6. 6. 4 Selecting the Network Provider (Routing Tables)
The routing tables are used to select a primary or an alternative network provider
for a categorized call, depending on the time of day and the weekday.
A total of 20 routing tables with up to 10 time zones each can be defined.
Tab. 63 Example of a routing table
Depending on the current zone a call will be routed to one of the following net-
work providers:
• Primary carrier
• Alternative network provider (alternative routing)
• Network provider in accordance with the user-specific routing (user configura-
tion)
The criteria for selecting one of these network providers are shown in Tab. 64.
Tab. 64 Selection of the network provider depending on settings and situation
If neither the network provider selected initially nor the alternative network pro-
vider is available, the call will be cleared down. The caller will obtain the congestion
tone.
Automatic alternative routing can be activated or deactivated throughout the sys-
tem.
