Figure 54. Call passing an input and an output mapping table

Let’s assume we manipulate an incoming ISDN call using the PRIV-TO-GLOB mapping table as in the previ- ous example. Figure 54 shows this situation again. Let’s further assume the call router routes back the call to the interface IF-PHONES. In that case, the output mapping table used on this interface is applied to all call parameters. The calling and called party number is transformed form the global to the private numbering plan before the call is offered to the remote ISDN terminal.

Note For interface mapping you can use only mapping tables that examine general call parameters. For example, you cannot use a called-e164 to called-e164 mapping table, use a e164 to e164 mapping table instead.

Configuring the precall service tables

Precall service mapping tables are used to convert dialed special numbers like *61 to invocation commands for supplementary services like call-waiting, etc. Precall service tables are configured as part of the call router in the context CS configuration mode. Precall service tables are used on an FXS interface where the attached phone should be able to activate or deactivate services by dialing a special number. SmartWare currently supports the following service commands:

•activate-cw—Activates call-waiting on the interface that uses the precall service table. Once activated a sec- ond incoming call is possible on the interface. The second call is announced to the first call. The user can then decide whether to accept or reject the new call.

•deactivate-cw—Deactivates call-waiting on the interface that uses the precall service table.
