Method and apparatus for enabling customer premise public branch exchange service feature processing

A tangible computer-readable medium storing instructions which, when executed by a processor of an intermediary device, cause the processor to perform operations for processing a signaling message, the operations comprising:

• receiving a signaling message by the intermediary device managed by a service provider of a communication network, where the signaling message requires processing by a customer premises public branch exchange, wherein the signaling message is in accordance with a network signaling format;
• interworking the signaling message into an interworked signaling message in accordance with a public branch exchange signaling format;
• and
• sending the interworked signaling message to the customer premises public branch exchange to retrieve service logic and data associated with the signaling message, wherein the service logic and data are associated with a service that is to be provided by the communication network without a bearer path being established to the customer premises public branch exchange.
