Alternative Routing (Fallback Routing)
If the LCR function realizes that access to the network provider initially selected is
not possible, a call is routed to the alternative network provider and an event mes-
sage is generated ("LCR via alternative network provider").
The LCR function recognizes that access to a network provider is not possible if,
• all the B channels in the selected route are busy,
• routing via the primary network provider is barred in the network provider
table,
• the network signals to the PBX that the primary network provider is not avail-
able (e.g. due to overloading).
Manual alternative Routing
In some situations the LCR function cannot recognize that the primary network
provider is not available (for example if the network provider answers the call with
a voice message). The user then has the possibility to dial via the alternative net-
work provider manually. To do so he interrupts the connection and dials *90. The
number is then redialled in the same way as with a last-number redial but this time
via the alternative network provider.
If the user routes a call via the alternative network provider manually, no event
message will be generated.
If users are not to be authorized to dial the alternative network provider them-
selves, *90 should be barred in the internal digit barring.
Manual alternative routing also works if automatic alternative routing is not acti-
vated.
