# Get Call Filters

> List the call filters configured on a subscriber or phone number.

**Prerequisites:**
- Bearer token — `POST /v1.0/oauth2/tokens`
- Subscriber ID or phone number to filter by (otherwise returns all)

**What this does:** Returns the full configuration of each matching filter — mode, allowed/blocked number lists, transcription settings, and keyword alert rules. Use this to audit a subscriber's call controls or to find the `CallFilterId` (`CFID-`) you need for subsequent calls.

**Next steps:**
- Inspect allowed/blocked lists in detail — `GET /v1.0/subscribers/call-filter/allowed-numbers`, `GET /v1.0/subscribers/call-filter/blocked-numbers`
- View keyword rules — `GET /v1.0/subscribers/call-filter/keywords`
- Modify a filter — `POST /v1.0/subscribers/call-filter/update`
- Remove a filter — `POST /v1.0/subscribers/call-filter/delete`
