Know your phone line works before a customer finds out it doesn’t

How a check works
Line Canary calls your number
A real call over the phone network, from outside your system, on the schedule you pick.
It follows your script
Listen, press keys, or say a phrase to a speech menu or AI receptionist. The whole call is recorded.
The call is checked
The recording is transcribed and compared with what you said should happen, in plain words.
You hear about failures
After the number of failed calls you choose, Line Canary texts or emails you, and again when the line recovers.
