C
Call diversion during the call phase
CD, Call Deflection. Must be explicitly enabled by the network provider for each ISDN
connection. CD enables an incoming call to be forwarded to any phone number
while it is ringing, without having to answer the call. Because the caller has no affect
on where it is forwarded (for example, to a mobile phone), you will pay the resulting
charges. The caller must only pay the normal telephone charges for the connection
he dialled.
Call forwarding
CF, Call Forwarding. You want to forward calls to another number permanently.
You can forward calls externally via the exchange or internally in the device itself.
Call forwarding can be set up individually for each separate phone number (MSN)
(to your mobile phone when on holiday, to the office, to a neighbour etc.).
This is carried out at the network provider's local exchange. This means the call
never reaches the original destination.
There are three kinds of call forwarding:immediate (CFU, Call Forwarding
Unconditional), when the line is busy (CFB, Call Forwarding Busy), and when the call
is not answered (CFNR, Call Forwarding No Reply).
Call diversion (via the second B-channel) / internal call diversion
While external call diversion takes place in the local telephone exchange of the
network provider, internal call diversion is implemented by your telephone.Your
telephone forwards the call via the second line of your ISDN connection. This means
both phone lines are engaged for the duration of the call
. You pay the charges
for the connection to the forwarding number. However, you save yourself the
network provider's charges for this function.
Call waiting
CW, Call Waiting. Service provided by the network provider. An acoustic signal
during a call indicates that another caller is waiting. In addition, ISDN phones
indicate this with a displayed message. You can then decide whether to accept or
reject the second call.
Call waiting protection
Deactivates the call waiting signal.
Callback on busy
Callback must first be activated on the caller's terminal. A connection is established
automatically as soon as the destination phone is no longer busy. As soon as the
connection is free the caller is rung back. As soon as the caller lifts his receiver the
connection is made automatically.
Caller identification
Displays caller's phone number, name or type of connection (e.g., exchange/
internal) on the telephone screen.
