Definitions for the Terms That Show Up Across Densy AI
Plain-English definitions for the AI communication vocabulary and the industry acronyms — DMS, TMS, PMS, ATS, BDC, IVR — that show up across Densy AI, our industry pages, and our insights articles.
AI appointment booking
AI appointment booking is software that books appointments directly into a business calendar, PMS, DMS, ATS, or TMS during an inbound call, SMS, or web form conversation — with no human staff involved.
Unlike a chatbot that only collects intent, an AI appointment booking system checks live availability in the target system, confirms the slot with the caller, and writes the booking back — plus sends SMS and email confirmations. Setup typically takes 24–48 hours per business.
AI phone answering service
An AI phone answering service is a subscription platform that answers every inbound business call 24/7 using conversation AI — greeting the caller, qualifying the request, and taking action such as booking an appointment or capturing a lead.
Historically, phone answering services relied on human call centers. Modern AI phone answering services conduct natural two-way conversations, integrate with the business software you already use, and cost a fraction of a human call center for equivalent coverage.
AI receptionist
An AI receptionist is software that answers inbound business calls 24/7, qualifies leads, books appointments, sends SMS follow-ups, and routes complex calls to your team — using natural conversation instead of phone-tree menus.
Unlike chatbots or IVR systems, an AI receptionist holds a real two-way conversation and takes meaningful action during the call. Most service businesses use one to eliminate missed calls, provide after-hours coverage, and let front-desk staff focus on customers already in the office.
ATS (Applicant Tracking System)
An ATS is the system of record for a recruiting team's candidate pipeline — tracking applications, interviews, dispositions, and hires from application to offer.
Major ATS platforms include Greenhouse, Lever, Bullhorn, Workday, iCIMS, JobAdder, Workable, Ashby, and SmartRecruiters. Densy AI writes candidate transcripts, dispositions, and scheduled interviews back to the ATS automatically, so recruiters work from a single source of truth.
BDC (Business Development Center)
A BDC is the internal team at an auto dealership that handles inbound service, sales, and internet leads — typically operating separately from the sales floor and service drive.
BDCs exist to protect the sales team from getting pulled off the floor for every inbound call and to make sure internet leads receive a fast response. Densy AI augments the BDC by handling the first response — answering, qualifying, and scheduling — so BDC reps focus on the leads that are ready to buy.
Customer reactivation
Customer reactivation is the practice of re-engaging dormant customers — usually those who have not purchased, visited, or interacted with the business for a defined period — through personalised outbound outreach.
Densy AI runs reactivation campaigns across SMS, email, and outbound voice. Each message uses the customer's history to feel personal, and when the customer responds, the AI handles the follow-up conversation and books the appointment or captures the intent directly.
DMS (Dealer Management System)
A DMS is the core operational software for an auto dealership — managing service appointments, repair orders, sales deals, parts inventory, and customer records in one system.
Major DMS platforms include CDK Global, Reynolds & Reynolds, Dealertrack, Tekion, Auto/Mate, and DealerSocket DMS. Densy AI reads live availability from the DMS, books service appointments into the schedule, and can pre-stage repair orders with the caller-reported concern.
IVR (Interactive Voice Response)
An IVR is a legacy phone menu system that routes callers based on key presses ("Press 1 for sales, Press 2 for service") — it cannot hold a real conversation or take action on the caller's behalf.
IVRs are what an AI receptionist replaces. A modern AI receptionist conducts a natural two-way conversation, understands intent from what the caller actually says, and takes action — booking the appointment, capturing the lead, or routing the call — instead of just routing based on menu presses.
Missed call recovery
Missed call recovery is the automated process of engaging a caller whose call was not answered — typically by sending an immediate SMS and, if needed, initiating a follow-up conversation to capture the lead or book the appointment.
Missed call recovery is one of the highest-ROI automations for service businesses because the caller has already expressed intent. Densy AI recovers missed calls automatically, so calls that would have rolled to voicemail become booked appointments instead.
Missed call text back
Missed call text back is a specific form of missed call recovery: when the business does not answer, the caller receives an SMS within seconds acknowledging the missed call and continuing the conversation over text.
Missed call text back is one of the fastest-growing service-business automations because SMS response rates are substantially higher than voicemail callback rates, and the caller experiences the response as immediate.
Patient reactivation
Patient reactivation is customer reactivation applied to healthcare and dental practices — re-engaging patients who have not booked an appointment in a defined period, typically 12, 18, or 24 months.
In dental and medical practices, roughly one in three active patients is overdue for a visit at any given time — not because they switched providers, but because no one reached out. Densy AI runs patient reactivation campaigns automatically across SMS, email, and outbound voice.
PMS (Practice Management System)
A PMS is the operational software for a dental or medical practice — managing patient appointments, records, insurance, billing, and clinical notes in one system.
Major dental PMS platforms include Dentrix, Eaglesoft, Open Dental, Curve Dental, and Carestream. Densy AI reads live schedule availability from the PMS, books appointments into the practice's schedule, and can update patient records with call outcomes and reactivation history.
Silver-medalist candidate
A silver-medalist candidate is a past applicant who reached late-stage interviews or received an offer but did not join — a strong candidate who came close but did not close.
Silver-medalists are the highest-ROI segment for candidate reactivation because they are already familiar with the role and the employer. Densy AI segments silver-medalists in the ATS and runs reactivation outreach when new similar roles open — often producing better hires than a fresh sourcing campaign.
Speed to lead
Speed to lead is the elapsed time between an inbound lead's inquiry and the first substantive response from the business — a single metric that predicts conversion better than almost any other.
Industry research has consistently shown that a five-minute delay drops conversion by an order of magnitude, and most businesses respond in hours or days. Densy AI closes the gap by engaging inbound leads within seconds across SMS, email, and voice — before a competitor gets there first.
TMS (Transportation Management System)
A TMS is the operational software used by 3PLs, freight brokers, and logistics operators — managing shipment planning, execution, tracking, carrier selection, and freight billing in one system.
Major TMS platforms include MercuryGate, McLeod, Project44, FourKites, Descartes, Magaya, CargoWise, and MyCarrierTMS. Densy AI is configured per client to work with the TMS — either reading live shipment status during a call or routing the caller to the right CS rep with a TMS deep-link attached.
