Rejecting a call
You get an external call or you are making a call and receive an external call. The call is
signalled acoustically and also shown in the display on all telephones or handsets in this
MSN group. You can reject this external call.
Press the display key
REJECT
.
Depending on the setting (page 96) the call can be rejected on the base station rejecting
the call only (telephones or handsets with the same receive MSN continue to ring) or it
can be rejected for the entire MSN group (the caller hears the busy tone).
Reserving a line
Your ISDN connection offers you 2 simultaneously usable telephone lines (B channels).
Precondition: You want to make calls externally, but both telephone lines of your
connection are busy (being used by other internal users).
Press the display key
CALLBCK
. The next available free line will be reserved for you.
You base station rings as soon as an external line is free.
Defining the send MSN for the next call
Even if you have defined an individual send MSN for the base station (page 94), you can
select another MSN as the send MSN before each call, e.g. for individual recording of
charges.
Make sure that the send/receive MSN corresponds to the phone number registered at
your SMS centre (page 47).
By factory default, MSN next call
is not activated for an MSN.
