Keep your phone system.
Kai just takes the work.

  1. Keep your number.

    Nothing to port. Customers dial the number they already have, on the phones you already use.

    Setting up a number in four steps: pick (512) 555-0168, choose rings you first, then Kai, switch on forwarding for the calls you don't pick up, and place a test call. The test call passes and the number is ready.

  2. Your phone rings first.

    Forward only the calls you don’t pick up. Forward-all would send Kai every call and your own phone would stop ringing.

    A call from Maria, (512) 555-0142, rings your phone three times and you can't pick up. Kai picks up for Williams Plumbing, takes down what Maria needs, texts you a summary and saves her as a lead. The call ends answered.

  3. Kai takes the work.

    Kai gets the name, the job, the address and the timing, and answers the common questions.

    A short call with Dave appears line by line. He has a water heater leaking in the garage and wants someone out tomorrow morning. The transcript folds into one line under What they wanted, which drops into a lead card for Dave marked Hot.

  4. You get a text.

    The details land on your phone, ready for you to call back and book the job.

    Hot lead: Dave needs a drain cleared before Tuesday. Kitchen sink, second time this year. Call back today.
