4.1.1 Spontaneous call management by the user
Functions for spontaneous call management
Calls can be managed on an individual basis and the LANCOM
Business-VoIP-Router supports the services known from the ISDN network:
With call hold the user can place an active call into a wait state. In this
state, the user can for example make a call to another person.
Establishing an additional call while a call is on hold is referred to as
consulting . This call can be ended again and the conversation with the
call on hold continued.
With swap call , the user can switch to and fro between two connections.
The user is only connected with one caller at a time, while the other caller
is put on hold.
With call transfer ("connect call") the user switches an active call over to
another call which is on hold. The two callers are then connected and the
user is no longer involved in the call. A subscriber transferring a call can
either directly hand over an active call to a third subscriber (unattended
call transfer), or a separate call can be made to the third subscriber to
communicate the call and then transfer it (attended call transfer).
Using spontaneous call management with various telephones
SIP telephones and SIP softphones generally feature special keys or menu
entries to manage calls. Depending on the model or program, different terms
may be used the the functions are as follows:
HOLD: Places an active call into a wait mode or swaps between two active
calls. On ISDN and analog telephones this function is often referred to as
the F-key/Flash/Call hold.
HANG UP: End the current call.
SWAP: Swap between two active calls (depending on the ISDN telephone,
this may be initiated by a display-menu entry, a special key, or the "F"
key).
CONNECT: Initiates the call's transfer (can be triggered by "hanging-up"
with an active call and a call on hold)*.
