## Your phone system. Connected through Bird.

Bring your PBX or SIP client. Set the direction, authenticate the connection, and choose where calls can go.

Illustrative SIP configuration. No trunk settings change and no call is placed.
[Caller IDs](/docs/guides/voice/caller-ids)[Incoming calls](/docs/guides/voice/receiving-calls)
[Explore SIP trunks](/voice-api/features/sip-trunking)

## Your calls. In your workflow.

Read current call activity from your app or agent. Inspect call records with MCP, CLI, SDKs or REST.

**MCP**: `Bird MCP`

Connect this hosted MCP endpoint with an [MCP client](/docs/ai/mcp-server#connect-a-client), then complete OAuth sign-in to your Bird workspace.

Example prompt: Can you check which calls are active right now and tell me which are connected and which are still ringing?

Examples: [MCP](/voice-api.mcp.md) · [CLI](/voice-api.cli.md) · [TypeScript](/voice-api.ts.md) · [Python](/voice-api.py.md) · [Go](/voice-api.go.md) · [PHP](/voice-api.php.md) · [cURL](/voice-api.curl.md)

## A clear path. For every caller.

Greet the caller, collect a keypad choice, and follow the selected branch. Try 1 or 2 to read the response in the transcript.

[Explore call sequences](/voice-api/features/call-sequences)

## Every call. A reason you can inspect.

See when a call rang, when it connected, and how it ended. Keep answered time separate from the total duration.

Illustrative completed call records. Outcome controls inspect different examples; they do not place or retry calls.
[Explore Voice events](/docs/guides/voice/events)[Explore the call log](/docs/guides/voice/call-log)

## Call volume. With the context behind it.

Follow answer rates to a specific destination.
