SEND183
, meaning to force sending 183. For example,
FXS CPN3
SEND183,
meaning for CPN from the FXS that starts with 3, send 183.
CODEC
means the encoding and decoding method of the CPN/CDN, followed by the actual
name of the codec. For example
PCMU/20/16.
PCMU is the codec method; 20 meaning every 20ms; 16 is the length of echo cancellation. If
echo cancellation is not enabled, a 0 will append at the end automatically (like PCMU/20/0),
indicating echo cancellation is disabled. For example,
IP 6120
CODEC
PCMU/20/16
This means for CDN from an IP address and starting with 6120, use codec PCMU/20. Echo
cancellation length is 16ms.
RELAY
is one function of IP dialing. For example,
IP 010
RELAY 17909
This means for CDN from an IP address and starting with 010, dial 17909 first.
Route Exchange
One route consists of five sections: Origination, Number, Action, Destination, and Destination
Information. Routing table routes the number from an origination to the destination.
․
Origination
can have the following values: IP, FXS, and FXO. IP can be any IP address, a
specified IP address, and a specified IP address plus the port number. FXS and FXO can be a
specific line number (for example FXS1, FXO2 or FXS 1 – 2, etc.)
․
Number
can be the calling number, or the called number. Default is the called number. If it is the
calling number, add CPN before the number as the identifier. The number can use any digit
between 1 to 9, *, ., #, X etc, just like the digit map. The common rules are:
Numbers, such as 114, 61202700
The beginning digits of a number, such as 61xxxx, or 612x, or 61
Expressions such as 268[0-1, 3-9], which indicates a number that starts with 268 and
followed by any number from 0 to 1 or 3 to 9
The search for a matching number follows the principle of “shortest and quickest”. For
example, x equals all numbers; xx equals all two-digit numbers; 12x equals all three-digit
numbers that start with 12
․
Action
should be ROUTE, meaning to route a call.
․
Destination
can have the following values: NONE, IP, FXS, and FXO.
Routes that have IP as the Origination usually have FXO, FXS, or NONE as Destination
Routes that have FXO or FXS as the Origination usually have IP or NONE as Destination
