Book the job while the caller is on the line
LobbyStack answers when your team can't, asks what the caller needs, and books an appointment or takes a callback request.
LobbyStack turns missed calls into booked work.
LobbyStack is an AI receptionist for small businesses. It answers your phone, books appointments into your calendar, and sends urgent calls to your team. Use it for every call, or only when you're busy.

Ready when you are
Callers get an answer when your team can't pick up
LobbyStack picks up the calls you miss, so the caller books a time or leaves a message instead of calling the next company.
Send the right calls to your team
LobbyStack handles routine calls and transfers urgent ones to your team. For everything else, it takes a message with the caller's details and reason for calling.
Answer calls and book appointments while you work
LobbyStack covers the four jobs your front desk does on the phone.
Answers your calls
LobbyStack answers all your calls, or only the ones you can't take. It answers questions from your business information in 70+ languages and collects what your team needs to follow up.
Books appointments
Connect Google Calendar, and LobbyStack checks availability, offers open times, books the appointment, and texts the caller a confirmation.
Collects caller details
LobbyStack collects names, contact info, service needs, timing, and next steps so your team can follow up with context.
Transfers when needed
When a customer needs a person, LobbyStack transfers the call or takes a clear message with the caller's details and reason for calling.
Answers from your website and documents
Import your website and upload PDFs, Word documents, and text files. Add your services, hours, and policies in the dashboard, and LobbyStack answers callers with the same details your team uses.
Handle calls the way your best receptionist would
LobbyStack picks up when you can't, books appointments during the call, and hands urgent calls to a person.
A receptionist that picks up when you need it to
Let LobbyStack answer every call, or only step in when your team is busy, after hours, or unable to pick up. It answers several calls at the same time.
Appointments booked without phone tag
LobbyStack offers open times, confirms the appointment, and texts the caller the details.
Human handoff when a call needs it
Transfer urgent or unusual calls to the number you set. The caller's reason and contact details stay in the call's transcript.

Common questions
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.
Is LobbyStack open source?
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.
