3.1.13. gc_Listen( )

The gc_Listen( ) function can be uses to have an IP Media device listen to another device (for example, a dtiBxTx device).

To compel an IP Media device to listen to another device, the format is:

gc_Listen(linedev, sctsinfop, EV_SYNC)

where,

• linedev is the Global Call line device handle for an IP device (that is, the handle returned by gc_OpenEx( ) for a device with :N_iptBxTy in the devicename parameter).
• sctsinfop is a pointer to the transmit time slot information of the device to listen to. For a dtiBxTy device, this can be obtained by using gc_GetXmitSlot( ) on a Global Call line device that has :N_dtiBxTy in the devicename parameter.
• EV_SYNC indicates synchronous mode.

See Section 4.6, "Call Routing" for related information.
