THE HIDDEN LEAK
Callers on your property line are usually high-intent, closer to booking than website visitors. Yet hotels worldwide still miss a large share of inbound calls during peak hours, nights, and weekends. That demand rarely waits: guests book elsewhere, often through an OTA with commission attached.
D3x Voice answers every inbound call, resolves intent, captures bookings, or hands off to your team with full context.
20–30%
of inbound reservation calls go unanswered in peak windows, widely cited industry estimates for independent and mid-scale hotels
$180K+
estimated annual direct revenue lost per property when missed calls reroute to OTAs, typical analyses for 50–80 room hotels
$1,570
average voice-channel booking value in North America hospitality benchmarks, each unanswered ring can cost far more than one room night
Industry context: Revinate 2024 Hospitality Voice Benchmark (NA); published analyses of missed hotel reservation calls (2024–2025). Figures vary by property size, season, and staffing.
Industry-leading
Inbound on your property lines and in-room phones, connected to your stack via API to execute in your PMS and ops tools during the call, not scripted IVR. Detects the caller's language and switches mid-call when needed. Every caller is authenticated and matched to their reservation before the agent resolves or escalates. Warm handoff with full context when a person is required.

CONVERSATION QUALITY
Guests don't remember your tech stack. They remember whether someone listened, spoke their language, and felt like the hotel they booked, not a call-centre script.
Your operators choose accent, pace, and personality per property, from a precise city-hotel reception to a warm resort concierge. Hundreds of voices and speaking styles, each tuned to the brand it represents.
Good afternoon, Riverside Hotel. I can see your arrival today, are you calling about check-in or your room preference?
A guest calls in Spanish, switches to English mid-conversation, or rings back in another language. D3x follows naturally on property lines and in-room phones, across 100+ languages.
No press-1-for-reservations. Open dialogue from the first word: verify the stay, handle the request, or hand off to your team with full context when a person is needed.
After 20,000 guest surveys, D3x AI scores 4.58 against a 4.62 human benchmark, not because it mimics scripts, but because it resolves like someone who actually works there.
100+ languages · hundreds of voices and accents · configured per property · measured in production
MID-CALL LANGUAGE
Detect the caller's language from the first words and respond naturally. If they switch mid-call: German to English, French to Spanish, the agent follows without starting over or transferring.

BRAND VOICE
The person who answers the phone is the first impression of your property. D3x lets you choose exactly how that sounds, in every language your guests speak, on every line you run.
VOICE CLONING
Record your best front-desk host or your brand ambassador once, and every property in the group answers with that same voice, at any hour, in any language.
Brand voice · Riverside Group
Cloned from your host · used on all lines
AUTOMATIC LANGUAGE SWITCH
No menus, no 'press 2 for English'. The agent hears the switch mid-sentence and keeps the same conversation going.

Of course, we can extend checkout to 2pm tomorrow.
Same call · same context · no restart
NOISE CANCELLATION
Traffic, rolling suitcases, a crowded bar behind the caller. The agent separates the voice from the room and answers what was actually said.
What the line carries
What the agent hears
Fewer repeats · fewer misheard names
PERSONA & TONE
Tone is set per property, not per group, so a five-star concierge and a budget city hotel never sound like the same script.
Configured per property, changed in minutes
Guests remember how they were greeted long after they forget the room rate. This is the part of your brand that answers at 3am.
LIVE VOICE SKILLS
D3x Voice uses your existing D3x knowledge base and hospitality skills, so the agent starts with the facts, policies, and routing rules your team already trusts.
Already trained
Because Voice uses the same D3x knowledge base as messaging and email, your property facts, policies, escalation rules, and brand tone carry over automatically.
Human handoff
When a guest asks for a person, or your policy requires one, the AI transfers the call to any phone number or queue you define.
Front office · reservations · lost and found · any team number
Booking intent
The agent confirms dates, guest count, preferences, live rates, and availability, then sends a WhatsApp or SMS deep-booking link so the guest can complete immediately.
Intent captured · PMS checked · booking link sent
Reservation check
Guests can verify their stay with surname and reservation number, or by caller ID where available, and get a clear confirmation on the call.
Surname · reservation number · caller ID match
Group meetings
When callers ask about hosting a group meeting or event, the agent captures the details, creates a ticket for your team, and confirms someone will reach out within 24 hours.
Ticket created · team follow-up within 24 hours
Parking
When callers ask about parking, availability, rates, or how to book, the agent answers from your policy on the call, then sends a WhatsApp message with details or a link to reserve or pay.
Policy answered · WhatsApp link sent during the call
THE FULL GUEST JOURNEY
The same Skills Engine on voice, not phone trees. Pre-arrival confirmation and upsell, in-stay housekeeping and maintenance, post-stay invoices and recovery. Every phase logged and connected to your PMS and ops stack.
Guests call before check-in with arrival questions, booking intent, or missing details. D3x confirms reservations, sends check-in and booking links, answers policy questions, and surfaces upsells while intent is highest.
Booking confirmation
Returns check-in time, room category, and add-ons from your PMS, reassurance before they travel.
Online check-in link
Magic link with secure token, guests complete pre-arrival check-in without a new account.
Live rates & upsell
Real-time availability, parking, breakfast, and early check-in offered in the call.
OTA & channel matching
Reservation IDs matched across Booking.com, channel managers, and PMS, including channel quirks generic AI misses.
Group & event intent
Corporate stays and meetings routed to sales with structured details collected during the call.
Payment & check-in workflows
Configured operational logic, not a prompt, with brand voice and per-property rules.
LIVE CONNECTIONS
D3x connects to your PMS, housekeeping tools, CRM, and telephony in real time. When a guest calls, we look up their booking and take action before we speak, so every reply is accurate, personal, and up to date.
On the main number, department line, or room phone, the channel they already use.
Name, booking reference, or phone number matched to the right reservation in your PMS.
Room status, add-ons, housekeeping tickets, CRM notes, pulled in seconds, not copied from a PDF.
A clear reply on the same channel, or a handover to your team with full context if a human should step in.
What the caller asks
Hi, we're in room 412. Is late checkout possible tomorrow? Our train isn't until 3pm.

