ISDN Outgoing Calling
This feature enables you to make outgoing call using an Integrated Services Digital Network
(ISDN) trunk, provided that you are connected to a Strata DK424, DK40i, or DK40 system
with Release 4.0, or higher, and that you subscribe to ISDN lines. ISDN trunks offer faster call
connection setup, and they also provide more connection circuits.
Making an ISDN outgoing call will either be handled automatically with a timer or by you
initiating the ISDN “Start” sequence. The method depends on your system’s programming.
See your System Administrator to determine the method.
