280 Call Routing Part 2
5.2.3.1 Response if the call destination is busy
If the call destination is busy, an incoming call will be handled according to the
type of destination. Busy call destinations may be:
• An individual, busy subscriber
• A busy user group
• A busy KT line
• A subscriber with a stored message
• A user group with busy subscribers but without the elements Operator console
and General bell.
Within the context of this Chapter a call destination is said to be busy if both he
original destination and the alternative destinations, where configured, as busy
(setting "CDE if busy").
Call destination: Individual, busy Subscriber
Call waiting allowed but is rejected
• In the case of an incoming call from the public ISDN network the caller obtains
the busy tone.
• In the case of an incoming call from the private leased-line network call waiting
is not possible.
• In the case of an incoming call from the public analogue network call waiting
is repeated.
Call waiting not allowed or not possible
If no alternative destinations have been configured, the following rules apply:
• In the case of an incoming call from the public ISDN network the caller obtains
the busy tone.
If the caller has subscribed to the service "Automatic callback (CCBS)" with the
network operator, he can activate that service.
• In the case of an incoming call from the private leased-line network the caller
obtains the busy tone.
• In the case of an incoming call from the public analogue network the caller
waits until the called party is free (polling).
