Forty per cent of calls to your hotel phone system go unanswered. That figure comes directly from Canary Technologies, whose VP of Product Aman Shahi shared it with Hotel Dive in February 2025 after running an industry-wide analysis. Not 40% of after-hours calls. All calls. And almost none of those guests leave a voicemail; industry research shows that 80 to 85% of callers who reach no one simply move on and never try again.
That’s the problem ääni is built to solve. Understanding why it works, though, requires a look under the bonnet: how the call is received, how the system understands what a guest needs and how it connects to your existing property management and booking infrastructure in real time. If you’ve read our piece on what your AI concierge and your PMS should store, this article picks up where that one leaves off: the mechanics of the call itself.
The Five Moments Where a Guest Phone Experience Goes Wrong
Before getting into the technical flow, it helps to understand the five failure points ääni is specifically designed to intercept.
The first is the missed call. Your front desk team is managing a check-in queue, a billing query and a delivery from a supplier, all at 3pm on a Saturday. The phone rings, nobody answers and a potential booking walks to the OTA instead.
The second is hold music. The call does get answered, but the guest waits three or four minutes while your team finishes another task. By the time someone picks up, the mood has already shifted.
The third is the language barrier. An international guest calls in French or Polish or Arabic, and your team does their best. Confidence drops on both sides of the line, and so does the quality of the booking.
The fourth is the unanswered voicemail. The guest leaves a message. It sits in a queue for two hours. When someone calls back, the guest is unavailable and the cycle repeats.
The fifth is the abandoned booking. After two or three of the above, the guest closes the loop themselves: they go somewhere else.
ääni intercepts all five. Here’s how.
What Happens in the Seconds After a Guest Calls
The technical journey of a call through ääni moves through several distinct stages, each happening in real time, without human intervention and without any drop in quality at 2am versus 2pm.
Call received and routed When a guest dials your hotel’s number, the call reaches ääni immediately if your lines are busy or no one is available. You can also configure ääni as the primary handler for all incoming calls. From the guest’s perspective, there’s no delay and no recorded message asking them to press 1 for reservations.
Language detection ääni identifies the caller’s language from the first few words of the conversation. With over 100 languages and regional accents supported natively (including Arabic, Polish, French, Mandarin and regional British dialects), the system adapts voice, tone and vocabulary to match the caller. This is a multilingual-first architecture, not a translation layer bolted onto an English-language system.
Intent identification ääni doesn’t wait for callers to use specific keywords or follow a menu structure. It understands context and intent from natural speech. A caller asking about a long weekend in April and whether there’s a sea-view room available is understood as a room enquiry with specific preferences. A caller mentioning they booked last week and need to change their check-in to Thursday is understood as a modification request. The system distinguishes between informational enquiries, booking requests, modification requests, complaints and escalation signals.
CRM and PMS lookup For returning guests or active bookings, ääni connects to your CRM and property management system in real time. If the caller has an existing reservation, the system pulls the relevant details (their name, booking reference, room type and any prior preferences stored in the guest profile) and uses that context to personalise the conversation. This is where the integration with Mews PMS becomes particularly powerful: ääni can check live room availability, access rate plans and confirm bookings directly, without any human relay.
Response and action Based on the intent identified and the data retrieved, ääni either answers the enquiry, completes the action (confirming a booking, adjusting a date, answering a question about your facilities) or flags the call for escalation. Confirmations are sent to the guest by their preferred method: text, email or both.
How ääni Connects to Your Hotel Phone System
One of the most common concerns hotels raise when evaluating AI phone systems is the assumption that implementation means replacing existing technology from scratch. ääni is built on the opposite principle. It works with what you already have.
Coir Consulting connects ääni to your property management system, CRM and booking engine through a managed setup process. If you’re running Mews (ääni’s key PMS partner and Best PMS for 2024 and 2025 according to Hotel Tech Report), the integration is deep and direct. ääni can query live room inventory, apply the correct rate plans and write confirmed bookings back to Mews without any manual step in between. For hotels on other PMS platforms, Coir’s team configures the connection to your specific system. For a broader look at how hotel tech integration creates one operating rhythm across your stack, that article covers the wider principle well.
