AI-Powered IVR / Conversational AI
An interactive voice response system that uses artificial intelligence to understand natural speech instead of requiring callers to press buttons. Instead of "Press 1 for sales," the caller can say "I want to speak to someone about my invoice" and the system routes them to the right department. Conversational AI uses speech recognition and natural language processing to handle routine requests without human agents.

AI Call Transcription
Automatic conversion of spoken words in a phone call into written text using AI. The transcription happens in real time or shortly after the call ends. It creates a searchable text record of every conversation, which is useful for compliance, training, and record-keeping. Modern transcription engines support multiple languages and can identify different speakers in the same call.

AI Call Summary
An AI-generated brief overview of a phone call, created automatically from the full transcription. Instead of reading a 30-minute transcript, a manager can read a 5-sentence summary that highlights the key topics, decisions, and action items. Call summaries save time and make it easier to review large volumes of calls.

Sentiment Analysis
AI technology that evaluates the emotional tone of a phone conversation. It analyses word choice, speech patterns, and tone to classify the call as positive, neutral, or negative. Call centre managers use sentiment analysis to identify unhappy customers, flag calls that need follow-up, and measure overall service quality without listening to every recording.

AI Agent / Virtual Agent
A software program powered by AI that can handle phone calls autonomously, without a human operator. AI agents can answer frequently asked questions, schedule appointments, process simple orders, and collect information before transferring to a human if needed. They operate 24/7 and can handle multiple calls simultaneously.

RCS (Rich Communication Services)
A messaging protocol designed to replace SMS with richer features: read receipts, typing indicators, group chats, high-resolution images, and interactive buttons. RCS is built into the default messaging apps on Android phones and is supported by Apple since iOS 18. Some Cloud PBX providers are beginning to offer RCS alongside voice and SMS.

eSIM for Business
An embedded SIM chip built into a phone or device that can be programmed remotely, without needing a physical SIM card. For businesses, eSIM simplifies mobile fleet management: IT can activate, switch, or deactivate mobile plans over the air. Combined with a Cloud PBX, eSIM enables seamless fixed-mobile convergence where desk and mobile numbers are managed from one platform.

5G and VoIP
The fifth generation of mobile network technology, offering significantly faster speeds, lower latency, and greater capacity than 4G. For VoIP, 5G means higher call quality on mobile devices, more reliable softphone connections, and the ability to support video calls and real-time collaboration without Wi-Fi. 5G makes mobile-first Cloud PBX usage practical even in demanding environments.

Edge Computing for VoIP
Processing voice data at network locations closer to the user (the "edge") instead of sending everything to a distant cloud data centre. By reducing the physical distance data must travel, edge computing lowers latency and improves call quality. Telecom providers are deploying edge servers in their 5G networks to support real-time voice and video applications.

CPaaS (Communications Platform as a Service)
A cloud platform that provides voice, messaging, and video capabilities as building blocks that developers can embed into their own applications using APIs. Instead of buying a full PBX, a business can use CPaaS to add click-to-call buttons to a website, send SMS appointment reminders from a booking system, or build a custom contact centre.
OpenTelemetry for VoIP
An open-source observability framework that collects performance data (traces, metrics, logs) from VoIP systems. It helps engineers monitor call quality, diagnose problems, and understand how calls flow through complex infrastructure. OpenTelemetry is becoming a standard for monitoring cloud-native applications, including modern Cloud PBX platforms.

SIPREC (SIP Recording)
A standard protocol for recording SIP-based calls by duplicating the audio stream and sending it to a dedicated recording server. SIPREC works alongside the live call without affecting audio quality. It is increasingly adopted by Cloud PBX providers because it separates the recording function from the call-handling system, improving both reliability and regulatory compliance.
VoNR / VoLTE (Voice over New Radio / Voice over LTE)
Technologies that carry voice calls natively over 4G (VoLTE) and 5G (VoNR) mobile networks instead of falling back to older 2G/3G circuits. VoLTE and VoNR deliver HD voice quality, faster call setup, and the ability to use voice and high-speed data simultaneously. As 3G networks shut down across Europe, VoLTE becomes essential for mobile voice service.
