The Unpark function retrieves the call parked at the address given in the DestAddress parameter. When the function succeds, the retreived call is returned as a ThbTapiCall object. If you're using ThbTapiLine in an asynchronous manner, the returned call will become valid, when the related TAPI reply message is received with a reply code equal to zero. The call will be originated at the address spezified by the AddressID paramter. Valid AddressID are 0 to ThbTapiLine.Addresses.Count-1.

Declaration

function Unpark(AddressID: DWORD; DestAddress: String): ThbTapiCall;
