# `bird voice session-credentials`

## Usage

```bash
bird voice session-credentials
```

## Description

A session credential is a SIP username and password that expires within minutes,
issued to your workspace rather than stored anywhere you have to protect. It stands
in for an API key secret when a SIP client authenticates, and only a trunk that
allows session credentials admits a call presenting one.

Mutations take flags and/or a --body-file JSON body (flags overriding); run --example to print the body shape or --dry-run to preview the request.
