Figure 53. Incoming call passing an interface mapping table

Figure 53 shows two incoming calls arriving to the ISDN interface IF-PHONES. The calling and called party numbers are private numbers containing only two digits. Before accessing the call router, those numbers can be transformed into the global numbering plan. Which is why the interface was configured to use mapping table PRIV-TO-GLOB on all incoming call properties.

Incoming call #1 originally has a calling party number of 20 and a called party number of 21. Before offering this call to the call router, mapping table PRIV-TO-GLOB is applied to the called party number and the call- ing party number. The mapping table adds a prefix of 00419988825 to the called and calling party number.

Incoming call #2 originally has a calling party number of 20 but already a called party number of the global numbering plan. Again, the mapping table is applied to both number, but only the calling party number of 20 is translated into 0041998882520. The called party number does not match an entry in the mapping table, so it is not changed.
