Abstract:
A method for providing an internet call waitingâ€”voice over internet protocol service that facilitates simultaneous voice communication and internet access on a single telephone line comprising the steps of:(a) receiving at a service switching point an incoming telephone call to a subscriber connected to an internet, triggering a first query from the service switching point to a service control point, and forwarding bridging information from the service control point to a service node; (b) initiating an internet protocol call from the subscriber through a gateway to the service switching point and triggering a second query to the service control point, the second query prompting the service control point to send call routing information to the service switching point; (c) forwarding the internet protocol call from the service switching point to the service node based on the call routing information; (d) forwarding the incoming telephone call from the service switching point to the service node; (e) bridging the internet protocol call to the incoming telephone call with the service node using the call routing information and the bridging information; (f) maintaining the internet protocol call and the incoming telephone call on the service node; and (g) controlling further disposition of the internet protocol call and the incoming telephone call by communication between the service control point and the service node.
