2.3.2. Requesting Additional DNIS Digits

The gc_CallAck( ) function can be used to request additional DNIS information from the network. The type field in the GC_CALLACK_BLK in this context is GCACK_SERVICE_INFO.

Note: The GCACK_SERVICE_INFO define deprecates the GCACK_SERVICE_DNIS define used in previous releases.

When the digits are collected, the gc_CallAck( ) function completes. These digits may be retrieved using the gc_GetCallInfo( ) function with the info_id parameter set to DESTINATION_ADDRESS.

The following example shows how to request one additional destination address (DNIS) digit:

    GC_CALLACK_BLK callack; 
    callack.type = GCACK_SERVICE_INFO; 
    callack.service.info.info_type = DESTINATION_ADDRESS; 
    callack.service.info.info_len = 1;   /* One additional digit */ 

Note: When using DM3 boards, the only info.info_type value supported is DESTINATION_ADDRESS.

When a GCEV_MOREINFO event is received as a termination event to gc_CallAck( ), the result value for the event will indicate if more digits can be retrieved. See the Global Call API Library Reference for more information.
