31.14.5 FXS Gateway Configuration

The following procedure describes how to configure the FXS interface (at the 'remote PBX
extension').

To configure the FXS interface:
1. In the Trunk Group table (see Configuring Trunk Group Table), assign the phone
numbers 100 to 104 to the device's endpoints.
Figure 31-12: Assigning Phone Numbers to FXS Endpoints
2. In the Automatic Dialing page (see ''Configuring Automatic Dialing'' on page 478),
enter the phone numbers of the FXO device in the 'Destination Phone Number' fields.
When a phone connected to Port #1 off-hooks, the FXS device automatically dials the
number '200'.
3. In the Outbound IP Routing table (see ''Configuring Outbound IP Routing Table'' on
page 397), enter 20 for the destination phone prefix, and 10.1.10.2 for the IP address
of the FXO device.
Note: For the transfer to function in remote PBX extensions, Hold must be disabled at
the FXS device (i.e., Enable Hold = 0) and hook-flash must be transferred from the
FXS to the FXO (HookFlashOption = 4).
