Hotel phone system in Morocco: rooms, PMS, wake-up calls and call billing

The short answer: in a hotel, the phone system is more than a front-desk tool. It must talk to the property management system (PMS) to open and close room calling rights, display the guest’s name, schedule wake-up calls, track housekeeping and post calls to the bill. 3CX, Yeastar and Grandstream can all do this, usually through the FIAS protocol, but under different conditions: model, edition, paid module, accepted protocol. This guide relies only on what the vendors document.

For the general choice between these three solutions, see our guide to business IP phone systems in Morocco. Here we focus on what is specific to hotels.

What a hotel phone system must do

Function	What it brings
Check-in and check-out	Room calling rights opened at check-in, closed at check-out, call log cleared
Guest name	Reception sees who is calling; the phone can greet the guest by name
Wake-up calls	Scheduled by reception or by the guest from the room
Room status	Housekeeping reports “clean”, “dirty”, “inspected” from the room phone
Do not disturb	Enabled from the room or by reception
Call billing	Outbound calls rated and posted to the guest bill
Minibar	Consumption entered from the room phone, depending on the system
Service keys	Reception, room service, concierge, with one press

A security point from the outset: by default, a vacant room should only call reception and emergency numbers. An occupied room gets outside calls only if the hotel decides so. This is the first protection against toll fraud.

The PMS and the FIAS protocol

The PMS (Property Management System) is the software that manages bookings, rooms and billing. To exchange data with the phone system, many PMS products use FIAS (Fidelio Interface Application Specification), Oracle Hospitality’s interface protocol, which comes from Micros Fidelio. Others use the Mitel protocol or go through middleware.

So the question to ask your PMS vendor is simple: which telephony interface do you offer, using which protocol, and does it need an interface licence on your side? The answer shapes the choice of phone system. Ask also whether the interface runs on the PMS server or on a separate machine, and who supports it when the link drops: the PMS vendor, the phone system integrator, or both.

3CX: the hotel module and its two protocols

According to 3CX documentation, the hotel module integrates with PMS products in two ways:

• The Fidelio protocol (FIAS), for Micros Fidelio and Protel. 3CX states that FIAS is supported by Fidelio Suite 6, 7 and 8 and OPERA, but not by Fidelio Xpress. In this mode, 3CX sends the PMS the calls made from the room (time, destination and cost based on the rates configured in 3CX); the PMS can use that cost or recalculate it.
• The Mitel SX2000 protocol, for Mitel-compatible software. 3CX notes that this protocol has no call billing interface.

In both cases, the PMS must be reachable on the phone system’s local network, and the integration is set in the admin console, under hotel services. Without a PMS, reception can assign a room to a guest and clear it from the 3CX Web Client; the documentation notes that no billing receipt is then generated at check-out.

3CX suits a hotel that uses a FIAS PMS and also wants 3CX’s strengths: mobile apps for staff, a contact centre for reservations, WhatsApp and web chat. As a 3CX partner in Morocco, we check compatibility with your PMS before any proposal.

Yeastar P-Series: built-in hotel module or FIAS integration

Yeastar offers two approaches, documented in its help centre:

• The hotel management module, built into the phone system as an add-on subscription with a trial period. Reception uses Linkus (desktop or web app) to handle check-ins, check-outs and room moves, wake-up calls, room status and do not disturb. Guests can set their wake-up call from the room phone. Outbound calls are rated with call rate rules and posted to the bill. By default, rooms can only call service and emergency numbers.
• PMS integration over FIAS, tested by Yeastar with Oracle Hospitality OPERA and, according to Yeastar, applicable to FIAS-compatible PMS products. Depending on what the PMS supports: guest name assigned to the extension at check-in, wake-up calls scheduled from the PMS, call and minibar charges posted to the bill, do-not-disturb sync. On the Appliance edition, Yeastar states that this integration is limited to the P550, P560 and P570; the Software edition requires the PMS integration add-on.

For PMS products that do not support FIAS, Yeastar points to its open API for custom integration. Model choice is covered in which Yeastar P-Series to choose.

