Processing Mode Description and Example
REPLACE Other use of REPLACE is to replace the specific number based on other
number associated with the call. For example, replaceing the calling
number according to the called number.
Examples:
FXS 12345 REPLACE CPN-1/8621
FXS CPN13 REPLACE CDPN0/0
For calls from FXS ports with called party number of 1234, removing one
digit at the rear of the calling number and add 8621; for call s from FXS
ports with calling party number starting with 13, add 0 in front of the called
number.
END or ROUTE End of number transformation. From top to bottom, number transformation
will be stopped when END or ROUTE is encountered; the gateways will
route the call to the default routing after meeting EDN, or route the call to
the designed routing after meeting ROUTE.
Example 1:
FXS 12345 ADD -8001
FXS 12345 REMOVE 4
FXS 12345 END
Add suffix 8001 to the called number starting with 12345 for calls from
FXS ports, then remove four digits in front of the number to end number
transformation.
Example 2:
IP[222.34.55.1] CPNX. REPLACE 2680000
IP[222.34.55.1] CPNX. ROUTE FXS 2
For calls from IP address 222.34.55.1, calling party number is replaced by
2680000, and then the call is routed to FXS port 2 with the new calling
party number.
CODEC Designate the use of codec, such as PCMU/20/16, where PCMU denotes
G.711, /20 denotes RTP package interval of 20 milliseconds, and /16
denotes echo cancellation with 16 milliseconds window. PCMU/20/0
should be used if echo cancellation is not required to activate.
Example:
IP 6120 CODEC PCMU/20/16
PCMU/20/16 codec will be applied to calls from IP with called party
number starting with 6120.
RELAY Insert prefix of called party number when calling out. The inserted prefix
number follows behind REPLAY.
Example:
IP 010 RELAY 17909
For calls from IP with called party number starting with 010, digit stream
17909 will be outpulsed before the original called party number being
sending out.
Table 2-11 Routing Destination
Destination Description and Example

Example:
IP CPN[1,3-5] ROUTE NONE
