Protect Your Privacy:

The DTC provides several services that will assist you in protecting your privacy.

Caller Number ID– This service lets you see the number of an incoming call, even if it is non-published, using a display box (purchased separately) that attaches to your telephone.

Anonymous Call Rejection– This service rejects callers who have chosen to block their number from being displayed on your Caller Number ID device. Rejected callers receive a recorded announcement informing them of your wish not to receive calls from callers that have chosen to block their number.

Per-Call Blocking– Prevents your number from being displayed on a Caller ID device for one (1) telephone call.

All-Call Blocking- Prevents your number from being displayed on a Caller ID device for every call you make.

Selective Call Acceptance- You program a list of phone numbers you want to accept – all other calls are blocked.
