Configuration and Application
Examples
This Chapter provides some examples of VoIP Gateway configuration and
application.
Configuration
The VoIP Gateway can be configured to register to a SIP server and make calls through the
server. In SIP server environment, the SIP server handles the registration and serves as a
proxy server for call signal. The VoIP Gateway may be configured to work in Direct
Inward Dial (DID) mode or regular mode. In DID mode, calls originated from FXO ports
are routed to SIP server for termination directly. In regular dialing mode, when an incoming
call is detected from FXO port, the VoIP Gateway plays dial tone and waits for the final
destination number to be dialed. See Line Settings Screen for further details of DID mode
configuration.
