Configuring network settings for the devices on the Internal network

Example FortiGate Voice branch office configuration

Configuring network settings for the devices on the Internal network

You can configure the PCs and other devices on the internal network to get their network configuration automatically using DHCP. If required you can also configure devices on the internal network with static IP addresses on the 172.20.120.0 subnet but outside the range awarded by the FortiGate Voice DHCP server. Example static TCP/IP configuration:

IP Address

172.20.120.20

Subnet Mask

255.255.255.0

Default Gateway

172.20.120.10

DNS Server

172.20.120.10

You can also use the same network configuration for the SIP phones on the internal network.

Configuring the FortiGate Voice PSTN and PBX settings

The procedures in this section describe how to configure the FortiGate Voice unit as the PBX for SIP phones on the branch office internal network. These procedures describe how to configure many of the FortiGate Voice PSTN and PBX features. PSTN features are supported on some FortiGate Voice models. The following procedures are included:

To configure the fxo1 PSTN interface

To configure basic PBX system and voicemail notification settings

To add a VoIP provider

To add a dial plan for dialing the PSTN and the main office

To add the extensions that are on the branch office internal network

To configure the fxo1 PSTN interface

This procedure describes how to configure the FortiGate Voice fxo1 PSTN interface to connect the FortiGate Voice unit to one PSTN phone line. If you have more PSTN phone lines you can connect and configure more fxo interfaces. Skip this procedure if your FortiGate Voice unit does not include PSTN interfaces.

1Go to System > Network > PSTN Interface and edit the fxo1 interface.

2Configure the following settings.

Phone Number

Enter the phone number of the PSTN phone line as provided by your

 

phone service provider.

 

The phone number is used for caller ID for calls from the FortiGate

 

Voice unit to the PSTN. It can be any number, but is usually the

 

actual phone number of the PSTN line connected to the fxo1

 

interface. Area code and country codes are optional.

Display Name

This name is used for caller ID for calls from the FortiGate Voice unit

 

to the PSTN. It can be any name, such as a company name, that

 

identifies the branch office.

Caller ID Options

Configure the following options to support caller ID functions for calls

 

from the internal network to the PSTN.

Catch Caller ID

Select to enable the FortiGate Voice unit to receive caller ID

 

information from calls originating on the PSTN and send the caller ID

 

information to the extension that answers the call.
