When the phone rings and you are tied up, how do you handle the overflow? Both Stella and Numa help you capture missed opportunities, but they take very different approaches. Stella acts like a true front-desk employee. She answers calls with a natural voice, collects customer details, and even greets walk-ins if you use her physical kiosk. The other option works behind the scenes as a smart messaging tool. It catches missed calls and immediately texts the caller back to start a chat. You are weighing whether you want a real-time voice answering the phone or a system built around fast text messaging.
