What is call parking ?
Call parking is an interesting feature available in modern EPABX, also known as PBX(Private Branch Exchange), which allows a person to put an active call on hold and then retrieve the same call from another telephone number or extension.
Normally, this is activated by any of the parties, either calling party or called party, by pressing some special button/key available on the telephone instrument or few sequence of keys. After a call is parked, the parked, it can be retrieved or it can be again activated by dialing parked number from any other telephone extension in the same PBX.
Example of how Call PArk feature in PBX is used :-
1. PBX extension 111 calls PBX extension 222.
2. Extension 222 picks the call, dials 7n where n is any digit used for “parking” the call. Extension 111 hears a “call hold” tone.
3. Now, another extension 333 can dial 77n and “pick the call”, it means extension 333 and extension 111 will be now connected.
Many PBX sends back the call to the original extension who has put the call on “PARK” by calling the extension again if the “parked call” is not again picked or activated by some extension again. In the above example, if extension 333 does not pick the call after certain time, 222 will ring again and it will be connected to extension 111.
The procedure for using “Call Parking” feature may vary from one PBX manufacturer to another. But the basic principle remains the same, only the key press sequence may vary.
Almost all modern PBX systems come with this feature. It is useful when a person needs to move from one place to another during a call in a office premise. In that case, instead of asking the caller to call again, on may put the call on parking and then pick up from the location and continue the conversation.
In hotel PBX, it can be a useful feature where front desk may park calls from guest rooms and then ask restaurant or other departments to pick the call. It works better than plain old call transfer, as it can ensure the call continuance. In simple call transfer, the transferred number may be busy or not at the desk.
