To configure FortiFones behind a NAT device on the internal network
The configuration for FortiFones behind a NAT device on the internal network is the same as for FortiFones directly on the Internal network. See “To configure FortiFones on the internal network” on page 27.
You may have to configure the NAT device to allow SIP sessions between the FortiFone and the FortiGate Voice unit.
To configure FortiFones behind a NAT device on a remote network
The following steps describe how to configure a FortiFone on the remote network with extension number 6010.
1Connect and power on the FortiFone handset.
2Connect to the handset web configuration interface.
The default web configuration interface address is http://192.168.0.1. To connect to this address from a PC, your PC should have an IP address on the 192.168.0.0 subnet, for example: 192.168.0.10/255.255.255.0.
The default Username is root. No password is required.
3Go to Network > LAN Settings and set the IP Type to DHCP Client and select Submit.
4Select Save & Reboot to save the IP addressing change.
5Log into the FortiFone using the IP address it acquired from the DHCP server.
6Go to SIP Settings > Service Domain and add the following configuration information:
Active | On |
Display Name | The name to be displayed on the phone. This name is only |
| displayed on this phone. When this phone calls another phone |
| the name displayed is the First Name and Last Name added to |
| the FortiGate Voice Extension configuration. |
User Name | 6010 |
| This is actually the Line Number or Extension Number and must |
| match the Extension Number added to the FortiGate Voice |
| Extension configuration for this phone. |
Register Name | 6010 |
| The Register Name is used to authenticate the FortiFone and |
| must match the Extension Number added to the FortiGate Voice |
| Extension configuration for this phone. Both the User Name and |
| Register Name are required. |
Register Password | The Password added to the FortiGate Voice Extension |
| configuration for this phone. The Register Name and Register |
| Password are used to authenticate the phone with the FortiGate |
| Voice unit. |
Domain Server | Leave this field blank. |
| Not required since the configuration uses the FortiGate Voice |
| unit as a SIP proxy. This field is only used to add the phone to a |
| SIP service domain. |
