<p>A presence registration and routing node (500) includes an advanced database communications module (ADCM) for receiving queries for presence information. The ADCM module forwards the queries to a presence application, such as a SIP, IMPP, or presence application. The presence application formulates a presence-server compatible message, forwards the presence-server-compatible message to a presence database (516), receives a response from the database, and forwards the response to the ADCM module to be sent to the requestor over an IP network. The presence database (516) may be internal or external to the presence registration and routing node (500).</p> |
