Each row opens a page with the definition, why the term matters and what to ask a vendor. ### A - Security & compliance #### [Access control](https://telxpress.com/glossary/access-control/) Access control is the system of electronic locks, readers, credentials and management software that decides who may enter which door and when, and records every entry, replacing keys that cannot be revoked. - AI #### [Agentic AI](https://telxpress.com/glossary/agentic-ai/) Agentic AI describes AI systems that can take actions to complete a goal, such as booking an appointment, updating a CRM record or sending a follow-up, rather than only answering questions. - AI #### [AI governance policy](https://telxpress.com/glossary/ai-governance-policy/) An AI governance policy is the written set of rules a business adopts for how AI tools may be used, what data they may touch, who approves them and how their output is checked. - AI #### [AI readiness](https://telxpress.com/glossary/ai-readiness/) AI readiness is a measure of how prepared a business is to put AI to work, covering its phone and call handling, data and systems, network, meeting rooms, policies and leadership commitment. - Voice #### [AI receptionist](https://telxpress.com/glossary/ai-receptionist/) An AI receptionist is an AI voice agent configured for front-desk work: greeting callers, answering routine questions, routing calls to the right person and scheduling, so staff handle visitors and exceptions. - Voice #### [AI voice agent](https://telxpress.com/glossary/ai-voice-agent/) An AI voice agent is software that answers phone calls in natural conversation, understands what the caller wants, answers questions, books appointments and transfers or takes messages when a person is needed. - AI #### [AI-native business](https://telxpress.com/glossary/ai-native-business/) An AI-native business is a company that designs its everyday operations, from answering calls to following up leads, around AI tools working alongside people, rather than adding AI as an afterthought. - Voice #### [Auto attendant](https://telxpress.com/glossary/auto-attendant/) An auto attendant is the recorded phone menu that greets callers and routes them by keypad or spoken choice (press one for sales), without a live person or a conversation. - Audio visual #### [Auto-framing camera](https://telxpress.com/glossary/auto-framing-camera/) An auto-framing camera is a meeting-room camera that uses AI to detect the people present and zoom, pan and crop, so remote participants see faces clearly instead of a wide shot of an empty table. ### C - Security & compliance #### [Call recording consent](https://telxpress.com/glossary/call-recording-consent/) Call recording consent is the permission the law requires before a phone call is recorded; in California, every party to a confidential call must be told and agree, which is often called two-party consent. - Voice #### [Call routing](https://telxpress.com/glossary/call-routing/) Call routing is the set of rules a phone system or AI agent uses to decide who receives an incoming call, based on the caller, the time, the reason, availability and skills. - Network #### [Cat6 vs Cat6A](https://telxpress.com/glossary/cat6-vs-cat6a/) Cat6 vs Cat6A is the choice between two grades of twisted-pair copper cabling; Category 6A supports higher-speed Ethernet over the full standard distance and resists interference better, at higher cost and a thicker cable. - Phones #### [Cloud phone system](https://telxpress.com/glossary/cloud-phone-system/) A cloud phone system is a business phone service hosted by a provider and delivered over the internet, so phones, apps and features are managed through a web portal rather than hardware in your office. ### D - Connectivity #### [Dedicated internet access](https://telxpress.com/glossary/dedicated-internet-access/) Dedicated internet access (DIA) is a business internet service whose full bandwidth is reserved for one customer, with a service-level agreement for uptime, latency and repair time, unlike shared broadband. - Audio visual #### [Digital signage](https://telxpress.com/glossary/digital-signage/) Digital signage is a network of displays in lobbies, waiting rooms, showrooms and work areas that show scheduled content such as welcomes, menus, promotions, wayfinding and live data, managed centrally from a web console. ### E - Phones #### [E911](https://telxpress.com/glossary/e911/) E911 (enhanced 911) is the emergency-calling capability that sends a caller's phone number and location to dispatchers; for business phone systems, Kari's Law and RAY BAUM's Act set specific federal requirements. ### F - Connectivity #### [Failover](https://telxpress.com/glossary/failover/) Failover is the automatic switch to a backup connection, device or route when the primary one fails, so that phones, payments and cloud applications keep working through an internet or equipment outage. - Security & compliance #### [FERPA](https://telxpress.com/glossary/ferpa/) FERPA (the Family Educational Rights and Privacy Act) is the federal law that protects the privacy of student education records and gives parents and eligible students rights to inspect and correct them. - Network #### [Firewall](https://telxpress.com/glossary/firewall/) A firewall is the security device or service that inspects traffic entering, leaving and crossing your network and allows or blocks it by rule, protecting your systems from the internet and from each other. - Connectivity #### [Fixed wireless](https://telxpress.com/glossary/fixed-wireless/) Fixed wireless is business internet delivered by a radio link between an antenna on your building and a nearby tower or base station, used where fiber is unavailable or as an independent backup connection. - Security & compliance #### [FTC Safeguards Rule](https://telxpress.com/glossary/ftc-safeguards-rule/) The