The Trusted Callers Only Profile gives the maximum protection against unwanted calls. If the caller’s number is on the Trusted Callers list the phone rings as normal, all other callers hear the screening announcement, and can only get through if they know the Callers Code.
If you select the Trusted Callers Only Profile we strongly recommend that you record a personal screening announcement - for example:-
“Hello, Mary only accepts calls from friends and family members. If you need to get through to her, please hang up and call her son John on 07767 xxxxxx – that’s John on 07767 xxxxxx – or enter your code now. Thank you”.
Anyone who calls who has a legitimate interest in contacting Mary will be able to call John. Telemarketers and scammers will not do this.
Alternatively you could be more cautious and not give out the full number:-
“Hello, Mary only accepts calls from friends and family members. If you need to get through to her please hangup and call her son John on his mobile number ending 212, or enter your code now - Thank you”.
