For IT managers in Singapore hotels, replacing guest room telephones requires a structured timeline that balances operational continuity, budget cycles, and guest experience. The key is to start planning 6–9 months before the desired cutover, allowing time for site audit, device standardisation, call flow reconfiguration, and phased deployment. This guide walks through the essential steps, from initial assessment to ongoing support, using Cetis hotel telephones supplied by Singapore-based AV and IPTV integrator Prestige Solutions.

The primary goal of a Cetis hotel telephone replacement project is to standardise the guest room phone devices across all room types and to modernise the call flow logic for front desk, housekeeping, and concierge services. A typical Singapore hotel may have 200–500 rooms, each with an ageing phone model that lacks modern features such as programmable speed-dial, voicemail integration, or energy-saving modes. Standardisation reduces training costs, simplifies spare parts inventory, and ensures a consistent guest experience. As of 2026, many hotels are also moving to SIP-based telephony, making it essential to choose phones that support both analogue and digital protocols.
Before ordering any hardware, conduct a thorough site audit. This should include:
For a 300-room property, expect this phase to take 2–3 weeks. Involve the front office manager and chief engineer to capture operational pain points. For example, if guests frequently complain about confusing voicemail prompts, that becomes a requirement for the new call flow design.

Cetis offers a range of hotel telephones from basic analogue sets to advanced SIP models with colour displays. When selecting models, consider:
Prestige Solutions can provide a compatibility matrix and sample units for testing. As of 2026, most new Cetis models support both analogue and SIP modes, giving flexibility for future upgrades.
A phased deployment is recommended to avoid guest disruption. For a 300-room hotel, a typical rollout schedule might be:
| Phase | Rooms | Duration | Key activities |
|---|---|---|---|
| 1. Pilot | 10–20 rooms (one floor) | 1 week | Install, test call flows, train front desk, gather feedback |
| 2. Floors 2–10 | 100 rooms | 2 weeks | Install during low occupancy (mid-week), update room directories |
| 3. Floors 11–20 | 100 rooms | 2 weeks | Same approach, parallel testing with housekeeping |
| 4. Remaining floors | 80 rooms | 1.5 weeks | Final installations, system-wide cutover of call flows |

Post-deployment support is critical for IT managers. Prestige Solutions offers a standard support package that includes:
For ongoing maintenance, consider a service contract that covers annual call flow review and spare parts replenishment. As of 2026, many hotels opt for a 3-year support agreement to lock in service levels and budget predictability.

A phased deployment over 6–8 weeks is common, starting with a pilot floor and expanding to full rollout. The timeline depends on room occupancy, existing cabling, and the complexity of call flow changes.
Most Cetis models support both analogue and SIP protocols, making them compatible with popular PBX systems like Asterisk, Cisco, and Avaya. Prestige Solutions can verify compatibility during the site audit.
Prestige Solutions offers hardware warranty, firmware updates, technical hotline, and on-site support within Singapore. Service contracts can be tailored to your needs.
Yes, standardisation does not mean every room must have the same model. You can choose basic phones for standard rooms and feature-rich models for suites, as long as call flows and programming are consistent.
As a 2026 planning estimate, hardware costs range from SGD 80 to SGD 250 per room, plus installation and infrastructure. Contact Prestige Solutions for a precise quote.
