Configuring private hold soft key or 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. By default, the
private hold soft key isn’t displayed on the LCD screen. You need to configure either the
private hold soft key or a private hold key before you place the call on private hold.
To configure the private hold soft key via web user interface:
1. Click on Settings->Softkey Layout.
2. Select Enabled from the pull-down list of Custom Softkey.
3. Select On Talk from the pull-down list of Call States.