Grandstream UCM: built-in PMS, FIAS and middleware

Grandstream is the most hotel-oriented vendor of the three:

• The local PMS built into the UCM6300 manages rooms, check-ins, wake-up calls (including recurring ones), the minibar and housekeeping, with no external hotel software.
• Oracle OPERA integration over FIAS, through Oracle’s interface dedicated to Grandstream UCMs. Grandstream’s documentation lists check-in and check-out, room moves, wake-up calls, housekeeping status, do not disturb, per-room calling rights, minibar and external call billing, plus the guest name shown on auto-provisioned phones. It covers the UCM6300 and UCM6300 Audio series and CloudUCM, with a minimum firmware version.
• Other integrations: Grandstream cites HMobile, HSC, Mitel and IDS, plus an open PMS API for integrators.

Grandstream also states that the room’s call history can be cleared automatically at check-out, a useful privacy feature. UCM capacities are covered in which Grandstream UCM to choose.

Comparing the three approaches

Criterion	3CX	Yeastar P-Series	Grandstream UCM
Hotel functions without a PMS	Check-in and check-out from the Web Client	Full hotel module (subscription)	Built-in local PMS
FIAS integration	Yes (Fidelio, Protel, OPERA)	Yes (OPERA, Fidelio), P550 to P570 or Software edition	Yes (Oracle OPERA)
Other protocols	Mitel SX2000	Open API	HMobile, HSC, Mitel, IDS, API
Call billing	Via FIAS	Hotel module or FIAS	Via OPERA or direct billing
Room phones	Compatible SIP phones	Compatible SIP phones	Dedicated GHP series, auto-provisioned

Our honest view: Grandstream covers the most hotel functions natively, with dedicated room phones. Yeastar offers a complete hotel module and simple day-to-day management. 3CX is mostly justified when the hotel also wants a real contact centre for reservations. In every case, compatibility with your PMS is confirmed before purchase.

Phones: rooms, reception, mobile staff

• Rooms: discreet phones with service keys. Grandstream’s GHP series comes in WiFi versions, which avoids pulling a cable into a renovated room.
• Reception: phones with many busy-lamp keys, a headset, and a view of room status.
• Mobile staff (housekeeping, room service, maintenance, security): DECT handsets, or WiFi phones such as Grandstream’s WP series, if the WiFi is designed for voice.
• Common areas: courtesy phones in the lobby, limited to internal calls.

A hotel network: separate, prioritise, cover

Hotel telephony often shares the building with heavily used guest WiFi. Put voice in a dedicated VLAN with priority, and fully isolate the guest network. For WiFi phones, coverage must be designed for voice in corridors, kitchens and basements; see high-density enterprise WiFi. Plan a UPS for the phone system and switches, and a backup for the internet link or SIP trunk.

Guest data and recording

Guest names, numbers called from rooms, wake-up times: these are personal data covered by law 09-08. Restrict access, set retention periods and delete stay-related data according to your rules. Never record room calls; if the reservations desk records its calls, the conditions are covered in call recording for businesses.

Mistakes we fix in hotels

1. Vacant rooms open to international calls, an ideal fraud target.
2. A PMS bought without a telephony interface, discovered at integration time.
3. Wake-up calls scheduled by hand on paper, for lack of integration.
4. Guest WiFi and voice on the same network, hence poor audio in the evening.
5. Call logs never cleared between guests.

How a successful PMS integration unfolds

1. Inventory: number of rooms and phones, PMS used, its version, and the telephony interface it offers.
2. Validation with the PMS vendor: protocol, interface licence, network settings, and who configures what on each side.
3. Numbering plan: extension number equal to room number, short service numbers, calling rights per room category.
4. Configuration and tests: check-in, room move, check-out, wake-up, do not disturb, billed call, minibar where relevant. Each function is tested on a pilot room before rollout.
5. Training for reception, housekeeping and maintenance, each on what they actually use.
6. Follow-up in the first weeks: a PMS link that drops without an alert means missed wake-up calls and unbilled calls. It must be monitored like everything else.

Checklist before choosing

• PMS identified, with its telephony interface and licence.
• Expected functions listed: wake-up, billing, housekeeping, minibar, guest name.
• Calling rights defined for vacant and occupied rooms.
• Phones chosen: rooms, reception, mobile staff, common areas.
• Voice network separated from guest WiFi, DECT or WiFi coverage checked.
• Retention rules for guest data set.
