Configuring the precall service tables 388

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.
