A system and method of serving text-based data messages to a caller identification (caller ID) system in a telecommunications network environment may overwrite source-specific information in a selected data packet header field with text-based message data. A protocol translator may enable text data to be served to a caller ID system used in conjunction with a plain old telephone service (POTS) telephone as well as with a Session Initiation Protocol (SIP) device. Text messages addressed and routed to a caller ID enabled device may be displayed on the caller ID display.
