VoIP gateway IP400 version 5.01

Calls from different interfaces are often handled in the same way. In the scenario
illustrated by Fig. 22 on page 87 it may, for example, be desired to allow calls
from both TEL1 and TEL2. That is why a number of interfaces can be specified as
permitted sources for a route.
Of course, call switching often also depends on the call numbers dialled. That is
why it is necessary to define the validity of routes for calls with certain destination
numbers. This is done by attaching a so called
Map
entry to the route of each
valid dial prefix. Each map entry therefore determines that calls from the source
interfaces specified in the route with the combination of digits specified in the
map, can be connected to the destination interface defined in the route. Fig. 24
on page 89 shows such a scenario.

Sometimes it is useful to modify the called number in the course of call switching.
Fig. 25 on page 90 shows the configuration of such a scenario in the configuration
applet of your gateway. The MSNs (
529969
and
529096
) assigned to a point-
to-multipoint connection are mapped onto the internal extension numbers
20
and
30
.
