User-specific configuration
The settings described in the last section can also be configured individually for 
each user. The user-specific configuration takes priority over the setting for the sys-
tem as a whole. If a user’s settings are not to deviate from the settings made for the 
system as a whole, the parameter has to be configured to According to exchange 
settings (initialization value).
Specially configured abbreviated dialling numbers
Exchange-to-exchange traffic can be enabled in general for specially configured di-
rect dialling numbers (Exchange-to-Exchange Connection = Ye s). This allows all 
types of exchange-to-exchange connections, and is also valid in cases where ex-
change-to-exchange traffic is barred in the system configuration and the user-spe-
cific configuration. The abbreviated dialling number stored does not have to be 
complete, which means digits can be suffix-dialled manually. This allows for exam-
ple exchange-to-exchange traffic to be enabled for an entire office branch using a 
single abbreviated dialling number.
