Common questions
Can I customize my AI receptionist's greeting and tone?
Yes. LobbyStack lets you customize the greeting, tone, business instructions, and call handling rules so your AI receptionist sounds aligned with your brand.
What happens when a caller asks something unusual?
You define the fallback behavior. LobbyStack can take a message for your team or transfer the caller to a person.
Can LobbyStack book appointments directly into my calendar?
Yes. LobbyStack can check availability, offer appointment times, book the appointment, and send confirmation details to the caller.
Can the AI receptionist send a call summary to my phone?
Yes. LobbyStack emails you after each call with the caller's details, reason for calling, outcome, and next step. 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. Complex negotiations, sensitive situations, urgent cases, and specialized troubleshooting can be transferred 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 starts free with 30 voice minutes per month for browser test calls. Paid plans begin at $30 per month for Starter and $100 per month for Pro, with usage-based overages. Enterprise pricing is available for 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, can book appointments during the call, and sends your team a summary with context instead of a raw message.
