Voice calls

After the first call is established, place an incoming call to the ISDN
BRI terminal.

Hold the first call and answer the second call.

Press the Conference key; the second call is put on hold.

Retrieve the first call and press the Conference key again. All three
parties should be in a conference.

Press the RELEASE key to drop from the call. The ISDN BRI user
should be disconnected from the conference; the remaining two
parties should still be connected, except for two outgoing trunk calls,
in which case all parties should be disconnected.

ISDN BRI Special Hunting

ISDN BRI Special Hunting allows a call encountering a destination that has
a call in progress to be automatically routed to a different destination in a
hunt chain. Hunting continues along a predetermined sequence of DNs in a
hunting group until an idle ISDN BRI or non-ISDN BRI terminal DN is found
or until the maximum number of hunt steps is exhausted. Use LD 27 to
define the hunting DNs in the DSL. See "DSL configuration procedures" in
ISDN Basic Rate Interface Feature Fundamentals (NN43001-580).

Special hunting for ISDN BRI supports calls terminating at an ISDN BRI
terminal. This feature is activated when a call terminating at a DSL
encounters a busy condition and if hunting is enabled. Internal and external
hunt DNs can be specified when configuring the DSL.

A busy condition occurs:

•

if the maximum number of calls on a DSL exceeds the specified limit of
calls on a DSL including active, calls held, calls waiting, and calls in
progression (as configured on LD 27), or

•

if the total number of calls including active, calls held, calls waiting, and
calls in progress exceeds the number of channels configured to handle
the incoming call type.

If the call limit on a DSL is not exceeded, an incoming call is presented to
the DSL interface as a call waiting call. If Hunting is enabled, the call will be
hunted.

Use LD 27 to enable or disable Hunting when configuring the TSP for the
ISDN BRI terminal DN. See "TSP configuration procedures" in ISDN Basic
Rate Interface Feature Fundamentals (NN43001-580).
