# Filter Calls

Burki does not expose a separate full-text `/calls/search` endpoint. Use the [List Calls](/api-reference/calls/list) endpoint with filter query parameters to find calls by phone number, call SID, assistant name, status, assistant, date range, or duration.

### Query Parameters

* `customer_phone` (string, optional): Filter by customer phone number. Partial matches are supported after phone normalization.
* `call_sid` (string, optional): Filter by Burki call SID / provider call identifier. Partial matches are supported.
* `assistant_name` (string, optional): Filter by assistant name. Partial matches are supported, including deleted-assistant snapshots.
* `status` (string, optional): Filter by call status.
* `assistant_id` (integer, optional): Filter by assistant ID.
* `date_from` (string, optional): Filter calls started on or after this ISO timestamp.
* `date_to` (string, optional): Filter calls started on or before this ISO timestamp.
* `skip` (integer, optional, default: 0): Number of records to skip.
* `limit` (integer, optional, default: 100): Maximum number of records to return.

Filters are combined with AND semantics.

### Response

The response is the same paginated object returned by the [List Calls](/api-reference/calls/list) endpoint.
