Call Routing
2.157
5.4.2 LCR Function
To be able to make outgoing phone calls, a PBX subscriber normally dials an
exchange access prefix first.
If the LCR function is deactivated the PBX routes the call in accordance with the
exchange access prefix dialled (see "Exchange access authorization",
Page 2.148).
If the LCR function is activated and able to analyse the phone number dialled, the
phone number will be routed in accordance with the configured LCR criteria. The
exchange access prefix is not analysed by the LCR function.
The LCR function can be activated or deactivated throughout the system. If it is
activated, it can be deactivated for individual subscribers.
