In one embodiment, a signaling message is received from an endpoint. It is determined from the signaling message whether, prior to sending the signaling message, the endpoint performed network address translation on the body of the signaling message. If it is determined from the signaling message that, prior to sending the signaling message, the endpoint did not perform network address translation on the body of the signaling message, application layer gateway functionality is applied to the body of the signaling message such that a modified signaling message is generated.
