4.17. gc_SetBilling( )

On DM3 boards, the gc_SetBilling( ) function is not supported for E-1/T-1.

On Springware boards, the gc_SetBilling( ) function sets different billing rates on a per call basis. For example:

• To charge the call, use gc_SetBilling(crn, GCR_CHARGE, NULL, EV_SYNC)
• To select no-charge for the call, use gc_SetBilling(crn, GCR_NOCHARGE, NULL, EV_SYNC)

The gc_SetBilling( ) function is called after the GCEV_OFFERED event arrives and before issuing a gc_AcceptCall( ) or gc_AnswerCall( ) function.

Not all protocols support this feature; see the Global Call Country Dependent Parameters (CDP) Reference for protocol specific limitations.

The mode parameter must be set to EV_SYNC. Asynchronous mode (EV_ASYNC) is not supported for this function.
