# DialNexa Calls Overview

> Understand DialNexa calls across phone numbers, inbound calls, outbound calls, web calls, call transfer, voicemail, SIP trunking, and call history.

DialNexa calls are the live conversations created by agents, phone numbers, batch campaigns, workflows, web calls, or manual tests. A call combines a route, a published agent version, a recipient or caller, and a call log that stores the evidence afterward.

## Get Your First Call Working

New to calls? The fastest path from zero to a live conversation:

<Steps>
  <Step title="Get a number">
    [Buy a number](/calls/phone-numbers) or [link your own via SIP trunking](/calls/sip-trunking). Outbound calling also requires [KYC verification](/platform/kyc-and-outbound-readiness).
  </Step>

  <Step title="Point it at a published agent">
    Assign a published agent version to the number for [inbound answering](/calls/inbound-calls), or place a [single outbound call](/calls/outbound-calls).
  </Step>

  <Step title="Verify in Call History">
    Open [Call History](/monitoring/call-history) and confirm the status, transcript, and recording match what you expected.
  </Step>
</Steps>

<Note>
  A call is not complete when it rings. It is complete when you can explain what happened afterward.

## Call Entry Points

Different product surfaces create different kinds of call records.

| Entry point        | How it starts                                                                    | Where to review                        |
| ------------------ | -------------------------------------------------------------------------------- | -------------------------------------- |
| Inbound call       | A caller dials a DialNexa number assigned to an inbound agent version.           | Call History                           |
| Outbound call      | A user or API starts a single call through an outbound number and agent version. | Call History                           |
| Batch call         | A campaign calls many recipients from a CSV file.                                | Batch Calls and Call History           |
| Workflow call node | A workflow lead reaches a Voice Call node.                                       | Workflow lead history and Call History |
| Web call           | A browser or web experience starts a web-type call.                              | Call History                           |

## The Route Decides The Agent

Routing is the first thing to check when a call uses the wrong behavior.
