Call center glossary
Every term an operator runs into, from abandonment rate to wrap-up code — defined in plain language, with the formula where one exists.

In short
The DialedIn resource library is a free, ungated reference set for people who run contact centers. It covers nine areas: terminology, performance benchmarks, KPI definitions and formulas, dialing strategy, regulatory compliance, implementation, CRM integration, AI in the contact center, and platform comparisons.
Start with the glossary if the vocabulary is new, or the benchmark tables if you need to know whether your numbers are healthy.
Browse the library
Nine categories. Each one is a hub page with its own set of individual guides underneath it.
Call center benchmarks
What good looks like in 2026 — service level, AHT, FCR, occupancy, abandonment, cost per contact — with median and top-quartile figures by vertical.
Call center KPI guides
One guide per metric: what it measures, how to calculate it, what breaks it, and which other metric you have to read next to it to avoid gaming yourself.
Dialing guides
Predictive, progressive, preview and power dialing compared. Pacing ratios, answering machine detection, caller ID rotation, and list segmentation that actually connects.
Compliance guides
TCPA, the Telemarketing Sales Rule, state mini-TCPAs, STIR/SHAKEN, DNC scrubbing, HIPAA and PCI in the contact center — current as of 2026, with dates.
Implementation guides
Go-live sequences that hold up: number provisioning, campaign and queue design, IVR trees, agent scripting, QA calibration, and week-one troubleshooting.
CRM integration guides
Connecting the dialer to Salesforce, HubSpot, Microsoft Dynamics, Zoho and Zendesk: field mapping, click-to-call, screen pop, disposition sync, two-way write-back.
AI call center guides
Where AI earns its keep and where it does not: voice agents, real-time agent assist, automated QA scoring, sentiment, forecasting — plus how to measure containment honestly.
Comparison guides
Honest side-by-sides of contact center platforms and dialer types, including where competitors are the better fit. Evaluation criteria and an RFP checklist you can reuse.
Start here: the five questions we get most
Short answers with links to the full guide behind each one.
What is a call center resource library?
A structured collection of reference material for contact center operators — definitions, performance benchmarks, regulatory guidance and step-by-step operational guides. This one is organized into nine categories and is entirely free; none of it is gated behind a form.
What is a good first call resolution rate?
Industry-average FCR sits at roughly 70–74%, and above 80% is top-tier. It varies by vertical: retail runs near 78%, healthcare near 71%, financial services in the 67–71% band.
Read FCR next to average handle time. Driving AHT down by rushing calls usually pushes FCR down too, and next week's repeat volume up. Full FCR guide →
What is the difference between a predictive and a progressive dialer?
A predictive dialer forecasts agent availability and dials several numbers per available agent at once. It maximizes talk time, at the cost of some abandoned calls. A progressive dialer dials one number per agent only once that agent is free, which removes abandonment risk but produces fewer connects per hour.
Predictive suits high-volume lists with clean data. Progressive suits smaller lists, regulated verticals and higher-value conversations. Compare all four dialer types →
Is the FCC one-to-one consent rule still in effect?
No. The Eleventh Circuit vacated it on January 24, 2025 in Insurance Marketing Coalition Ltd. v. FCC, holding that the Commission had exceeded its TCPA authority, and the FCC formally removed the nullified rule in July 2025. It never took effect.
Plenty of operators still capture seller-specific consent anyway, because it is easier to prove in litigation and it removes the lead-source ambiguity that causes most disputes. General information only, not legal advice. Current TCPA guide →
How long does it take to implement cloud call center software?
A single-campaign outbound deployment can be live in a day, because there is no hardware to provision. Timelines stretch to two to six weeks when the project includes CRM field mapping, historical data migration, custom IVR trees, SSO or multi-site workforce management.
The gating factor is rarely the software. It is list hygiene, integration scope and agent training throughput. Implementation guides →
Most-used pages
How this library is maintained
Every page carries a published date, a last-reviewed date and a named reviewer. Benchmark figures cite their source and the period they cover, because a 2023 number presented as current is worse than no number. Compliance pages are re-reviewed each quarter and note the effective dates of the rules they describe — those dates have moved more than once, and a guide that doesn't say when it was checked isn't usable.
Where a competitor's product is a better fit for a particular use case, the comparison guides say so. Found something out of date or wrong? Tell us and we will fix it and note the change.
