using busy keys on the system network (see PBX Networking starting on
page 228). Please note the following points:
● Busy key information can be transferred via all connection types of a PBX
system networking: Q.SIG-ISDN, Q.SIG-IP and SIP-Tie-Line. The
Protocol
extension option has to be activated in the bundle configuration for Q.SIG-
ISDN.
● Busy keys only work between communications systems Forum 500 /
5000 with a system software version from Release 7 or higher.
● If there are multiple lines available in a bundle for PBX system networking,
one of the lines is selected for busy-key signalling. If this line fails, it can
take a few minutes until the dynamic subscriber list is updated.
Note: The “call number busy” busy-key function is the only one
supported for PBX system networking. The “device busy” busy-
key function is not supported by PBX system networking.
PIN Code Telephony
The users in a company normally use the existing terminals primarily for
company-related communication. Now the users would like to also be able to
make private calls in some cases. Private calls require:
● seizure of special external lines,
● changed and valid authorisations,
● recording separate charges and
●
that destination call numbers not be saved for redialling.
This function can be realised using the “PIN Code Telephony” feature. To
initiate a special call, the user on any terminal uses a special menu function or
code procedure. After the user enters his/her own internal call number and
associated user PIN, the desired attributes for the next call are activated.
When the call is finished, the previously active telephone configuration is
restored. This external call number dialled is not recorded in a redial list.
