In one embodiment, a network device determines one or more conditions for invoking one or more real applications to the network device for a session. This determination may be made at the initiation of the session, such as when a SIP INVITE message is received. The one or more conditions allow real applications to be invoked when a future event satisfies the condition. When it is determined that a condition is satisfied, a real application associated with the condition is then invoked. Accordingly, conditions may be set for real applications that may be tested against future events that have not yet occurred. This allows deferred invocation of real applications. Accordingly, if real applications are not needed for a session, then they are not invoked. But, when a real application is needed, it can be invoked.

Deferred invocation of communication services

A system and method for applying a communication feature extension includes facilitating an exchange of requests between an originating endpoint and a terminating endpoint using a first identifier associated with the originating endpoint and a second identifier associated with the terminating endpoint. A modified request is received during the exchange. The modified request includes a new identifier representing a selected one of a modified first identifier and a modified second identifier, and an extension providing information about handling the modified request. The extension included in the modified request is determined and applied.
