4.2.10. gc_SetParm( )

The gc_SetParm( ) function can be used to configure the following line device parameters:

• GCPR_CALLINGPARTY - The default calling party address for the circuit. This parameter is overwritten by the one in the S7_MAKECALL_BLK if specified. Use the paddress field of the GC_PARM union.
• GCPR_MINDIGITS - The minimum number of digits to collect before reporting an OFFERED call. An overlap receive procedure is used in case the initial number of digits does not reach the minimum number set using this function. Use the intvalue field of the GC_PARM union.
• GCPR_RECEIVE_INFO_BUF - The size of the cyclic buffers used to store signaling messages that can be retrieved using the gc_GetSigInfo( ) function. See Section 4.2.5, gc_GetSigInfo( ) for details. Use the intvalue field of the GC_PARM union.
• GCPR_UNKNOWN_ISUP_MSGS - Enables the configuration of a line device to receive ISUP messages not recognized by the SS7 call control library. See Section 5.12, Sending and Receiving ISUP Messages for more information.
