Gateway can also serve as a central device to provide interaction of other VoIP devices (terminals and gateways). Thereto, gateway supports H.323-GateKeeper and SIP - Proxy protocols.
To ensure interaction with other VoIP- gateways, the gateway supports E.164 public networks numbering system.
Gateway can be controlled through RS-232 console. Control is terminated through Telnet.
