Making External/Internal Calls

Making Calls
Call Waiting with an Internal Subscriber
When you call an internal subscriber whose number is busy, your
call will appear on their display and signalled with the call waiting
tone. You hear the ringing tone yourself. The system administrator
can determine that a special ringing tone is used for call-waiting
calls. Based on this special ringing tone, you can decide whether
you wish to end the connection or not.
If the subscriber called has activated call-waiting protection (see
page 96) you will hear the busy signal. You can penetrate a sub-
scriber's call-waiting protection via a VIP call (see page 52).

The Forum 500 / Forum 5000 establishes calls to the desired sub-
scribers either automatically or via specific routes. Your system
administrator configures these routes in the Forum 500 /
Forum 5000 and specifies how each route is seized. In order to
manually seize a specific route for a call, you dial the routing code
before dialling the (internal or external) telephone number. By
making calls via specific routes, you can e.g. contact subscribers
in the branches of a large company network. It is also possible to
use a manually-entered routing code to record your call-charge
data for private and business external calls separately.
The
default route
“External line” is always present and cannot be
deleted. Automatic trunk line seizure uses the Forum 500 /
Forum 5000 trunk line seizure code digit for the default route.
For information on the current routes and their codes, please con-
tact your system administrator.
