Add Allowed Numbers
Add trusted phone numbers that are allowed to call a subscriber.
Prerequisites:
- Bearer token —
POST /v1.0/oauth2/tokens - Subscriber ID and an existing
CallFilterId(CFID-) - Filter is in
WHITELISTmode for the allow list to actively gate callers (in other modes, the list is informational)
What this does: Adds one or more phone numbers to the allowed callers list. In WHITELIST mode, only numbers on this list can ring the subscriber — all others are blocked or sent to voicemail. Common use case: family members, doctors, or known business contacts.
Next steps:
- Verify the addition —
GET /v1.0/subscribers/call-filter/allowed-numbers - Undo —
POST /v1.0/subscribers/call-filter/allowed-numbers/remove
