8.3.26.4 Associating and Disassociating a T.38 Fax Device with a Media
Device
To support T.38 fax server operation, the gc_SetUserInfo( ) function is used to associate a T.38
Fax device with a Media device to facilitate a switch from an audio session to a T.38 fax session.
Similarly, when switching form a T.38 fax session to an audio session, the gc_SetUserInfo( )
function is used to disassociate the T.38 Fax device from the Media device. The relevant function
parameter values in this context are:
target_type
GCTGT_GCLIB_CRN
target_id
CRN
duration
GC_SINGLECALL

– IPPARM_T38_DISCONNECT when switching from T.38 fax to audio
• an associated IP_CONNECT structure that contains the fax and media handles and the
connection type (half-duplex or full-duplex)
