn on auto-recharge, or watch the balance. A dead line looks like a dead business.
Gotchas
- US business texting needs A2P 10DLC registration, which takes days to weeks and can be rejected.
- Per-minute and per-text fees are small but add up if a bot gets stuck in a loop.
