4. Dialing Principles
The VoIP Router provides the registration for multiple VoIP Service Providers, and each VSP has a private digit
map. Hence, the routing and number translation may vary. We use two part, Routing and Number Translation,
to explain the dialing principle of the VoIP Router.
Dialing Options
1.
Dial the phone number which you want to call and press # to call out immediately. Note that if the “#
(pound)” not dialed, the number will be called out after 4 seconds by default. The period between
number dialed and call out is named “Inter Digits Timeout”. (Configurable from “DTMF”, default=4
seconds, see page 55).
2.
If the phone number matches a rule of Digit Map Table, the phone number will be routed the assigned
VSP or Phone Book according VoIP Route Profile automatically.
Number Translation
Phone number is dialed by user. The system will check if the phone number is matched Digit Map Table. If no
matched is found from Digit Map Table, it will use the phone number to look up private digit map of the server
set in VoIP Routing Profile. The system will translate the phone number to global number used to look up
private digit map of the server set in VoIP Routing Profile.
