3 Introduction FortiVoice-VM is the virtual appliance version of the award winning FortiVoice Enterprise Phone System. It supports the most popular virtualization environment such as Vmware ESXi, Microsoft Hyper-V, Citrix Xenserver and open source KVM. It comes with all the nice features that FortiVoice Enterprise phone system offers and has the flexibility to scale with stackable license. The only limitation is that it doesn t have any traditional PSTN ports. In case you are using traditional analogue PSTN lines, instead of VoIP SIP trunk, you can use Grandstream PSTN gateway, such as GXW 4104 (4 FXO) or 4108 (8 FXO). For example, GXW4104 uses FXO ports to connect to the service provider with FXO ports and uses IP connection (LAN port) to connect to FVC-VM. The following network diagram shows how FortiVoice-VM is connected with the Grandstream gateway: In this scenario, FortiFone uses a dynamic IP address with a third-party DHCP server. The FortiFone will be configured with auto-provisioning. There is no dedicated VLAN for voice. The Grandstream GXW4104 gateway can be connected to the FVC-VM in one of the two methods: Method 1: Configure GXW410x with SIP accounts in IP PBX, which will enable you to put GXW-410x behind a NAT/Firewall (used for one-stage and two-stage dialing). Method 2: Configure GXW410x to function as a PEER gateway (no SIP accounts are needed; this is only used for one-stage dialing). This guide uses method 2, which configures the gateway as a peer office and doesn t require registration for simplicity. 3

4 Configuration Procedures This guide assumes that you use FortiVoice-VM version The same configuration also applies to the other platforms of the FortiVoice Enterprise Phone System. This configuration example includes the following procedures: Provisioning SIP extensions on FortiVoice Configuring FortiVoice to connect with PSTN gateway Configuring Grandstream GXW4104 Gateway Verifying the configuration Part 1: Provisioning SIP extensions on FortiVoice 1. On the FortiVoice-VM web GUI, go to Phone System > Advanced Setting > Autoprovisioning and enable auto-provisioning. By default it is turned off. 4

5 2. Go to Extensions > Extensions > IP Extensions and add a SIP extension with its MAC address. 3. Factory reset the FortiFone from the LCD panel by pressing the Menu button and then number 6. It should reboot and register with the SIP extension configured in the previous step. The phone may require an extra reboot during the provisioning process. 5

6 Part 2: Configuring FortiVoice to connect with PSTN gateway 1. On the FortiVoice-VM web GUI, go to Trunks > Office Peers and add the GXW4104 gateway as a peer office. Enter the IP address of the gateway as remote server and leave Authentication Settings unchecked for simplicity. 6

7 2. Go to Call Routing > Outbound and add outbound call routing rules to direct outgoing calls to GXW4104 from FortiVoice. In this example, all calls to destination numbers longer than 7 digits (presented by seven X and one dot) will be forwarded to the PSTN lines connected to the Grandstream gateway. Remember to select the peer office created in the previous step as the trunk in call handling. 7

8 3. Go to Call Routing > Inbound and add inbound call routing rules for incoming calls from GXW4104 gateway. In this example, we forward all the incoming calls to the extension provisioned previously as following: 8

9 4. If you have more than one extension, you can forward incoming calls to the auto-attendant so that the caller can enter the desired extension number when being prompted: 9

10 Part 3: Configuring Grandstream GXW4104 Gateway 1. Connect the WAN port of GXW4104 to your network switch and it will be assigned an IP address by your internal DHCP server. You can download the IPQuery tool from Grandstream website to find its IP address. Connect to the web interface of GXW4104 by entering the IP address found into your browser. The default administrator password is admin. 2. Create an account with the FortiVoice IP address as the SIP server. The account name can be any string you like. 10

11 3. Disable SIP registration for the account you just created. 4. Add a channel using the account created above. Authenticate ID and Authen Password can be left blank as they are not enabled on the FortiVoice side. They can be enabled later on both ends once the two-way communication is verified. 11

12 5. Configure channel settings to unconditionally forward calls from PSTN to FortiVoice. 6. Set the dialing method to 1 stage. 12

13 Part 4: Verifying the configuration Once the configuration on both Grandstream gateway and FortiVoice is complete, you can proceed to verify your setup: 1. Verify the incoming call from the PSTN side to SIP side. Make an incoming call from PSTN side to the number(s) attached to the phone line connected to Grandstream PSTN port (FXO). Make sure your FortiFone can receive the phone call and the caller ID can display properly. 2. Verify the outgoing call from SIP side to PSTN side. Make an outgoing test call from FortiFone using the destination number pattern defined in the outbound call routing rule on FortiVoice so that they can be forwarded to PSTN gateway. Make sure the call is successful and caller ID is displayed properly on callee s phone. References 1.
