Making External/Internal Calls
112 Telephoning
If the subscriber called has activated call-waiting protection (see page 157)
you will hear the busy signal. You can penetrate a subscriber’s call-waiting
protection via a VIP call (see page 105).
Information for the system administrator
The special ringing tone is defined in the Configurator > Telephony >
Settings menu ( Use special ring-back tone at call waiting setting).
Using Routes to Make Calls
The Forum 500 / Forum 5000 communications system sets up calls to the
desired subscribers either automatically or via specific routes. Your system
administrator configures these routes and specifies how each route is seized.
To manually seize a specific route for a call, you dial the routing code before
dialling the (internal or external) call number. Making calls via specific routes
enables you to contact subscribers in the branches of a large company
network, for example. You can also use a manually-entered routing code to
record your call-charge data for private and business external calls separately.
The default route External trunk is always present. Automatic line seizure
uses the line seizure code digit for the default route.
For information on the current routes and their codes, please contact your
system administrator.
Information for the system administrator
Routes are defined in the Configurator > Telephony > Trunks > Route menu.
Busy Display for Bundles (Trunk Groups) and
Routes
The SIP system telephones can display whether all lines (trunks) of a bundle
or a route are busy. To do this, a feature key
Trunk group state or Route state
must be programmed, see also the chapter Programming Keys on page 84.
