Phone Systems for Hotels and Restaurants — Teams Phone vs Traditional PBX

The Phone System Decision in Hospitality

Hospitality businesses rely heavily on phones. A hotel's front desk handles reservations, queries, and guest requests around the clock. A restaurant takes bookings, answers questions, and coordinates with suppliers. A venue's event team manages communication across multiple contacts simultaneously.

The traditional answer to business telephony was a PBX — a physical phone system installed on premises, managing extensions, transfers, and voicemail. Many hospitality venues still run on PBX systems installed years ago.

But those systems are aging, their manufacturers are ending support, and a new generation of cloud-based phone solutions has emerged. The most widely adopted in Australian business is Microsoft Teams Phone — part of the Microsoft 365 ecosystem.

What Traditional PBX Offers Hospitality

A traditional PBX has served hospitality well for decades. Its advantages include:

Reliability without internet dependency — a PBX operates locally. If your internet goes down, the phones keep working, provided power is maintained.

Familiar hardware — staff know how to use desk phones. The learning curve for a new PBX system is typically lower than adopting a unified communications platform.

Integration with property management systems — in hotels particularly, PBX systems often integrate with property management software (PMS) to manage room-to-room calls, voicemail-to-room, and billing for external calls.

Cost certainty — once installed, a PBX involves known monthly costs for lines and minimal ongoing IT management for a stable setup.

The disadvantages of traditional PBX are becoming harder to ignore. Hardware maintenance, limited flexibility for remote workers, per-extension costs for expansion, and the eventual end-of-life reality for aging systems.

What Microsoft Teams Phone Offers

Microsoft Teams Phone replaces traditional desk phones with a cloud-based calling system. Calls are made and received through the Teams application on computers, smartphones, or specialised desk phone hardware.

Flexibility — staff can take and make calls from any device, anywhere with an internet connection. For management teams who move between venue and home, or for multi-site operations, this is significant.

Integration with Microsoft 365 — if your team already uses Teams for messaging, the addition of telephony consolidates communication into one platform. Voicemails appear in the same interface as messages and emails.

Scalability — adding a new user is a software change, not a hardware purchase and installation.

Cost structure — Teams Phone is licensed per user monthly, typically lower capital cost than purchasing PBX hardware.

The challenges for hospitality: Teams Phone depends on a reliable internet connection, the interface may require staff training, and PMS integration — critical for hotels — requires additional configuration or middleware.

How to Think About the Decision

For most hospitality venues, the choice is not binary. Several factors should guide the decision.

What does your team actually need? A small cafe with one or two phone lines has different requirements to a hotel managing dozens of extensions across reception, reservations, concierge, and housekeeping.

How stable is your internet? Teams Phone is cloud-dependent. If your venue suffers regular internet outages, the risk to your phone system needs to be managed — potentially through an internet failover solution.

Do you rely on PMS integration? Hotels using property management systems should verify what integration is available before committing to Teams Phone. Some PMS platforms have native Teams integration; others require workarounds.

What is your Microsoft 365 situation? If your staff already uses Microsoft 365, adding Teams Phone is a natural extension. If you are on another platform, the calculus changes.

What is the age of your current PBX? An aging PBX that is approaching end-of-life or requiring expensive maintenance makes a move to cloud telephony more compelling.

The Hybrid Option

Many hospitality venues find a hybrid approach practical. Core reception and operations remain on traditional desk phone hardware (which can often connect to Teams Phone with appropriate hardware adapters), while management and admin staff use Teams Phone on their devices.

This balances the operational familiarity of traditional phones with the flexibility of a modern platform.

Getting Professional Advice

The phone system decision affects daily operations for years. Getting it right requires understanding your specific venue layout, staff workflows, PMS dependencies, and internet reliability.

A qualified IT provider with hospitality experience can assess your situation and recommend an approach that meets your operational needs without disruption. The worst outcome is adopting a new system that your staff cannot use effectively in the middle of a busy service.

Whether you stay with a modernised PBX, move to Teams Phone, or adopt a hybrid approach, the goal is the same — reliable communication that your team can depend on when your venue is at its busiest.
