2.16.4 Net Call Forward - Unconditional
Description
It is possible for a user to forward his station remotely and immediately over the network when it
receives a ring signal.
Engineering notice)
There are two kinds of standard net call forward signaling method in H.450 protocol specification
defined; JOIN and REROUTING. The main difference is how the connecting path among the
forwarding, forwarded, forwarded-to stations controls.
The term of forwarded station is the call originator. The forwarded station is rerouted to the forwarded-
to station by forwarding station. In the figure 2.16.4, the outside caller is the forwarded station.
The term of forwarded-to station is the new destination of the forwarded call. In the figure 2.16.4, the
station 202 is the forwarded-to station.
And the term of forwarding station is a station forwarding a call, to forwarded-to station. In the figure
2.16.4, the station 100 is the forwarding station.
IP LDK system supports both JOIN and REROUTING. The signaling method can be selected by
ADMIN program 321 – FLEX 1.
The figure 2.16.4 describes the unconditional net call forward operation on the networking connection
environment. At the first step, the station 100 is set the unconditional net call forward to the
forwarded-to destination 202. At the second step, the outside caller is dialed the telephone number of
station 100. At the third step, the networking system of station 100 is forwarding the incoming call to
station 202, that is located the another networking system. At the fourth step, station 202 is receiving
a ring signal from the outside caller. After answering, station 202 can make a conversion with the call
forwarded caller at the fifth step.
