For IT managers planning a room phone replacement, the key question is not just which model to buy today, but how to ensure the investment remains relevant for the next five to seven years. The answer lies in choosing a Cetis hotel telephone Singapore solution that supports SIP, integrates with property management systems (PMS), and offers modular upgrade paths. Singapore-based AV and IPTV integrator Prestige Solutions helps hotels standardise guest room telephones and plan call flows that align with future technology shifts.
Guest room telephones are no longer standalone devices. They are becoming part of a larger in-room IoT ecosystem that includes voice assistants, IPTV, and room controls. By 2026, most new hotel builds in Singapore will specify SIP-based phones as standard, replacing analogue lines entirely. The trend is toward unified communication platforms where the phone is one endpoint among many, managed through a single dashboard. Cetis has been at the forefront of this shift, offering phones that support Power over Ethernet (PoE), HD audio, and programmable function keys. The next generation is expected to include built-in Bluetooth for guest device pairing and enhanced accessibility features such as visual call alerts. For IT managers, this means the phone you install today must be capable of firmware updates and feature additions without hardware replacement.

Three main forces are pushing hotels toward SIP-based telephones: guest expectations, operational savings, and regulatory changes. Guests want one-touch access to services and seamless connectivity with their own devices. Hotels can cut telecom expenses by up to 40% by eliminating analogue lines and using VoIP. Meanwhile, Singapore's IMDA is phasing out PSTN services, making SIP trunking the default for new installations. As of 2026, any hotel installing analogue phones risks being stranded without support within a few years.
Today's travellers expect seamless connectivity. A hotel phone that only makes calls is insufficient; guests want to reach concierge, housekeeping, or room service with a single touch. Meanwhile, hotel operators need phones that integrate with property management and call accounting systems to track usage and reduce costs. The shift to VoIP and SIP allows hotels to eliminate separate phone lines, cutting monthly telecom expenses by up to 40%.
Singapore's push for green buildings and digital connectivity means that new hotels must meet higher energy efficiency standards. PoE phones consume less power than traditional analogue sets and can be centrally managed. Additionally, the Infocomm Media Development Authority (IMDA) has been phasing out legacy PSTN services, making SIP trunking the default choice for new installations.
For IT managers in Singapore, the implications are clear: any phone replacement project started in 2026 should specify SIP-capable devices. Analogue phones will become increasingly difficult to support as telcos retire copper lines. Moreover, hotels that standardise on a single phone model across all room types—from standard rooms to suites—simplify inventory, training, and maintenance. Prestige Solutions recommends a three-phase replacement approach: first, audit current phone inventory and call flow requirements; second, select a Cetis model that matches your property size and feature needs; third, plan a phased rollout during low-occupancy periods. This minimises guest disruption and allows staff to adapt gradually.
Planning a future-ready deployment involves assessing your current infrastructure, choosing the right Cetis model, and mapping call flows. Below is a step-by-step guide.
Before purchasing new phones, evaluate your existing network. Do you have PoE switches? Is your PBX SIP-ready? If not, factor in the cost of upgrading network switches and possibly migrating to a cloud-based PBX. A typical 200-room hotel may require 24-port PoE switches costing around SGD 1,500 each, with two switches per floor.
Cetis offers several series: the basic 100 series for budget-conscious properties, the 200 series with programmable keys, and the 300 series with colour displays and Bluetooth. For a future-proof deployment, the 200 or 300 series is recommended as they support firmware updates and advanced features. As of 2026, the 300 series also includes a USB port for charging guest devices.
| Cetis Series | Key Features | Ideal For |
|---|---|---|
| 100 Series | Basic SIP, fixed keys, no display | Budget hotels, limited-service properties |
| 200 Series | 8 programmable keys, HD audio, PoE | Mid-range hotels, business hotels |
| 300 Series | Colour display, Bluetooth, USB | Luxury hotels, full-service properties |
Work with your integrator to map out call flows: how do guests reach front desk, housekeeping, or room service? Should the phone auto-dial emergency services? Integration with your PMS allows for automatic wake-up calls, do-not-disturb status, and check-out billing. Prestige Solutions can help design these flows and program the phones accordingly.

When planning your budget, consider these cost drivers:
These are broad planning ranges; exact pricing depends on scope and site conditions. Contact Prestige Solutions for a detailed quotation.
A phased replacement timeline helps minimise disruption and allows for testing. Start with a pilot floor to validate call flows and integration. Then roll out to remaining floors during low-occupancy periods. Allow 2-4 weeks for installation and testing per phase. Prestige Solutions can create a timeline tailored to your occupancy schedule and budget.
Begin your replacement project with a site audit and call flow review. Prestige Solutions offers a complimentary consultation for hotels planning a phone upgrade. They will assess your current infrastructure, recommend the appropriate Cetis models, and provide a phased implementation timeline.
