Calls in the UK are generally controlled by the calling party, it is they who can clear the call. To avoid a Called Sub Held (CSH) condition where the called party clears, but the caller doesn't, such a call was force released after six minutes. This timer has been drastically reduced to prevent fraud.

Calls to operators are under the control of the operator and until the operator clears you won't get away. Originally called "manual hold".
