The Posted Messages feature is available with Communication Manager Release 1.3 (V11) or later.

A user activates the Posted Messages feature to post a message to his or her telephone. When a person calls that user, the telephone display of the caller shows the posted message for 4 seconds. During those 4 seconds, the telephone of the caller does not display an incoming call alert. After 4 seconds, the telephone display of the caller reverts back to the normal called number and called name.

To use the Posted Messages feature, the telephone of the caller must be able to display messages. Only internal callers can post or view a posted message. Callers from outside your system cannot view a posted message.
