Abstract

A method and apparatus for enabling customer premise Public Branch eXchange (PBX) service feature processing to be performed in a service provider network using an intermediary device are disclosed. For example, the method receives a signaling message by an intermediary device managed by a service provider of a communication network, where the signaling message requires processing by a customer premise Public Branch eXchange (PBX), wherein the signaling message is in accordance with a network signaling format. The method interworks the signaling message into a signaling message in accordance with a PBX signaling format, and sends the interworked signaling message to the customer premise PBX to retrieve service logic and data associated with the signaling message.
