Abstract

A process and apparatus to facilitate communication between callers and callees in a system comprising a plurality of nodes with which callers and callees are associated is disclosed. In response to initiation of a call by a calling subscriber, a caller identifier and a callee identifier are received. Call classification criteria associated with the caller identifier are used to classify the call as a public network call or a private network call. A routing message identifying an address, on the private network, associated with the callee is produced when the call is classified as a private network call and a routing message identifying a gateway to the public network is produced when the call is classified as a public network call.

Claims

1. A process for operating a call routing controller to facilitate communication between callers and callees in a system comprising a plurality of nodes with which callers and callees are associated, the process comprising:

in response to initiation of a call by a calling subscriber, receiving a caller identifier and a callee identifier;

using call classification criteria associated with the caller identifier to classify the call as a public network call or a private network call;

producing a routing message identifying an address, on the private network, associated with the callee when the call is classified as a private network call; and

producing a routing message identifying a gateway to the public network when the call is classified as a public network call.

2. The process of claim 1 further comprising receiving a request to establish a call, from a call controller in communication with a caller identified by said callee identifier.

3. The process of claim 1 wherein using said call classification criteria comprises searching a database to locate a record identifying calling attributes associated with a caller identified by said caller identifier.

4. The process of claim 3 wherein locating a record comprises locating a caller dialing profile comprising a username associated with said caller, a domain associated with said caller, and at least one calling attribute.

5. The process of claim 4 wherein using said call classification criteria comprises comparing calling attributes associated with said caller dialing profile with aspects of said callee identifier.

6. The process of claim 4 wherein comparing comprises determining whether said callee identifier includes a portion that matches an IDD associated with said caller dialing profile.

7. The process of claim 4 wherein comparing comprises determining whether said callee identifier includes a portion that matches an NDD associated with said caller dialing profile.

8. The process of claim 4 wherein comparing comprises determining whether said callee identifier includes a portion that matches an area code associated with said caller dialing profile.

9. The process of claim 4 wherein comparing comprises determining whether said callee identifier has a length within a range specified in said caller dialing profile.

10. The process of claim 4 further comprising formatting said callee identifier into a pre-defined digit format to produce a re-formatted callee identifier.

11. The process of claim 10 wherein formatting comprises removing an international dialing digit from said callee identifier, when said callee identifier begins with a digit matching an international dialing digit specified by said caller dialing profile associated with said caller.

12. The process of claim 10 wherein formatting comprises removing a national dialing digit from said callee identifier and prepending a caller country code to said callee identifier when said callee identifier begins with a national dialing digit.

13. The process of claim 10 wherein formatting comprises prepending a caller country code to said callee identifier when said callee identifier begins with digits identifying an area code specified by said caller dialing profile.

14. The process of claim 10 wherein formatting comprises prepending a caller country code and area code to said callee identifier when said callee identifier has a length that matches a caller dialing number format specified by said caller dialing profile and only one area code is specified as being associated with said caller in said caller dialing profile.

15. The process of claim 10 further comprising classifying said call as a private network call when said re-formatted callee identifier identifies a subscriber to the private network.

16. The process of claim 10 further comprising determining whether said callee identifier complies with a pre-defined username format and if so classifying the call as a private network call.

17. The process of claim 10 further comprising causing a database of records to be searched to locate a direct in dial (DID) bank table record associating a public telephone number with said reformatted callee identifier and if said DID bank table record is found classifying the call as a private network call and if a DID bank table record is not found classifying the call as a public network call.

18. The process of claim 17 wherein producing said routing message identifying a node on the private network comprises setting a callee identifier in response to a username associated with said DID bank table record.

19. The process of claim 18 wherein producing said routing message comprises determining whether a node associated with the reformatted callee identifier is the same as a node associated the caller identifier.

20. The process of claim 19 wherein determining whether a node associated with the reformatted callee identifier is the same as a node associated the caller identifier comprises determining whether a prefix of said re-formatted callee identifier matches a corresponding prefix of a username associated with said caller dialing profile.
