Table 1 summarizes the types of information elements that can be specified, the corresponding set 
IDs and parameter IDs used to set the information, the functions that can be used to set the 
information, and an indication of whether the information is supported when using H.323, SIP, or 
both. For more information on the various parameters, refer to the corresponding parameter set 
reference section in 

.

Bearer Capability IE

• IPPARM_BEARERCAP

gc_SetUserInfo( )

only

Call ID (GUID)

• IPPARM_CALLID

Note: Setting the Call ID must be done 

judiciously because it might affect the call 
control implementation supported by the 
stack. The Call ID should be treated as a 
GUID and should be unique at all times.

† If no transmit or receive coder type is specified, any supported coder type is accepted. The default is “don’t care”; that is, any 
media coder supported by the platform is valid.
†† The duration parameter can be set to GC_SINGLECALL (to apply on a call basis) or to GC_ALLCALLS (to apply on a line 
device basis). 
††† On the terminating side, can only be set using gc_SetConfigData( ) on a board device. See
