Abstract

According to the preferred embodiments of the present invention, a method and an apparatus for efficiently and accurately processing incoming connection establishment requests is disclosed. The present invention allows the signaling provider of the network interface software to determine ownership of an incoming request by accessing client-provided information in the form of call filters. Upon receiving an incoming call establishment request, the network interface software matches the request to information previously provided by the clients of the network interface software. The network interface software can thus determine the correct recipient, negotiate parameters on the owner'"'"'s behalf, establish a call connection, inform the client that the connection has been established, and inform the client of specific parameters relating to the incoming call.

a signaling provider residing in the memory, wherein the signaling provider uses at least one of the at least one call filter objects to determine ownership of at least one of the plurality of incoming call establishment requests, said call filter objects comprising information provided by said plurality of clients,

wherein the signaling provider uses at least one of the at least one of the plurality of call filter object to negotiate connection parameters with a computer that sent at least one of the plurality of incoming call establishment requests.

12. A method comprising the steps of:

receiving at least one incoming call establishment request;

using a signaling provider to determine ownership of the at least one incoming call establishment request, said ownership being determined for a client amongst a plurality of clients and based upon information supplied by said plurality of clients, and

using said information to negotiate connection parameters with a computer that sent the at least one incoming call establishment request.

13. The method of claim 12 wherein the step of using a signaling provider to determine ownership of the at least one incoming call establishment request comprises the step of using at least one call filter object to determine ownership of the at least one incoming call establishment request.

14. The method of claim 13 wherein the step of using at least one call filter object to determine ownership of the at least one incoming call establishment request comprises the step of using at least one selector object to determine ownership of the at least one incoming call establishment request.

15. The method of claim 12 wherein the step of using a signaling provider to determine ownership of the at least one incoming call establishment request comprises the step of using a plurality of call filter objects to determine ownership of the at least one incoming call establishment request.

16. The method of claim 15 wherein the step of using the plurality of call filter objects to determine ownership of the at least one incoming call establishment request comprises the step of using a plurality of selector objects to determine ownership of the at least one incoming call establishment request.

17. The apparatus of claim 15 wherein the step of using the plurality of call filter objects to determine ownership of the at least one incoming call establishment request comprises the step of using a plurality of selector to determine ownership of the at least one incoming call establishment request.
