Line Canary Calls Your Business Phone Line Before Customers Do

Field notes

The service models an external caller rather than relying on internal phone-system status: it calls on a schedule, follows a script, records and transcribes the interaction, and checks the observed route against an expected result. The stated free plan covers one line checked daily, while the broader monitoring menu includes toll-free numbers and AI receptionists. A sample alert describes three consecutive failures ending at a full mailbox.
