A mechanism is disclosed for facilitating the performance of communication services in a communication network. An enhanced proxy server receives a signaling message and proxies the message to an application server. Further, the enhanced proxy server responds to the message by extracting a set of data from a data store and making the set of data available for use by the application server in responding to the signaling message. Similarly, a registration server may receive a signaling message from a communicating entity and may responsively make data available for use by an application server in responding to signaling messages regarding the communicating entity.
