2.6.3 Examples of Routing Rules
This section provides examples of how a routing table can be used to implement features.
1)
Assigning One Phone with Dual Numbers
2)
Hunt Group
3)
Outbound Call Barring
4)
Trunk Group for Outbound Calling
Assigning One Phone with Dual Numbers
An analog extension of an FXS port, FXS1 for example, of TGW4S can be associated with two phone
numbers, a PSTN number 61202701 and an extension number (1001for example). The PSTN number is
used for direct inward dialing and the extension number is used for intercom. This feature can be
supported by configuring the FXS1 number as 61202701 and adding the following routing rule to the
routing table:
FXS 1001 ROUTE FXS 1
Hunt Group
A hunt group is a group of extensions, to which an inbound call is terminated following certain rules.
Here is an example of how to terminate incoming calls from analog trunks to a hunt group consisting of
ports FXS1 and FXS2 in round-robin fashion:
FXO x ROUTE FXS 1-2/R
Outbound Call Barring
Restrict users from dialing certain telephone numbers, such as an international call. Examples are as
follows:
Routing Setting
Description
FXS[1] 0 ROUTE NONE
A call starting with 0 is barred from dialing using the phone set at FXS1
port.
FXS[1-2] 00 ROUTE
NONE
A call starting with 00 is barred from dialing using the phone set at
FXS1 to FXS2 port.
International call is not allowed.
FXS CPN2 ROUTE
NONE
The telephone whose calling number starts with 2 at a FXS port is
barred to call out.
Trunk Group for Outbound Calls
An outbound trunk group consists of a set of trunks which are used for outbound calling following certain
rules. Here is an example of routing all outbound calls from analog extensions to the trunk group
consisting of ports FXO1 to FXO4 in sequential fashion:
FXS x ROUTE FXO 1-4
Further, we set up the trunk group such that it is used only by calls to destinations with prefix 6120:
FXS 6120 ROUTE FXO 1-4
