Chapter 5: Configuration
Connect Timeout
The Connect Timout option sets the length of time that the ISU 512 waits for
a far-end unit to answer an outgoing call. Use the following menu path:
3=CONFIG
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
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).
