Glossary: AI Telephony Terms

Voicebot, IVR, call forwarding & co. – here we explain the key technical terms around the AI phone assistant briefly and clearly.

AI phone assistant

An AI phone assistant is an AI-powered phone service that answers incoming calls automatically, understands the request and replies in natural language. It captures appointments, reservations or service enquiries and passes the important parts on to the team in a structured way.

Voicebot

A voicebot is an AI system that understands and answers spoken language on the phone. It takes calls, recognises the request and responds in natural language – without a human having to step in.

Phone bot

A phone bot is a software-based assistant that answers and handles telephone calls automatically. Modern phone bots understand freely spoken language, recognise the request and respond in natural language – instead of just playing a key-press menu.

AI telephony

AI telephony refers to the use of artificial intelligence for phone calls – from answering automatically to understanding the request and replying in natural language. It replaces rigid voice menus with flexible, conversation-like dialogue.

Conversational AI

Conversational AI is an umbrella term for AI technologies that hold natural conversations with people – by text (chatbots) or voice (voicebots). It combines speech recognition, language understanding and speech output to handle requests without human intervention.

Voice assistant

A voice assistant is a program that recognises spoken language and responds to it. In a business phone context, a voice assistant takes calls, answers questions and records requests – as the telephone version of well-known voice assistants.

IVR (Interactive Voice Response)

IVR (Interactive Voice Response) is an automated phone system that guides callers through a menu – classically by key press ("Press 1"). It routes calls or gives predefined information without an employee picking up.

Automated call answering

Automated call answering means incoming calls are taken by a system instead of an employee. Modern AI solutions understand the request and respond appropriately, rather than just playing a recorded message.

Call forwarding (Rufumleitung)

Call forwarding ensures incoming calls are automatically redirected to another destination – such as a mobile phone, a colleague or a phone service. It kicks in, for example, when the line is busy, the call isn't answered or outside business hours.

Call transfer (Anrufweiterleitung)

Call transfer refers to passing a call to another person, department or number. It can happen before answering (like call forwarding) or during the conversation, for example to connect the caller to the right contact.

Virtual phone system

A virtual phone system (cloud PBX) manages incoming and outgoing calls over the internet rather than via an on-site phone system. Functions like greeting, routing and reporting run in the cloud and can be used location-independently.

SIP trunk

A SIP trunk is a virtual phone line that connects a phone system to the public telephone network via the internet (VoIP). Instead of physical ISDN lines, calls run over the SIP protocol as data packets.

EU AI Act

The EU AI Act is the European Union's regulation for artificial intelligence. It sorts AI applications into risk classes and mandates transparency obligations – for example that people must be able to tell when they're talking to an AI. Empfango meets this obligation through fixed announcements about AI use and recording.

Site manager (Objektleiter)

A site manager (German: Objektleiter) runs one or more sites for a cleaning or facility services company: they schedule shifts, lead the cleaning team, check quality and are the client's point of contact. A large share of that work happens on the phone – sick calls, complaints and queries.

Dispatcher (Disponent, security services)

A dispatcher (German: Disponent, often also Einsatzleiter) plans the shifts of security staff, staffs the sites, organises cover when someone is absent and is the point of contact for employees and clients. Because shifts run around the clock, on-call duty is part of the job.

Control room / alarm receiving centre (NSL)

An emergency and service control room (German: Notruf- und Serviceleitstelle, NSL) receives alarm and fault signals from connected sites, assesses them and alerts response teams, police or fire brigade. Approved NSLs operate under the VdS 3138 guideline and run an alarm receiving centre to DIN EN 50518. They also take service calls – and that is where routine load builds up.

Operator obligations (Betreiberpflichten)

Operator obligations (German: Betreiberpflichten or Betreiberverantwortung) are the duties of a property's owner or operator to run buildings and technical installations safely, to fulfil duties of care towards the public and to document inspections. Many of these duties are transferred to building service providers – who must then fulfil them verifiably.

Guard logbook (Wachbuch)

The guard logbook, also called Dienstbuch or Wachprotokoll, documents for each site and shift in a security company who was on duty when, which patrols took place and which incidents or irregularities occurred. It is the proof of service towards the client and is increasingly kept digitally.

On-call duty (Rufbereitschaft)

On-call duty (German: Rufbereitschaft) is a form of standby in which employees choose where they stay but must remain reachable and start work when called. Only the time of the actual call-out counts as working time. In building services it carries the night line: absences, faults, alarms.
