gc_LoadDxParm( ) — set voice parameters associated with a line device The following is an example of a voice channel parameter (.dxp) file called dxchan.dxp (file names are defined by the user): # # D/xxx parameter file for downloading channel level # parameters supported by dx_setparm() and DX_CAP structure. # # Values are in decimal unless a leading 0x is included in which # case the value is hexadecimal. # # Refer to the Voice Software Reference for the DX_CAP # structure ca_* parameters. The upper case parameters can also # be found in the Voice Software Reference – Features Guide under the # dx_setparm() function. # # To set a parameter, uncomment (delete the '#' or ';') and set a # value to the right of the parameter name. # # ca_stdely # ca_cnosig # ca_lcdly # ca_lcdly1 # ca_hedge # ca_cnosil # ca_logltch # # Values of bitmask flags for setting ca_intflg # add desired flags to set ca_intflg # # DX_OPTEN = 1 # DX_OPTDIS = 2 # DX_OPTNOCON = 3 # DX_PVDENABLE = 4 # DX_PVDOPTEN = 5 # DX_PVDOPTNOCON = 6 # DX_PAMDENABLE = 7 # DX_PAMDOPTEN = 8 ca_intflg 5 # # # # ca_lowerfrq # ca_upperfrq # ca_timefrq # ca_maxansr # ca_ansrdgl # ca_mxtimefrq # ca_lower2frq # ca_upper2frq # ca_time2frq # ca_mxtime2frq # ca_lower3frq # ca_upper3frq # ca_time3frq # ca_mxtime3frq # ca_dtn_pres # ca_dtn_npres # ca_dtn_deboff # ca_pamd_failtime 224 Dialogic ® Global Call API Library Reference — January 2008 Dialogic Corporation
# ca_pamd_minring # ca_pamd_spdval # ca_pamd_qtemp # ca_noanswer # ca_maxintering set voice parameters associated with a line device — gc_LoadDxParm( ) A voice parameter file contains parameter definition lines and may contain comment lines. Each parameter definition line comprises a case-sensitive voice parameter as the first field of the line, a space, and a second field defining the parameter value. A comment line begins with either of the following characters: # character ; character The gc_LoadDxParm( ) function will return upon the first detected error. The reason for the error will be stored in the msgbufferp location. Typical error reasons are: a parsing error (in the .dxp file) a low-level function call error an open file failure error Note: Not all errors can be detected by the gc_LoadDxParm( ) function. Errors in the value of the voice call analysis parameters in the DX_CAP structure cannot be detected until a call is set up by the gc_MakeCall( ) function. All channel-level parameters set by the voice function, dx_setparm( ), can be set using the gc_LoadDxParm( ) function. Global Call uses the dx_setparm( ) parameter names to identify all voice channel-level parameters: DXCH_DFLAGS DXCH_DTINITSET DXCH_DTMFDEB DXCH_DTMFTLK DXCH_MAXRWINK DXCH_MFMODE DXCH_MINRWINK DXCH_PLAYDRATE DXCH_RECRDRATE DXCH_RINGCNT (Not used. The default number of rings parameter in the .cdp file sets this parameter value.) DXCH_WINKDLY DXCH_WINKLEN Also see the Dialogic ® Voice API Library Reference for a description of these parameters. The gc_LoadDxParm( ) function supports all basic and enhanced call progress fields defined in the DX_CAP data structure. The parameter value may be entered as a decimal value or as a hexadecimal value when prefixed with a “0x”. The call analysis parameters defined in the DX_CAP data structure affect the gc_MakeCall( ) function. Global Call uses the DX_CAP data structure names to identify all call progress parameters: Dialogic ® Global Call API Library Reference — January 2008 225 Dialogic Corporation
