Default message playback speed. For 4.2(1) and later, this allows you to configure the default speed up/slow down value for message playback.
Subscriber Conversation Style. For Unity 4.0(3) and later systems you can choose from different conversation styles, for versions of Unity prior to that only the standard Unity conversation is allowed.
Limit List. Added in Unity 5.0(1). This button brings up a form that lets administrators decide which subscriber conversation styles can be selected by users through the PCA web interface.
Time Format. Allows timestamps to be presented in 12 hour or 24 hour clock formats.
Announce sender information. Select “true” from this drop down list to have Unity say the name of the subscriber that sent the message (if known) or announce the caller’s ANI information (if known and enabled) when users are listening to messages over the phone. If this is set to false then no sender information is played regardless of if it's from a subscriber or an outside caller.
Announce timestamp. You can select “before message” or “after message” in this drop down to dictate if the timestamps are played before subscribers hear the message or after when they are listening to messages over the phone.
Volume levl. You can select “quieter”, “medium” and “Louder”. Medium is the default and means messages playback at normal volume (i.e. no change). Quieter means they play back about %25 quieter than normal and louder means they play about %25 louder than normal.
Announce senders extension for messages from subscribers. For Unity 4.0(3) and later, setting this option will result in the primary extension number of the subscriber who left the message being played along with their voice name (if recorded) when identifying the sender of a subscriber to subscriber message. Note that to hear sender information, including extensions for subscribers, users must have the "Announce sender information" option enabled.
Announce ANI for messages from unidentified callers. For Unity 4.0(3) and later, this option will have Unity include the Automatic Number Identification (ANI) string (if provided) when identifying the source of a message left by an unidentified caller. For this option to be useful the switch integration must provide ANI information for calls into the voice mail server. Note that to hear sender information, including ANI for outside callers, users must have the "Announce sender information" option enabled.
Say message number. Select “true” from this drop down list to have Unity announce the sequential number of a message ("Message one is...") when users are listening to messages over the phone. This can be used with the "Announce total number of new messages" check box to help subscribers keep track of the number of unheard messages as they go through the list.
Message review skip ahead/back tim (milliseconds). This dictates the amount of time that the jump ahead/back keys will move the message during playback. By default this is 5000 ms (5 seconds). This option is only available with Unity 4.3(1) and later.
