# callId

> Call ID for this participant's leg, or undefined if not available.

```ts
get callId(): string | undefined
```

Call ID for this participant's leg, or `undefined` if not available.

This is the participant's *own* call context, not the local call's ID — a remote member on a bridged or auxiliary leg carries a different one, which is why member RPCs are addressed with [`target`](/docs/browser-sdk/v4/reference/participant/target) rather than the local call ID.

It is populated by the member's first full state event (`member.joined`, `member.updated`, or the `call.joined` roster).

## **Examples**

```ts
console.log(participant.callId);
```

## **See**

* [`target`](/docs/browser-sdk/v4/reference/participant/target) — the full RPC target triple built from this value.
