    Reliability & Failover

    What happens when we have a bad night?

    Honest answer: your phone still rings. CallsAround is built so that dead air is structurally impossible — failover happens at the phone network, below the AI stack.

    Canaries that actually talk to your line

    An answer canary probes each line every few minutes to confirm it picks up. A separate conversational canary calls every 15 minutes and literally asks the agent, "May I speak to a human?" — then checks that the answer is right. It is monitoring the experience, not just the dial tone.

    Carrier-level dead-man failover

    Two consecutive canary failures automatically flip the number to plain carrier forwarding — at the phone network, beneath the AI stack. Even if the entire voice platform were down, calls still route to your fallback number. Detection and route-around happen in under ten minutes.

    One-tap incident bypass

    An incident switchboard in the dashboard lets you flip any single line — or every line at once — to carrier forwarding instantly. You are never waiting on a support ticket to take back control of your phone.

    A public status page

    A live status page shows whether all systems are operational, how many lines are monitored, and the last incident — the same honesty we would want from any service our own phone depends on.
