CallBolt glossary

Updated September 2026

AI voice and support terms, defined plainly: what each one means, how it works, and how Sky does it.

The terms

Every definition on the site, from the manifest.

  • AI voice agent

    An AI voice agent holds spoken phone conversations and completes the caller's request in your systems. The definition, how it works, and how Sky does it.

  • AI receptionist

    An AI receptionist answers your business phone like a front desk: greets callers, books appointments, answers questions, transfers urgent calls.

  • AI answering service

    An AI answering service answers your business phone with software instead of a staffed call desk, and completes the caller's request during the call.

  • AI phone agent

    An AI phone agent answers and places phone calls for your business, holding natural conversations and completing the task on each call.

  • IVR

    IVR is the phone menu that routes calls with recordings and keypad tones. What it is, why callers dislike it, and what replaces it.

  • Conversational AI

    Conversational AI holds natural-language conversations using language models instead of scripts. The definition and how Sky does it on calls and tickets.

  • Outbound calling

    Outbound calling is placing calls to your own customers and leads: reminders, confirmations, follow-ups and win-backs. The definition and how Sky runs it.

  • Warm transfer

    A warm transfer hands a call to a human with the context already delivered, so the caller never repeats themselves. The definition and how Sky does it.

  • Call deflection

    Call deflection moves routine contacts off the human queue by resolving them earlier. Done well it means resolved, not refused. The definition inside.

  • First-call resolution

    First-call resolution is the share of requests fully resolved in the first contact. The definition, why it matters, and how Sky is built for it.

  • Virtual receptionist

    A virtual receptionist answers your phone from off-site, either a remote human service or software. The definition, the AI difference, and how Sky does it.

  • Human-in-the-loop

    Human-in-the-loop is the design where software does the routine work and a person owns the judgment calls. The definition and how Sky does it.

  • Proactive outreach

    Proactive outreach is contacting customers before they contact you: reminders, quote follow-ups, win-backs. The definition and how Sky runs it.

  • Omnichannel support

    Omnichannel support is one customer conversation coherent across channels: the call, the ticket and the chat all know what the others said.

  • AI guardrails

    AI guardrails are the rules that bound what an agent may say and do: identity checks, tool allowances, gated money actions, audit trails.
