Abstract
A system and method for performing messaging between telephones in a data network telephone system. The message communications may be managed by a messaging application connected to the data network. The messaging application detects when a telephone is connected to another telephone and sends a messaging input screen to the first telephone. The messaging application may determine the availability of other users for messaging and may control messages communicated between the first telephone and the other users. The messages may be text or voice messages.