Here’s a practical breakdown of what ääni handles autonomously versus what it escalates to your team:
- Room availability enquiries: handled autonomously via live PMS lookup
- Direct booking confirmation: handled autonomously and written back to your PMS
- Standard booking modifications (date changes, room-type adjustments): handled autonomously
- Facility and amenity questions: handled autonomously based on your property profile
- Check-in, check-out and policy FAQs: handled autonomously
- Complaints, distress calls or sensitive situations: escalated immediately to a human team member, with a full real-time transcript delivered to your staff
- Unusual or high-value requests: flagged for human follow-up with a call summary, so your team has full context before they respond
This balance matters. Cornell Hospitality Research has documented guest satisfaction score increases of up to 25% at properties using AI concierge systems. The aim of ääni is to give your front-of-house team their time back for interactions that genuinely benefit from a human touch, while ensuring every caller gets a fast, accurate, helpful response.
Security, GDPR and What Happens to Guest Data
Any AI phone system handling guest conversations is processing personal data, so this deserves a direct answer. ääni operates under UK GDPR, and Coir Consulting builds compliance into the product architecture from the start.
Guest data from calls (voice audio, transcripts and any booking details captured) is processed on the basis of legitimate interest or explicit consent, depending on the type of processing and the channel. Retention windows are set in line with your legal obligations and are documented. Deletion is triggered and logged. If a guest asks for their data to be erased, that request can be processed across all connected systems.
The ICO publishes detailed guidance on how UK GDPR applies to AI systems, including automated decision-making, which is directly relevant to any AI that routes or acts on guest requests. ääni’s anti-hallucination guardrails also play a practical role: the system responds only using verified information from your property profile and your connected PMS and CRM data, which reduces both inaccurate responses and the regulatory exposure that comes with them.

The Honest Case for 24/7 Cover
A well-configured ääni setup answers every call your hotel receives, in every language your guests speak, at any hour of the day or night, while staying connected to your live booking data. The hospitality sector could save £1.6 billion annually through automation of routine guest-facing activities. At an individual property level, capturing the revenue currently disappearing into unanswered calls and abandoned voicemails is usually the clearest and most immediate return on investment.
ääni isn’t trying to replicate the warmth of a great concierge interaction by machine. It’s trying to make sure every guest who picks up the phone gets a response that’s fast, accurate and appropriate, and that calls requiring real human attention are passed on with enough context for your team to handle them well. That’s a more useful framing than most technology pitches offer, and a better foundation for deciding whether this is the right fit for your property.
Frequently Asked Questions
What CRM and PMS systems does ääni integrate with?
ääni integrates with all major CRM platforms and has a direct partner integration with Mews PMS, one of the most widely used property management systems in the UK and Europe. For hotels running other PMS platforms, Coir Consulting’s implementation team configures the integration to your specific system as part of the managed setup process. In every case, the goal is the same: ääni queries live booking data and writes confirmed reservations back to your existing system without any manual step.
How does ääni handle calls in multiple languages?
ääni supports over 100 languages and regional accents natively. Language detection happens automatically from the first few words of the conversation, and the system adapts its voice, tone and vocabulary to match the caller. It’s a multilingual-first architecture, not an English system with a translation layer added. A guest calling in Arabic gets the same quality of interaction as one calling in English.
What happens if ääni can’t answer a guest’s question?
ääni is configured with anti-hallucination guardrails, meaning it responds only using verified information from your property profile and the data available in your connected CRM and PMS. If a call falls outside the scope of what the system can handle accurately, it escalates immediately to a member of your team with a full real-time transcript of the call. Your staff arrive at the conversation with context, not a blank page.
Is ääni compliant with UK GDPR?
Yes. ääni processes guest data in line with UK GDPR requirements, with retention windows documented and deletion logged and provable. Coir Consulting builds compliance into the product at configuration stage, including consent mapping by channel, DPIA support and processor contract due diligence.
