Call parking enables a call to be placed in a call parking lot with an assigned number. This parked call can be picked up by any user with any phone.

The caller who is placed in the call parking lot will have on-hold music played to them while they are awaiting a pick-up. Calls are assigned specific parking lot numbers upon transfer. The parking lot number is essential to this system, so it is imperative that the person transferring the call notes which parking lot number the call is placed in - the number is read to the transferring user after dialling the extension for the parking lot. Calls can be answered simply by dialling the parking lot number.

This system is extremely useful when there are phones located where there may be more than 1 user (e.g. factory floor, newsroom, meeting room, etc.). Calls can be placed in a parking lot, and the receptionist can simply contact the intended recipient and tell them the code to access the call (e.g. "Rob your wife is on line 76" - Rob simply dials 76 on any phone and is connected to his wife).
