Configuring a Private Hold Key
Public hold allows any shared line to retrieve the held call. Private hold only allows the hold
party to retrieve the held call. For example, you can retrieve the held call on either phone A or
phone B when you place a call on public hold; you can retrieve the held call only on phone A
when you place a call on private hold on phone A. You need to configure a private hold key
before you place the call on private hold.
To configure a private hold key via phone user interface:
Tap Settings from the Home screen.
