H.323 Configuration
IPX-1500 supports the “H.323” VoIP standard. There are two modes of operation: P2P mode and GK
mode.
The IP mode allows for direct communication and is used when both parties have static IP
address.
The GK mode is used when at lease one party has dynamic IP address. The Gatekeeper acts like
an address-translating middleman. Every time connects to the Internet; the PC will automatically
register with the Gatekeeper to let it know about current IP address. You can then communicate
with other members of the same Gatekeeper service.
