*In some cases, SIP or ISDN telephones can be configured so that
hanging-up the handset either causes the consultation or active call
or be terminated, or a call transfer is triggered ("Connect").
4.1.2
Configure permanent call forwarding
Along with spontaneous call transfers as controlled by a subscriber during a
call ("connect call", it is often useful to set up a permanent call forwarding
("redirect calls"). For example, a call should be forwarded when a line is busy,
if there is no answer within a certain period, or in case of absence (e.g.
vacation).
There are two possibilities for configuring permanent call forwarding.
Via the telephone or terminal device itself with the aid of control
characters
In the configuration of the LANCOM Business-VoIP-Router by means of
the management tools (LANconfig, WEBconfig or telnet)
If permanent call forwarding is activated by both methods, then the
behavior of the call forwarding follows the last respective action.
Dial the number for the second caller while the first call is on hold.
If you cannot reach the second caller, you can return to the call which is on
hold by pressing the hold key.

As soon as you have established two simultaneous connections you can
connect the two callers with the connect key (or 'F' and '4' on analog
phones) or by hanging up the handset.*
Optionally you can switch between the two lines as often as you like
before transferring. Call transfer always connects the active call and the
call on hold.
