Abstract:
Say John on a PSTN needs to contact Chuck. Chuck's telephone is a SIP, H.323, DCP, or analog endpoint, connected to the PSTN via an enterprise network and gateway. John already knows Chuck's number. Before dialing Chuck's phone number, John navigates to a URL that includes something unique to Chuck in its name, such as www.xyzco.com/303-555-212 or www.xyzco.com/chuck. The webpage of the URL contains two fields: number you will be calling from and subject. John enters his number and then enters the subject “Sale going through!” John then dials Chuck's number. The enterprise network receives the call and the associated Caller-ID via its PSTN gateway, maps the inbound Caller-ID to the information provided by John, routes the call to Chuck's phone, and causes the display on Chuck's phone to show John's Caller-ID and the subject of the call. Chuck thinks the subject may be important and therefore decides to answer.
