4.5. Setting Coder Information

In System Release 5.x, coder information could be specified in the config.val file. In System Release 6.0, coder information can only be set at run time using the Global Call API. Coder information can be set:

• On a system-wide basis using gc_SetConfigData( )
• On a per line device basis using gc_SetUserInfo( )
• On a per call device using gc_MakeCall( )

Any coder information that is set using gc_SetUserInfo( ) overrides coder information set using gc_SetConfigData( ) and in turn any coder information set using gc_MakeCall( ) overrides coder information set using gc_SetUserInfo( ). The coder information is specified in a GC_PARM_BLK associated with the respective function. The set ID is GCSET_CHAN_CAPABILITY and the parameter ID is IPPARM_LOCAL_CAPABILITY which is a structure of type IP_CAPABILITY that contains the coder details.

See the Global Call IP Technology User's Guide for information on the supported coders and how to set them.
