The procedure is as follows:

1. The application places a connected call on hold using the gc_HoldCall( ) function.
2. When the call is held, the application will receive a hold acknowledge (GCEV_HOLDACK) event.
3. The application should unroute the SCbus time slot for the held call.
4. The application retrieves a held call using the gc_RetrieveCall( ) function.
5. When the call is retrieved, the application will receive a retrieve acknowledge (GCEV_RETRIEVEACK) event.
6. The application should unroute the SCbus time slot for the retrieved call.
7. When a call is not held, the application will receive a hold reject (GCEV_HOLDREJ) event.
8. The application should take no action on the call's SCbus time slot.

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