9.2.2 Using ISDN Supplementary Services
ISDN service providers may incorporate features similar
to those of Centrex. These ISDN Supplementary
services are provided on a subscription basis, and as
with Centrex, are accessed using the Flash button on
an iPECS phone.
Using supplementary services an ISDN line can be
placed on Hold and a second call placed on the line.
You may then alternate between the two held calls
(Broker Call) using the hold button. An ISDN line
conference can be established using the Flash
and
Conf Soft buttons. A conference can also be placed on
hold.
