Call Screening

Call Screening allows the ISU 512 to answer all incoming calls (default) or only calls originating from phone numbers stored in the DIAL menu as stored numbers SN0 through SN9. See the section Dial Options for reviewing and storing numbers. Use the following menu path to configure Call Screening op- tions:

3=CONFIG 1=Netw. options

1=Dial Line 7=Call Screening

1=Answer any (default) 2=Answer if SN0..9

When Call Screening is set to answer any numbers stored in SN0 through SN9, an incoming call is not answered if the Call ID received from the switch does not match a stored number. Depending on the switch type, the Call ID may be presented in either a seven-digit or ten-digit format. The ISU 512 dis- plays the Call ID for all dumped calls in the Status buffer. See the appendix Status Buffer Messages for more information on the Status buffer.

Because different switches handle calls and Call ID differently, use the follow- ing procedure to determine if your switch uses a seven-digit or ten-digit Call ID format/Call ID (phone number).

1.Select Ansr if SN0. . .9 under Call Screening.

2.Store your multi-digit number in SN0.
