Call diversion (via second B channel / internal call diversion
While external call diversion takes place in the network provider's local telephone
exchange, internal call diversion is implemented by your telephone. Your telephone
diverts 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 forwarding CF
CF, Call Forwarding. You want to forward calls to another number permanently.
You can divert calls externally via the exchange or internally in the device itself.
Call diversion (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 types of call diversion: immediate (CFU, Call Forwarding
Unconditional), when busy (CFB, Call Forwarding Busy) and on no answer
(CFNR, Call Forwarding No Reply).
Call forwarding 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 to the connection
he dialled.
Call transfer (e.g., for ISDN PABX's)
ECT, Explicit Call Transfer. User A calls User B. He puts the connection on hold and
calls User C. Rather than connect everyone in a three-party conference, A now
transfers User B to C and hangs up.
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.
