Frequently Asked Questions

What is an AI voice agent?
An AI voice agent, also called an AI phone agent or AI phone assistant, is software that handles phone calls automatically using artificial intelligence. Zeeg can answer inbound calls automatically, make outbound calls in bulk, understand natural language, and complete tasks like qualifying leads or booking appointments — without a human operator. Zeeg's AI voice agent combines call handling and native appointment scheduling in a single platform.
Can Zeeg's AI voice agent book appointments?
Yes — this is one of Zeeg's core features. During any call, Zeeg detects when a caller wants to book and completes the booking in real time. It checks your availability, offers the caller the possible time slots, and books directly into the right calendar. No callback required. No manual follow-up needed.
How does Zeeg's AI voice agent work?
Zeeg's AI phone assistant connects to your phone number and handles calls based on a conversational flow you define. For inbound calls, it greets callers, identifies their intent, qualifies them, and then acts on the routing rules you've set — booking an appointment, transferring the call to the right team member, or sending an SMS or email. For outbound, you upload a contact list and Zeeg calls each contact automatically, following your script and logging every outcome.
Is Zeeg's AI phone assistant GDPR-compliant?
Yes. All call data and customer information are stored on European servers, and Zeeg is fully GDPR-compliant and made in Germany. Callers are told at the start of every call that they're speaking with an AI, and a data processing agreement (DPA) is available. You also control what's recorded and kept — call recording and transcript & PII storage can be turned on or off per agent, with no conversation data stored unless you choose to. You retain full control over your data at all times.
Does Zeeg support outbound calling?
Yes. Zeeg works as both an AI receptionist (inbound) and an AI outbound caller. You can upload contact lists, define a call goal or script, and Zeeg will work through the list automatically — qualifying leads, delivering messages, or booking appointments.
How long does it take to set up Zeeg AI phone assistant?
Most businesses are live within minutes. You define your call flow, connect your phone number, and Zeeg handles the rest. No developer is required, and no complex configuration is needed.
Can Zeeg's AI voice agent handle calls in multiple languages?
Yes. Zeeg's AI voice agent supports 23 languages, each with a choice of natural-sounding voices. You can define multilingual call flows or let Zeeg automatically detect and match the caller's language.
How much does Zeeg's AI voice agent cost?
You only pay for the minutes you need, and you don't need a paid Zeeg scheduling plan. Booking during the call is always included. Minute packages start at $49 a month for 250 inbound minutes, billed annually; larger packages bring the price down to $0.111 per minute. Or pay as you go from $10: $0.25 per minute inbound and $0.35 per minute outbound.
Which industries is Zeeg's AI voice agent best suited for?
Zeeg's AI voice agent handles calls and bookings automatically across every industry with high call volume or appointment demand: law firms, insurance brokers, accountants, real estate agents, mortgage brokers, recruiters, and more.
What's the difference between an AI voice agent and a traditional IVR?
Traditional IVR systems use rigid menus: “Press 1 for sales, press 2 for support.” An AI voice agent understands natural language — callers just speak normally. Zeeg can follow the conversation, ask follow-up questions, and take meaningful action like booking a meeting, not just transferring a call.
