From an active call i.e. talk state, the user enters consultation state, receives dial tone and keys the feature access code. User then dials the directory number of the desired location to which the call will be parked;

From an active call i.e. talk state, the user enters consultation state, receives dial tone and keys the feature code for self-park. The call is parked and the user hears positive acknowledgement tone and is free to make further calls;

OR

User hears negative acknowledgement tone and the user can now return to the calling party or can re-try the feature (e.g. attempt to park to a different extension); or the user can use another feature.

Once parked, user receives 'holding' tone as appropriate to the system. User can now only wait for re-connection or hang up.

If the parked to user is idle when the call is parked, then the user will be given no indication (the requirement is that the call is parked without ringing the terminal). However, whilst the park-timer is running the user will be given special dial tone if they go off-hook. After the park-timer expires then the terminal will be alerted if idle, or when they becomes idle.

The parked to user cannot receive further incoming calls, but can make outgoing calls.

If the parked to user is busy when the call is parked, then the user will be given audible notification in the form of camp-on tone.

In the case of parking to a busy user, the call is transferred into camp-on and is then treated as a normal camp-on call.
