Selective Call Acceptance & Rejection
The selective call acceptance allows controlling incoming calls by making a list of telephone numbers which you are ready to accept. But incoming calls from subscribers that are not listed are directed to the answering machine by which the caller is informed that you do not accept calls at the moment.
This is a combination of several message transfer forms (SMS, fax, voicemail, video chat) into one interface available on several sets.
