Patent ID: 8694658

Claim:
An apparatus, comprising: a policy element operable to receive a query for a policy that pertains to a selected one of first and second endpoints, wherein the first and second endpoints are two distinct entities, each endpoint being associated with a virtual private network (VPN), wherein the VPNs are disjointed, wherein interaction occurs between a session border controller (SBC) and a session initiation protocol (SIP) signaling entity, wherein each SBC makes a mapping between signaling entity information and pre-configured SBC VPN information, wherein credential negotiation occurs between the policy element and the SBC such that a selected policy within the policy element determines that a requested communication session is conducted between the endpoints, wherein the pre-configured SBC VPN information is used for dynamic policy configuration of the communication session, and wherein a local database is checked for a log of an existing call and for a prior configuration between the endpoints.
