Hotel PMS Integration: What Your Phone System Should Sync

A hotel PMS integration connects your property management system to the other systems guests touch. For the phone system, it means check-ins, check-outs, room moves and guest names flow from the PMS to the phones automatically, and things like room status can flow back. When it works, the front desk never retypes a room change into the phone system, and a checked-out room never keeps an open line or a waiting voicemail.

Why the phone system needs to talk to the PMS

The PMS knows who is in which room. The phone system knows who is calling from where. Without a link between them, staff keep the two in step by hand: opening and closing room lines, updating names on the console, clearing voicemail and wake-up calls at check-out. That's slow at a busy desk, and every missed step shows up as a guest problem, like a new arrival who hears the last guest's voicemail.

What a PMS-phone integration typically syncs

The exact list depends on the PMS and the phone system, but these are the events most hotels expect:

• Check-in. Opens the room's phone for the stay and sends the guest's name, so the operator sees who is calling.
• Check-out. Resets the room: clears voicemail, the message-waiting light and any wake-up calls.
• Room move. Moves the guest's details, messages and settings to the new room.
• Guest name and details changes. Keeps the console and caller display current.
• Do not disturb and message waiting. Kept consistent between the room phone and the front desk view.
• Wake-up calls. Set from the desk or by the guest, and cleared when the guest leaves.
• Room status. Housekeeping can mark a room clean, dirty or ready, and the status can flow back to the PMS.

Phone-to-PMS events to ask about

Some integrations also send information back from the phone system to the PMS. Ask whether these apply to your property and your vendors:

• Housekeeping status from the room phone, where staff dial a code to update a room's status;
• call charges posted to the guest folio, if you still bill for outside calls;
• minibar or other postings entered from the room phone.

How the connection is usually made

Direct interface to the PMS

Many PMS vendors publish an interface that phone systems can connect to. Oracle's FIAS interface for OPERA is a well-known example. The phone system vendor builds to that interface, and the PMS vendor or your IT team turns the interface on for your property.

Through middleware

Some properties use an interface or middleware product that sits between the PMS and several other systems. That can make it easier to swap one system later, but it adds another vendor, license and point of failure to manage.

Through an API

Cloud PMS platforms increasingly offer open APIs and app marketplaces. That usually makes setup faster and cheaper, and it's worth asking every vendor which route they'll use for your PMS before you compare quotes.

Questions to ask before you sign

• Is my PMS supported today? Ask for the exact PMS, version and hosting model (on-premise or cloud), not just the brand.
• Which events are included? Get the list in writing: check-in, check-out, room move, name change, DND, message waiting, wake-up and room status.
• Who turns it on? Find out whether the PMS vendor charges an interface license or setup fee, and who schedules the work.
• What happens if the link drops? Check that phones keep working and that the systems catch up once the link is back.
• How is it tested? Agree a test plan: check a test guest in, move rooms, leave a voicemail, set a wake-up call and check out, then confirm each step.