THE DIFFERENCE
Reads a static script. Can't see today's availability, this guest's booking, or whether housekeeping already visited the room.
THE DIFFERENCE

TELEPHONY & ROUTING
D3x answers on your own numbers and connects to your existing PBX over SIP. Transfers travel down the trunk instead of bridging a second call, so handoffs are faster, the audio stays clean, and the guest never sits in dead air.
NO MORE PHONE TREES
D3x Voice becomes the intelligent call layer: it answers, understands intent, verifies the guest, checks live systems, and either resolves the request or transfers to the right person.
Legacy PBX / IVR
D3x Voice
TRANSFER MODES
The agent briefs your team before connecting: who is calling, their reservation, and what they have already asked. Staff pick up mid-conversation, not from zero.
For straightforward routing the caller is passed directly to the right number or queue, with the transcript still attached to the thread.
Transfers run natively over your SIP trunk rather than a bridged second leg, cutting latency and keeping call quality at carrier level.
Routing
Reception, reservations, housekeeping, the duty manager, a regional sales desk, or an external number. Rules are set per property and per scenario, and changing them does not mean rebuilding a phone tree.
Infrastructure
Keep your current telephony provider, numbers, and extensions. D3x plugs into the SIP trunk you already have and becomes the intelligent layer in front of it, so nothing gets ripped out to go live.
Capacity
Capacity is not limited by how many people are at the desk. The checkout rush, a group arrival, and a 2am call can all be answered simultaneously, on the first ring.
In-room
Guest-room phones reach the same agent, with room number and reservation context already attached, so housekeeping, maintenance, and front desk requests turn into tasks without anyone walking to the desk.
Voice library
Choose the voice, accent, and speaking style per property, from precise city-hotel reception to a warm resort concierge, with pronunciation rules for your brand, place, and dish names.
Audio quality
Background noise from lobbies, airports, taxis, and busy streets is filtered out before the agent listens, and state-of-the-art language handling follows the guest when they change language mid-call.
WHAT THE AGENT DOES ON THE CALL
Property numbers stay the same · runs alongside your PBX during rollout · SIP trunk transfer for low-latency handoff · cold and warm transfer supported per scenario
BUILT-IN FUNCTIONS & INTEGRATIONS
Natural speech is only one layer. D3x Voice combines LLM reasoning, telephony, PMS data, routing rules, and audit trails so calls can be resolved, transferred, or turned into action.
Understands intent in open conversation, asks clarifying questions, and stays inside your approved hospitality workflows.
Reads real-time PMS data before answering availability, rate, upsell, and stay-detail questions.
Matches callers through phone number, surname, reservation reference, or guest data depending on your setup.
Voice infrastructure can run close to your region for fast call response and GDPR-aligned data handling.
When staff takes over, the AI mutes itself, listens, transcribes, and turns knowledge gaps into improvements.
Personalized greetings, brand-specific personality, and pronunciation rules for names, places, and hotel brands.
PLATFORM CONTROLS
Beyond answers and integrations: measure satisfaction, set when automation runs, route to humans with full context, and log every call for review.
Turn on customer satisfaction scoring per thread to compare AI and human performance, spot what works, what needs coaching, and where to escalate.
Set opening hours for each day and time slot. Automation when you want it; different rules after hours, handover, auto-reply, or queue for morning.
Define what happens when a message matches a rule, not one-size-fits-all.
Any guest request can become a structured ticket, summarised with room and reservation context, and forwarded to your operations team by email, WhatsApp, or your helpdesk.
Configurable recording, retention, and access policies, aligned with how your legal and operations teams handle guest calls.
When a human is needed, the agent transfers with spoken summary plus reservation context, your staff never asks the guest to repeat themselves.
CALL TO MESSAGE
When a guest asks for something that is easier as a link, confirmation, photo, policy, or follow-up, D3x can send WhatsApp or SMS during the call or right after hang-up. The thread keeps the call summary, reservation context, and next action, so the guest never starts over.
01
They ask on the property line, room phone, or main number, no app download.
02
The voice agent confirms consent and chooses WhatsApp or SMS based on the guest and market.
03
Booking links, policies, invoices, maps, photos, and ticket updates land while the call is still fresh.
04
Guest replies later in the same conversation; operators see the call transcript and full context.

Transcription
Calls are transcribed in full and searchable, so quality reviews, coaching, and knowledge gaps run on what was actually said rather than on a sample someone had time to listen to.
Accountability
Reports show when the guest called, which team the call was routed to, who answered, who missed it, and how long the caller waited, per property and per shift.
One inbox
Voice is not a separate tool. Every call appears in the same inbox as WhatsApp, SMS, email, and web chat for that guest, so operators read one timeline instead of stitching three together.
Fallback
If the caller cannot reach anyone, or human connect is switched off, the agent captures what they wanted, their callback number, and the reservation context, then raises a ticket for the right team instead of losing the call.
Lead capture
Group enquiries, event requests, corporate stays, and any other high-value intent are collected as structured leads with the details your sales team needs, and routed to them the same minute.
Revenue
End-to-end attribution follows a call from intent to booking link to confirmed reservation, so you can see which calls, teams, and hours actually produce revenue, not just how many rings were answered.
