7.12.4.4 Call Waiting for Remote Extensions

When the FXO device detects a Call Waiting indication (FSK data of the Caller Id -
CallerIDType2) from the PBX, it sends a proprietary INFO message, which includes the
caller identification to the FXS device. Once the FXS device receives this INFO message, it
plays a call waiting tone and sends the caller ID to the relevant port for display. The remote
extension connected to the FXS device can toggle between calls using the Hook Flash
button.

7.12.4.5 FXS Gateway Configuration

The procedure below describes how to configure the FXS device (at the 'remote PBX
extension').
To configure the FXS interface, take these 3 steps:
1. In the 'Endpoint Phone Numbers' page (refer to Configuring the Endpoint Phone
Numbers on page 179, assign the phone numbers 100 to 107 to the device's
endpoints.
Figure 7-12: Assigning Phone Numbers to FXS Endpoints
2. In the 'Automatic Dialing' page (refer to ''Automatic Dialing'' on page 173), 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'.
