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 Groups), assign the phone numbers 100 to 104 to the device's FXS ports. |
| 2. | In the Automatic Dialing table (see Configuring Automatic Dialing), configure automatic dialing for the FXS ports to dial the FXO endpoints, as shown in the figure below. For example, when the phone connected to FXS Port #1 off-hooks, the device automatically dials the number "200". |
| 3. | In the Tel-to-IP Routing table (see Configuring Tel-to-IP Routing Rules), enter 20 for the destination phone prefix and 10.1.10.2 for the IP address of the FXO device. |
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).
