Most tenants stores answer every call manually — reservations, hours, directions, "is the kitchen still open?" A 3CX Digital Receptionist handles all of it without a person.
The Call Handling Problem
Every inbound call that needs a staff member to stop what they're doing has a cost. For a tenant during a dinner rush, that cost is real: interrupted service, slower order flow, and customer experience friction. 3CX's Digital Receptionist (IVR) and AI Receptionist automate the entire inbound call flow — routing, answering, and message-taking — 24/7.
How 3CX Handles Calls
Three Levels of Call Automation — Each With a Different Use Case
Level 01: Multi-level menu system. Press 1 for reservations, 2 for hours, 3 for directions, 0 for the host. Set up once, runs indefinitely. Business hours and after-hours routing are separate setups.
Level 02: 3CX V20 Update 8 (Oct 2025) introduced OpenAI-powered AI Receptionist. Callers speak naturally — no keypad needed. AI collects details, routes calls, takes messages in multiple languages. Encrypted, configurable budget.
Level 03: When calls do need a human, ring groups distribute across available staff. Call queues manage peak volume with hold music and estimated wait time. No call goes unanswered during a rush.
📞 What a Tenant IVR Actually Handles Hours and location (most called): recorded message, no staff needed. Reservation requests: routed to host stand or voicemail during peak. Takeout order status: routed to kitchen or Network Devices (computers, Wi-Fi, cameras, and other smart devices) display. Catering inquiries: routed to manager extension or voicemail with callback. After-hours emergency: routed to on-call via mobile. None of these need a staff member to answer a phone during service.
