2.4.2.12 Call Park

Two forms of call parking are provided: directed call park and non-directed call park. In directed call park, the application specifies the destination address where the call is to be parked. This roughly behaves like a call transfer to the destination address, but it doesn't alert or time out as a transfer would.

In non-directed call park, the switch returns to the TAPI DLL the address where it parked the call. In either case, the function TSPI_linePark is used to park a call.

A parked call can later be retrieved. The TAPI DLL specifies the park address to TSPI_lineUnpark which returns an call handle to the unparked call. Appropriate LINE_CALLSTATE messages will be sent to the TAPI DLL as the call is reconnected.

TSPI_linePark

Parks a given call at another address.

TSPI_lineUnpark

Retrieves a parked call.
