What features should every hotel phone system have?

When comparing hotel phone services, it helps to look beyond brand names and price tags. The most effective platforms simplify operations, strengthen guest service, and scale easily as your portfolio expands. 

PMS and property management integration

A hotel’s PMS handles everything from reservations to billing. When the phone system connects to it, daily tasks update automatically instead of relying on manual input. The front desk can check in a guest, assign a room extension, and post wake-up calls or room charges with one action.

In practice, PMS integration reduces errors and smooths coordination across departments. Common integrations—such as Micros Opera, Cloudbeds, and RoomRaccoon—enable the following:

• Real-time room status updates after housekeeping or maintenance calls
• Guest billing that reflects calls and minibar charges instantly
• Automated service events like wake-up calls or check-out notifications

Hotels using AVOXI benefit from extended integration that connects PMS with CRM and analytics systems, giving managers a single dashboard to view both guest activity and operational data.

Guest-facing features

Guests will remember how effortless communication felt. A dependable wake-up call or prompt response from room service can make or break their stay. Core functions, such as Do Not Disturb, room-to-room dialing, and wake-up scheduling, are central to attentive service and overall satisfaction.

And today’s travelers expect even more convenience. A report from Oracle Hospitality and Skift found 73% of guests prefer staying in hotels with self-service technology, including communication tools. They want quick, automated ways to contact staff or handle requests independently.

Modern systems build on these expectations by enhancing classic features with multilingual IVR menus, automated concierge tools, and mobile integration. Together, they make service more personal, reduce response times, and lighten staff workload.

Scalability and multi-property support

A hotel chain’s success depends on maintaining consistent communication across all its properties. Without scalable systems, every new location becomes another technical project.

Scalability means your IT team can manage numbers, routing, and analytics from a single location. Instead of installing new hotel PBXs or renegotiating carrier contracts, cloud-based platforms let you expand instantly across countries or brands.

AVOXI supports this growth with coverage in more than 150 countries, offering instant number provisioning and centralized control so hotel groups can unify communication under one provider.

Reliability, failover, and hybrid fallback options

Hotels rely on phones to ensure guest safety, coordinate staff, and respond to emergencies. Downtime isn’t just inconvenient—it’s a service and safety risk.

Failover mechanisms maintain service when a primary connection fails. Hybrid fallback setups, which combine cloud and on-premise links, ensure calls continue through Public Switched Telephone Network (PSTN) lines if the internet drops.

AVOXI’s distributed infrastructure, backed by multiple data centers, delivers always-on reliability, ensuring calls stay connected across all properties.

Voice quality monitoring and diagnostics

Call quality impacts guest perception. Static, lag, or dropped audio reflects poorly on the brand even if the service itself is excellent. Monitoring tools give your IT team visibility into voice performance before issues reach the front desk.

Effective monitoring capabilities include:

• MOS: Track overall call clarity and consistency.
• Jitter and latency reports: Identify where voice data is delayed or unevenly transmitted.
• Packet loss analysis: Detect signal drops that cause partial or missing audio.
• Real-time alerts: Notify IT staff when call quality dips below defined thresholds.

AVOXI’s Call Insights takes it a step further by transforming these metrics into visual dashboards and trend reports, helping hotels monitor quality across all properties instead of reacting to single-site complaints.

Deployment model: Cloud vs. hybrid vs. on-premise

Not every hotel has the same IT capacity or infrastructure. Cloud systems are well-suited for most hotels due to their scalability and ease of management. Hybrid models bridge existing PBXs with cloud flexibility, while full-on-premise setups serve large resorts that need in-house IT control.

Cloud remains the preferred choice for simplicity and predictable costs, while hybrid provides a safe path toward gradual modernization.

Cost and total cost of ownership

The upfront price doesn’t always reflect the final or ongoing cost. Evaluating the total cost of ownership (TCO) reveals the actual cost of a system over time, encompassing hardware, maintenance, licensing, and IT labor.

Legacy PBX systems require a significant upfront capital investment and have unpredictable service fees, while cloud deployments operate on predictable monthly costs. A typical on-premise setup can cost approximately $15,000–$30,000 per property, compared to about $25 per user per month for cloud alternatives.

Additional cost savings also come from vendor consolidation, faster provisioning, and fewer regional contracts. Global providers like AVOXI make these savings tangible by standardizing communication across countries and reducing administrative overhead.

Security, compliance, and telecom regulations

Security is more than a technical requirement: It protects your guests and your reputation. Hotels handle sensitive data, from credit card numbers to personal information, making privacy and compliance essential.

Systems should encrypt voice traffic, restrict access by role, and comply with key telecom regulations and mandates such as:

• E911 (US): Ensure emergency services can identify a guest’s exact room or floor.
• GDPR (Europe): Protect personal data for all guests, regardless of where calls originate.
• Local numbering regulations: Adhere to country-specific carrier and call-routing requirements to avoid service interruptions.

