Configuring the interface mapping tables
327
SmartWare Software Configuration Guide
27 • CS interface configuration
to another user agent having a different URI than the called one. This new URI as well as the derived E.164
number cannot be manipulated using the call router before presenting it to the other party.
To circumvent this limitation, you can use mapping tables directly on an interface. In that case the mapping
tables can be thought as input or output filters, which manipulate call properties at any stage of a call.
As with the SIP transfer example, differentiating called from calling party properties does not make sense for
these manipulations, because the calling as well as the called party can be transferred in a SIP call. Therefore,
mapping tables that are used on an interface manipulate both at the same time, called and calling party proper-
ties!
You can chose different mapping tables for filtering parameters in each direction, input and output. While an
input mapping table is applied to all properties that are received by the port or gateway that is bound to the
interface before sending them to the peer interface in the CS context, an output mapping table is applied to all
properties before sending them to the bound port or gateway.
Refer to the chapter 33, “Call router configuration” on page 381 for more information about how to create and
configure mapping tables.
Procedure: To use mapping tables to filter properties on an CS interface
Mode: Context CS
Example: Use interface mapping tables for dialing plan conversion
The following example shows how to configure a dialing plan conversion on an interface. In this case, you can
plan your call-routing tables to deal only with international numbers while converting private numbers on the
CS interface that interfaces the private network.
node(ctx-cs)[switch]#mapping-table e164 to e164 PRIV-TO-GLOB
node(map-tab)[PRIV-TO~]#map (..) to 00419988825\1
node(map-tab)[PRIV-TO~]#exit
node(ctx-cs)[switch]#mapping-table e164 to e164 GLOB-TO-PRIV
node(map-tab)[GLOB-TO~]#map 00419988825(..) to \1
node(map-tab)[GLOB-TO~]#exit
