FAQ

Can I customize my AI receptionist's greeting and tone?
Yes. You set the greeting, tone, business instructions, and call handling rules, so your AI receptionist sounds like your business.

What happens when a caller asks something unusual?
You decide. LobbyStack takes a message for your team or transfers the caller to a person.

Can LobbyStack book appointments directly into my calendar?
Yes. LobbyStack checks availability, offers open times, books the appointment, and texts the caller a confirmation.

Which languages can callers speak?
Callers can talk to LobbyStack in 70+ languages. Each call opens in your default language: English, French, Spanish, Serbian, German, Brazilian Portuguese, Italian, or Dutch. If the caller asks to switch or speaks another language, the receptionist answers in that language.

Can the AI receptionist send a call summary to my phone?
Not after every call. LobbyStack saves a summary of each call in your dashboard. When it takes a message, it sends your team an email alert, and on paid plans you can also turn on SMS alerts.

What types of calls should still go to a human?
LobbyStack is a strong fit for routine questions, bookings, intake, and lead qualification. Transfer complex negotiations, sensitive situations, urgent cases, and specialized troubleshooting to your team.

Yes. LobbyStack is an open-source AI receptionist. You can use LobbyStack Cloud for a hosted setup or self-host the stack when you want more control over infrastructure and customer data.

How much does an AI receptionist cost?
LobbyStack's free plan includes 30 voice minutes and a US or Canadian number for 14 days. Paid plans start at $30 per month for Starter and $100 per month for Pro, with usage-based overages. Enterprise pricing covers higher volume and self-hosted support.

How is LobbyStack different from a call tree or voicemail?
A call tree pushes callers through rigid menus, and voicemail asks them to wait for a callback. LobbyStack answers naturally, uses your business knowledge, books appointments during the call, and saves a summary of each call for your team instead of a raw message.
