Call routing
231
System functions and features as of R3.0
syd-0367/1.3 – R3.0 – 03.2013
6. 6. 4. 1 Time zones
The time zones are used to allocate network providers depending on the time of 
day. This means it is possible to take account of the fact that network provider  3 for 
example is more cost effective at night than network provider  2 
If the time at which a connection is set up is outside the defined time zones the call 
is routed in accordance with the user configuration (without LCR function).
If the time indications of several time zones overlap, the time zone placed further 
up in the table applies to the area of overlap:
