AT&T MERLIN LEGEND Release 4.0 Feature Reference page 577

Feature Reference
For an MLX telephone, Voice Announce to Busy is automatically available
because the MLX extension jack provides two communication channels. For an
analog multiline telephone, enabling the feature requires assigning two
consecutive extension jacks to the telephone. The extension assigned to the
odd-numbered jack is the telephone's extension; the extension assigned to the
next higher even-numbered jack is used for voice announcements and cannot
be dialed. A single-line telephone cannot receive voice-announced calls even if
the set has a speakerphone.
When a caller makes a voice-announced call to an extension with Voice
Announce to Busy, the caller hears a tone. The called person hears a beep and
the caller's voice over the speakerphone, unless one of the following is true:
The called person is already using the speakerphone. In this case, the
caller hears ringback and the called person hears an abbreviated ring, if
programmed.
The called person has turned off Voice Announce to Busy. In this case,
the caller hears ringback and the called person hears ringing for an
inside call.
The called person has turned on Do Not Disturb. The caller hears a busy
signal and, if the caller has a display telephone, sees the message
QCC Voice Announce
In Release 4.0 and later releases, if QCC Voice Announce is Enabled, then the
fifth Call button on QCCs can be used to announce a call on another user's
speakerphone. If Voice Announce is Disabled (factory setting), then the fifth
Call button functions the same as any other Call button. This setting applies to
all QCCs in the system. Inspecting this button displays
Announce for QCCs is enabled, and
is not enabled.
QCCs cannot receive Voice Announce calls. Any call to a QCC from a Voice
Announce SA button from another extension is received at the QCC as a ringing
call.
Considerations and Constraints
By turning off Voice Announce to Busy, MLX and analog multiline telephone
users can prohibit all voice announcements to their telephones. When a user
turns off Voice Announce to Busy, the Hands Free Answer on Intercom (HFAI)
capability is also turned off.
Voice Announce to Busy should be turned off at data stations that include an
MLX telephone or that include an analog multiline telephone, a GPA, and a
modem.