FTC Safeguards Rule requires non-bank financial institutions, including car dealerships that arrange financing, to keep a written information security program with named elements such as risk assessments, access controls, encryption and multi-factor authentication. ### G - Security & compliance #### [GLBA](https://telxpress.com/glossary/glba/) GLBA (the Gramm-Leach-Bliley Act) is the federal law requiring financial institutions to explain how they share customers' nonpublic personal information and to protect that information with a security program. ### H - AI #### [Hallucination](https://telxpress.com/glossary/hallucination/) A hallucination is a confident but false statement produced by an AI model, such as an invented policy, price or appointment slot, and it is the main accuracy risk in any customer-facing AI system. - Security & compliance #### [HIPAA business associate agreement](https://telxpress.com/glossary/hipaa-business-associate-agreement/) A HIPAA business associate agreement (BAA) is the written contract a healthcare provider must have with any vendor that creates, receives, stores or transmits protected health information on its behalf. ### I - Voice #### [IVR (interactive voice response)](https://telxpress.com/glossary/ivr/) An IVR, or interactive voice response system, is an automated phone system that interacts with callers through voice prompts and keypad or spoken input to answer questions, collect information or route the call. ### J - Network #### [Jitter](https://telxpress.com/glossary/jitter/) Jitter is the variation in the time it takes voice or video packets to arrive; when it is high, a call sounds choppy or robotic because the receiving device cannot smooth the uneven stream. ### L - AI #### [Large language model](https://telxpress.com/glossary/large-language-model/) A large language model (LLM) is an AI system trained on vast amounts of text that can follow instructions and generate fluent language; it powers chat assistants and the conversation in AI voice agents. - Network #### [Latency](https://telxpress.com/glossary/latency/) Latency is the time a packet takes to travel from one end of a connection to the other; on a phone or video call, high latency makes people talk over each other and pause awkwardly. - AI #### [Lead qualification](https://telxpress.com/glossary/lead-qualification/) Lead qualification is the process of asking a prospect enough questions to decide whether, how urgently and by whom they should be followed up, a task businesses increasingly give to AI voice agents. ### M - Security & compliance #### [MFA (multi-factor authentication)](https://telxpress.com/glossary/mfa/) Multi-factor authentication (MFA) requires a second proof of identity beyond a password, such as a code from an app or a hardware key, and it defeats most attacks that rely on stolen passwords. ### N - Phones #### [Number porting](https://telxpress.com/glossary/number-porting/) Number porting is the process of moving your existing phone numbers from one carrier or phone provider to another, so a change of phone system never means a change of the numbers your customers know. - Security & compliance #### [NVR (network video recorder)](https://telxpress.com/glossary/nvr/) A network video recorder (NVR) is the appliance or server that receives video from IP security cameras over the network, stores the recordings and lets authorized staff review, search and export footage. ### P - Network #### [Packet loss](https://telxpress.com/glossary/packet-loss/) Packet loss is the share of packets that never reach their destination; on a voice or video call even a small amount causes dropped words, frozen video and a line that seems to cut out. - Phones #### [PBX](https://telxpress.com/glossary/pbx/) A PBX (private branch exchange) is a business phone system that switches calls between internal extensions and the outside world; it can be a box on your premises or a hosted service in the cloud. - Security & compliance #### [PCI DSS](https://telxpress.com/glossary/pci-dss/) PCI DSS (Payment Card Industry Data Security Standard) is the set of security requirements every business that stores, processes or transmits payment card data must meet, including card payments taken over the phone. - Network #### [PoE (Power over Ethernet)](https://telxpress.com/glossary/poe/) Power over Ethernet (PoE) delivers power to devices such as phones, Wi-Fi access points, cameras and room controllers through the same network cable that carries their data, so no outlet is needed at the device. ### Q - Network #### [QoS (quality of service)](https://telxpress.com/glossary/qos/) Quality of service (QoS) is the network configuration that identifies time-sensitive traffic such as voice and video and gives it priority over downloads and backups, so calls stay clear when the network is busy. ### R - AI #### [Retrieval-augmented generation](https://telxpress.com/glossary/retrieval-augmented-generation/) Retrieval-augmented generation (RAG) is a technique in which an AI system first looks up relevant documents or records and then answers from them, so replies are grounded in your information rather than the model's memory. ### S - Connectivity #### [SD-WAN](https://telxpress.com/glossary/sd-wan/) SD-WAN (software-defined wide area network) is a service that combines two or more internet connections at a site, steers each application over the best path and fails over automatically when one connection degrades. - Phones #### [SIP trunk](https://telxpress.com/glossary/sip-trunk/) A SIP trunk is a virtual phone line delivered over the internet that connects your own phone system (an on-site or hosted PBX) to the public telephone network, replacing traditional analog or digital carrier lines. - Voice #### [Speech-to-text](https://telxpress.com/glossary/speech-to-text/) Speech-to-text (STT) is the technology that converts spoken words into written text in real time; it is the first stage of an AI voice agent and the basis of call transcripts, captions and meeting notes. - Network #### [Structured cabling](https://telxpress.com/glossary/structured-cabling/) Structured cabling is the standardized, organized system of copper and fiber cables, patch panels, racks and outlets that connects every phone, computer, access point, camera and room system in a building to the network. ### T - Security & compliance #### [TCPA](https://telxpress.com/glossary/tcpa/) The TCPA (Telephone Consumer Protection Act) is the federal law that restricts automated calls, prerecorded or artificial voice messages and marketing texts to consumers, and generally requires their prior express consent. ### U - Phones #### [UCaaS](https://telxpress.com/glossary/ucaas/) UCaaS (unified communications as a service) is a cloud subscription that combines business phone calling, video meetings, team messaging, voicemail and often contact-center features in one platform managed by the provider. ### V - Audio visual #### [Video conferencing room](https://telxpress.com/glossary/video-conferencing-room/) A video conferencing room is a meeting space with a display, camera, microphones and a room system such as Teams Rooms or Zoom Rooms, so meetings start with one touch and remote participants hear everyone. - Network #### [VLAN](https://telxpress.com/glossary/vlan/) A VLAN (virtual local area network) splits one physical network into separate logical networks, so that phones, computers, guest Wi-Fi, cameras and building systems are kept apart for security and performance without separate cabling. - Phones #### [VoIP](https://telxpress.com/glossary/voip/) VoIP (voice over internet protocol) carries phone calls as data over an internet or private IP network instead of traditional copper phone lines; cloud phone systems, UCaaS and SIP trunks are all built on it. ### W - Voice #### [Warm transfer](https://telxpress.com/glossary/warm-transfer/) A warm transfer hands a caller to a colleague only after the person transferring has spoken to that colleague, passed on the caller's name and reason, and confirmed they are ready to take the call. - Network #### [Wi-Fi 6, 6E and 7](https://telxpress.com/glossary/wi-fi-6-6e-7/) Wi-Fi 6, 6E and 7 are the most recent generations of wireless networking; each handles more devices in a crowded office with less delay, and 6E and 7 add the less congested 6 GHz band. - AI #### [Workflow automation](https://telxpress.com/glossary/workflow-automation/) Workflow automation uses software rules and AI to run repeatable business steps automatically, such as logging a lead or sending a confirmation; CRM automation is the same idea applied inside your customer database. 02 How to use it ## Four ways to *use a definition* Every entry follows the same shape, so a page you have read once is a page you can skim next time. 1. 01 ### Quote the one-liner The first sentence of every entry is the definition. Use it as written in a proposal, a policy or a training deck. 2. 02 ### Read why it matters The body explains what changes for a growing business when the term enters a quote or a contract. 3. 03 ### Bring the questions Each entry ends with what to ask a vendor. Ask them in the meeting and write down the answers. 4. 04 ### Follow the links Related terms and the Telxpress pages where the term shows up in practice, plus the public source text. The definitions come from the work itself: the [AI advisory engagements](https://telxpress.com/ai-advisory/) where these words decide a roadmap, the [Donya voice agent](https://telxpress.com/solutions/ai/voice-agent/) that answers on them, and the [business technology](https://telxpress.com/solutions/business-technology/) we install and support in Orange County. 03 Questions ## Questions about the glossary **Who writes these definitions and how often are they reviewed?** The Telxpress advisory team writes them from the questions owners and IT managers ask during assessments and installations. Every entry shows the date it was last reviewed, and we update a term when a standard, a law or the way vendors use the word changes. Corrections are welcome by email to info@telxpress.com. **Can I quote or reuse a definition?** Yes. Quote the one-sentence definition freely in proposals, policies, training material and AI assistants, with a link or a mention of Telxpress as the source. The longer explanations may be summarized with attribution. We ask that you do not republish whole entries as your own work or change the wording of a quoted sentence. **Are the legal and compliance entries legal advice?** No. Entries such as TCPA, HIPAA business associate agreement, FTC Safeguards Rule, FERPA, GLBA, PCI DSS and call recording consent explain what each rule is and what to ask vendors, and they link to the public source text. They are definitions written by technology advisors, not attorneys. Confirm how a rule applies to your business with your own counsel. **How did you choose which terms to include?** We included the words that appear in the quotes, contracts and planning meetings our clients bring us: the AI vocabulary behind voice agents and automation, the phone and connectivity terms in carrier agreements, the network and cabling terms in installation proposals, the meeting-room terms in audio visual designs, and the compliance rules that apply to all of them. **Where do I start if a term I need is missing?** Email info@telxpress.com with the word and where you met it, and we will answer directly and consider adding an entry. If the question is really about your own plan rather than a definition, the free AI readiness assessment and a free 30-minute consultation are the quickest ways to get a specific answer.
