Configuring Gateway to Gateway Signaling on I-SBC

The gateway-to-gateway signaling is a protocol that transports call signaling messages between the SBC (and the GSX) instances over a TCP connection and requires that an external PSX is part of the network. The SBC supports gateway-to-gateway signaling on all platforms, including virtualized SBC SWe deployments.
