A local conferencing exchange subscriber line conferencing method using a series
of input signals from the phone of a subscriber, such as a dual-tone multifrequency
(DTMF) sequence of key inputs starting with a star key input, to initiate the conference
by enabling a termination attempt trigger. The conference is set up in a bridge
and the phone of the subscriber is connected to the bridge. All subsequent callers
to the subscriber's phone number at the local exchange carrier are routed and connected
to the conference at the bridge. When the conference call ends, the subscriber's
phone is returned to normal service.
