4.20.  gc_SetParm( )

The gc_SetParm( ) function sets the default parameters and all channel information associated with the specific line device. In addition to the GCPR_CALLINGPARTY parameter, which is common across all technologies and documented in the Global Call API Library Reference, the parameters listed in Table 10 are supported.

Table 10.  Parameters Supported, gc_GetParm( ) and gc_SetParm( )

Parameter	Level	Description	Supported on
GCPR_CALLPROGRESS	channel	Enables or disables call progress; enabled by default. If this parameter is disabled, post-connect call progress is also disabled, regardless of the setting of GCPR_MEDIADETECT.	DM3, Springware
GCPR_LOADTONES	channel	Enables or disables downloading of predefined call progress tones to the firmware. These tones are predefined in the E-1 CAS or T-1 robbed bit specific configuration files and are used for call progress.	Springware
GCPR_MEDIADETECT	channel	Enables or disables post-connect call progress or media detection; disabled by default.	DM3
GCPR_MINDIGITS	channel	Specifies the minimum number of digits to receive before a call is offered to the application.	DM3

For further information about the use of the GCPR_LOADTONES parameter, see Section 3.1.  Global Tone Detection (GTD) Tone Considerations. The tones are downloaded during execution of the gc_Attach( ) or gc_AttachResource( ) function.

For further information about the use of the GCPR_CALLPROGRESS and GCPR_MEDIADETECT parameters, see Section 3.2.  Call Progress and Call Analysis.
