Can we activate Call Protect (1572) without activating the standard voicemail (1571)?
Also, can we have the standard voicemail without it picking up the calls when the line is engaged? At the moment my door bell calls my landline and I can use the handset to answer and release the door. But when the landline is engaged, it calls my mobile number. With standard voicemail on the landline, this second call will never be made.
