Abstract
A method, performed in a network element, for communicating packet multimedia data between a first endpoint and a second endpoint, the method comprising the machine-implemented steps of receiving an outbound multimedia data packet; determining if the outbound multimedia data packet originated from a first endpoint that is logically behind a security device; determining and storing information identifying a logical pinhole in the security device, wherein the logical pinhole is associated with expected inbound multimedia data packets directed to the first endpoint; performing an action that keeps the logical pinhole open during all of a communication session between the first endpoint and the second endpoint; and forwarding inbound multimedia data packets directed from the second endpoint to the first endpoint via the logical pinhole.
