Directory Number Hunting
Is a telephony service allowing the distribution of telephone calls from one telephone number in the group consisting from several telephone lines, using the special algorithm, which determines the line receiving a call.
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.
