Abstract
Methods and devices for managing traffic at a session border controller (SBC) are described. A signal portion of traffic en route from a source in a virtual private network (VPN) to a destination is received. The signal portion has embedded therein an identifier that uniquely identifies the VPN. The identifier is accessed to determine whether the destination is also in the VPN. A decision whether to direct a media portion of the traffic to an SBC is made depending on whether or not the destination is outside of the VPN.
