Call Park Extensions (also known as BLF Call Park) is an 8x8 phone system feature that allows users to park and retrieve calls by pressing a Busy Lamp Field (BLF) key on their Polycom IP Phone. This feature requires Power Keys. Benefits include:
- Allowing faster call routing through call parking.
- Parking and retrieving calls at the touch of a button without the need to remember a call parking extension number.
Note: Call Park extensions are added in order: 195000 through 199999. The existing call park range is 491, 492, 493, through 699, but no new extensions are created in that range. Extensions 500, 551 through 559, are reserved for use with other services.