Relying on multiple small carriers can create compliance gaps. A unified global provider like AVOXI ensures consistent, secure communication. It meets international standards with SOC 2 certification, GDPR compliance, and HIPAA readiness, giving hotels confidence that every call is private and compliant.

When should you upgrade your hotel phone system?

Even the most dependable legacy phone system eventually limits performance. Rising maintenance costs, slower guest response times, and outdated hardware often signal the need for modernization. Planning an upgrade proactively prevents service interruptions and helps your staff work more efficiently.

Here are some common reasons to migrate from legacy systems:

Legacy limitations

Legacy PBX systems were once the backbone of hotel communication but now struggle to keep up. They rely on costly, hard-to-maintain infrastructure, and replacement parts are scarcer as technology advances.

Common limitations include:

• High upkeep costs for outdated hardware
• Limited agility for adding features or extensions
• Little to no integration with PMS or CRM platforms

These systems often cost more to maintain than to replace, making upgrading a smarter investment.

Guest experience and staff inefficiencies

Communication delays directly impact guest satisfaction. Missed wake-up calls, unanswered requests, or misrouted calls can leave guests frustrated and staff overwhelmed. When employees rely on manual processes or outdated interfaces, they spend more time troubleshooting than providing excellent service.

Integration gaps

Disconnected systems create extra work and inconsistent data. Without PMS, CRM, or billing integration, staff must repeatedly enter guest information, which increases the risk of errors and obstructs a complete view of guest interactions.

Scalability challenges

As hotels expand, outdated systems often struggle to keep up, and management may adopt its own PBX setup, local carrier contract, and individual maintenance plan for each new property. This fragmented approach slows growth and complicates multi-site management.

Voice quality and reliability failures

Aging infrastructure also affects call clarity and reliability. Frequent drops, echoes, or downtime during maintenance can disrupt communication and compromise safety during emergencies. When these issues become routine, it’s a clear indicator that your system needs an upgrade.

Best practices for upgrading your hotel phone system

Upgrading your hotel phone system doesn’t have to disrupt operations. With a thoughtful plan, you can modernize in phases, maintain excellent guest service, and manage costs effectively. The following best practices can help you transition from legacy setups to modern, cloud-ready communication:

Implement phased migration with legacy coexistence

Most hotels can’t afford downtime, so a gradual migration works better than replacing everything at once. Many properties keep their PBX active while introducing cloud services to select departments or individual hotels first. This approach spreads the costs and allows for testing before a full rollout.

A typical phased plan may include:

• Running the old PBX in parallel while cloud services go live
• Using SIP gateways to temporarily bridge analog and digital systems 
• Migrating low-risk departments first, then expanding to full coverage once performance is validated

AVOXI supports this coexistence approach through managed number porting, multi-country coordination, and scheduled cutovers. Your hotel guests never notice a change, even as your infrastructure evolves behind the scenes.

Decide on hardware reuse vs. full refresh

Many hotels save on costs by reusing analog phones in lobbies or elevators via telephone adapters. Others replace staff devices to unlock advanced features and better audio quality.

Hotels often:

• Keep simple analog phones for guest rooms
• Upgrade front-desk hardware for efficiency
• Replace devices during renovations to manage spending

AVOXI supports both strategies, integrating with legacy systems while offering compatibility with modern VoIP and softphone devices.

Assess your network readiness and plan bandwidth needs

Reliable voice requires a strong network foundation. Cloud and hybrid systems require stable, low-latency connections and proper Quality of Service (QoS) to prioritize calls and ensure seamless communication.

Before migrating, IT teams should:

• Test bandwidth and connection stability
• Verify router QoS capabilities
• Separate guest and staff networks

AVOXI’s Call Insights tool helps validate performance, providing real-time metrics like jitter, latency, and packet loss before and after deployment.

Plan for failover and redundancy

Redundancy safeguards communication in the event of the unexpected. Failover automatically routes calls through backup paths if the primary network fails, keeping front desk and emergency lines active.

Hotels can strengthen reliability by:

• Using two internet providers for failover
• Powering routers and switches with UPS backups
• Hosting systems in multiple data centers to avoid regional outages

AVOXI’s global carrier network and points of presence (PoPs) provide automatic resilience. If one route fails, calls reroute through another region, ensuring seamless communication and guest safety across all properties.

Choose a hospitality-ready global voice partner

A modern hotel phone system works best when paired with a global provider that understands hospitality. The right partner delivers consistent call quality, regulatory compliance, and reliable service across all properties.

By consolidating vendors and managing coverage under a single network, hotels gain simpler operations and faster issue resolution. Unified routing and built-in diagnostics ensure guests experience clear, dependable communication wherever they stay.

AVOXI offers that reach and reliability. With service in over 150 countries, enterprise-grade compliance, and analytics tools like Call Insights, it helps hotels manage voice systems at scale without the added complexity.
