It is also possible to activate a rerouting from one VoIP provider to the next. If the first VoIP
provider is not available the calls will be routed to the next VoIP provider. You need two VoIP
providers in this case, configured as described in
Chapter 5.3.1 on page 47 . In Example 5.9
these will be PeerA for the first VoIP provider and PeerB for the second VoIP provider. If the
second provider is also not available the call will be routed to mobile.
5.5 Cost saving routing
This is a mapping similar to the rerouting described in the previous section. If it is possible to
reach a destination over different ports or numbers, create a route on the cheapest way first.
The next way is reachable with a rerouting.
Example 5.10 sends the calls from FXS to the destination 541867530 directly to the mobile
ports, not with the default routing in the next line to VoIP like all other normal traffic. The
first line overrides the default routing and sends the call directly to the mobile port instead of
the normal VoIP provider.
