ISDN Outgoing Calling
56 Strata DK Digital Telephone 10/01
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 DK424i, DK424
with software Release 4.0 or higher, or DK40i, 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.
