7.7.3.4.2 Call Forwarding
A fundamental function of the Hybrid system is the possibility of call for-
warding. The call forwarding is implemented in the system. Special PABX
protocols are not used for this function. If a call is forwarded, the connection
will be established to the call fowarding destination via a pre-defined B chan-
nel (see CHAPTER 7.5.1.3, page 45). In the system, the caller line will be con-
nected internally to the line of the call forwarding target. Therefore, the caller
remains in the system. This provides the possibility of returning the caller to
the first line. During a call forwarding al least two 2 B channels are used.
Set the Enable Call Forwarding option to activate the call forwarding.
The first channel for the call forwarding is set via First B channel used for Call
Forwarding. For call forwarding the last channels of the system are always
used.
The numbers of the call forwarding channels are fixed via the Number sub-
menu.
The required number of call forwarding channels depends on your applica-
tion. E.g. for a ’Call-In’ show where the audience is allowed to ask questions,
two screening positions are scheduled. These screening positions enter the
caller’s data and provide it for the presenter. The screening is made directly
by the Telephone Hybrid system (see CHAPTER 6, page 35). Accordingly, at
least two call forwarding channels are essential. If the show host forwards the
call e.g. to an editor after the talk, a third channel is necessary.
Via the 1st. telephone number for Call Forwarding and 2nd. telephone number
for Call Forwarding submenu two call forwarding targets can be established.
The Name that can be entered with each call forwarding is displayed by the
Forw. Call key (see CHAPTER 7.5.1.3, page 45) of the MAGIC TOUCH user
interface.

Normally this option should be active to avoid an irritatiing the presenter be-
cause of error messages. Especially PABXs tend to produce error messages
which are not relevant for the operation.
However, when starting the operation these error messages can be quite use-
ful to find the error.

The numbers in brackets show how many B channels can be used.

If the Telephone Hybrid is operated through a PABX, the Prefix Numbers (see
CHAPTER 7.7.3.4.3, page 75) can be suppressed for internal calls using a mi-
nus sign (’-’). For this function, the PABX telephone number must be entered
with a prefix ’-’ (Example: the PABX 130 must be entered as ’-130’).
L
If no telephone number is entered the manual call dialog or the telephone
book are opened automatically (depending on the Miscellaneous Settings
(see CHAPTER 7.7.3.1.8, page 68). Therefore, a temporary call forwarding to
any destination is possible.
This possibility is quite useful for the second call forwarding destination. To
keep this function better in mind enter as name e.g. „manual“.
