# Get Active Call by Phone

Find the active call (if any) between an agent and a specific phone number. Useful for de-duplication checks before placing a new call, or to look up the call ID associated with an inbound caller.

```

## Path parameters

<ParamField path="agent_id" type="string" required>Agent UUID.</ParamField>

<ParamField path="phone" type="string" required>
  Phone number in E.164 format (e.g., `+15551234567`). URL-encode the `+` sign as `%2B`.
</ParamField>

## Request headers

<ParamField header="Authorization" type="string" required>
  Bearer token. Format: `Bearer talq_your_environment_token_here`
</ParamField>

## Notes

* Only calls with status `initiated`, `ringing`, or `answered` are considered active.
* If multiple active calls exist (rare — typically only one), all are returned in the array.
* For historical lookups, use [List Calls](/api-reference/endpoints/list-calls) with `to` filter.
