Node reputation based on knowledge of PSTN calls
First Claim
1. A system comprising:
- a memory; and
a processor in communication with the memory, the memory including computer code executable with the processor, wherein the computer code is configured to;
provide trust relationship information for a telephone number, the trust relationship information indicative of whether at least one node considers a target node as including or as being associated with a Voice-over-Internet-Protocol (VoIP) call agent for the telephone number based on a determination, at the at least one node, that at least one public switched telephone network (PSTN) call to the telephone number arrived at the VoIP call agent, the determination made in response to receipt, from the target node, of demonstrated knowledge of at least one attribute of the at least one PSTN call that demonstrates knowledge of the PSTN call; and
determine a target trust relationship from a validating node to the target node based on the trust relationship information, wherein the target trust relationship indicates a level of trust the validating node has in the target node being associated with or including the VoIP call agent for the telephone number, wherein the validating node and the at least one node are in different respective administrative domains of a network.

Abstract
A system may provide trust relationship information for a telephone number, where the trust relationship information may indicate whether one or more nodes consider a target node as including or as being associated with a VoIP call agent for the telephone number based on demonstrated knowledge of a PSTN call. The system may determine a target trust relationship to the target node based on the trust relationship information, where the target trust relationship indicates a level of trust a validating node has in the target node being associated with or including the VoIP call agent for the telephone number, and where validating node and the one or more nodes may be in different respective administrative domains of a network.

8. Logic encoded in one or more tangible non-transitory media for execution with a processor and when executed operable to:
-
generate trust relationship information for a telephone number, the trust relationship information including an indication that at least one node considers a target node as including or as being associated with a Voice-over-Internet-Protocol (VoIP) call agent for the telephone number based on a determination, at the at least one node, that at least one public switched telephone network (PSTN) call to the telephone number arrived at the VoIP call agent, the determination made in response to receipt, from the target node, of demonstrated knowledge of at least one attribute of the at least one PSTN call that demonstrates knowledge of the PSTN call; and determine a target trust relationship to the target node from the trust relationship information, wherein the target trust relationship indicates a degree to which a validating node trusts the target node as being associated with or including the VoIP call agent for the telephone number, and the validating node and the at least one node are in separate administrative domains. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method comprising:
-
providing at least a portion of trust relationship information for a telephone number, the trust relationship information indicating that at least one node considers a target node as including or as being associated with a Voice-over-Internet Protocol (VoIP) call agent for the telephone number based on a determination, at the at least one node, that at least one public switched telephone network (PSTN) call to the telephone number arrived at the VoIP call agent, the determination made in response to receipt, from the target node, of demonstrated knowledge of at least one attribute of the at least one PSTN call that demonstrates knowledge of the PSTN call; and validating an identity of the target node for the telephone number based on a target trust relationship, the target trust relationship determined from the at least a portion of the trust relationship information, the target trust relationship indicating a level of trust that a validating node has in the target node being associated with or including the VoIP call agent for the telephone number, the validating node and the at least one node being in a first administrative domain and a second administrative domain, respectively. - View Dependent Claims (15, 16, 17, 18, 19, 20)
