Outbound Dialer & Contact Center Glossary
Clear, plain-English definitions of the terms outbound teams, BPOs, collections, and telecom resellers use every day — from dialing modes to compliance and telephony.
Quick answer
This glossary defines the core outbound calling and contact center terms — the four dialing modes (preview, progressive, power, predictive), answering machine detection (AMD), BYOC and SIP trunking, IVR, and Do Not Call (DNC) compliance — with links to a deeper explainer for each.
Answering Machine Detection (AMD)
How AMD detects voicemail vs live humans — and why transcript-based AI beats legacy beep detection.

The umbrella term for systems that dial automatically — preview, progressive, power, and predictive.
Read definition →BYOC (Bring Your Own Carrier)
Connecting your own SIP trunks to a platform instead of using bundled telephony.
Read definition →Do Not Call (DNC) List
Registries and internal lists of numbers that must be suppressed before dialing.
