Abstract
A normalizing signaling gateway (NSG) routing node receives a first signaling message formatted according to a first variant of a common or standard signaling protocol, such as ISUP, and creates a second signaling message based on the first message. The second signaling message includes a normalized component and a variant component. The second signaling message may then be routed to a second NSG routing node or to a media gateway controller. Because the NSG routing node converts messages to and from variants of a standard signaling protocol, the media gateway controller is not required to support all of the variants of the standard signaling protocol, and its complexity is reduced.
