The procedure is as follows:

1. A request (GCEV_HOLDCALL event) to place a connected call on hold is received.
2. The application accepts the hold request and should unroute the SCbus time slot for the requested call.
3. The application accepts the hold request using the gc_HoldAck( ) function.
4. A request (GCEV_RETRIEVECALL event) to retrieve a held call is received.
5. The application receives the retrieve request and should reroute the SCbus time slot for the requested call.
6. The application rejects the hold request and takes no action on the call's SCbus time slot.
7. The application rejects the hold request using the gc_HoldRej( ) function.

Note: The retrieval of a held call cannot be rejected when using the DPNSS protocol.
