How to Connect FreePBX Phone System to Yeastar TA FXO Gateway

The guide shows how to connect FreePBX phone system to TA FXO gateway via SIP trunk. With the connection of TA FXO gateway and asterisk FreePBX software, physical trunk PSTN will be extended on the open source PBX phone system. 

Features to be achieved after configuration:

1. Make outbound calls from FreePBX via the PSTN trunks of TA FXO gateway.
2. Receive calls from PSTN trunks of TA FXO gateway at FreePBX.

Basic Information Used in This Guide

Integration Mode:

FreePBX and TA FXO gateway are connected with Service provider mode (SPS trunk)

Firmware version:

In the guide, we tested TA410 and FreePBX phone system

TA410: 41.19.0.23

FreePBX: 10.13.66

Description：

IP address of FreePBX: 192.168.9.91

IP address of TA410: 192.168.9.90

A PSTN line from the provider is connected to TA410’s FXO port1

PSTN number: 05925503301

2. Preparation

All the TA FXO gateway attempts to contact a DHCP server in your network to obtain valid network settings (e.g., the IP address, subnet mask, default gateway address and DNS address) by default except TA410 and TA810.

Steps to set static IP for TA FXO gateway:

1. Download a DeviceFound tool from Yeastar website: FindTA.rar
2. Run the DeviceFound.exe software.
3. The detected TA devices in the local network will appear in the window.
4. Find the TA device’s IP address by the device’s MAC address or the SN.
5. Log in TAO gateway and go to System> Network Preferences> LAN Settings, disable DHCP and configure the LAN network, save and apply the changes, reboot TAO gateway to take effect.

3. Connect FreePBX Phone System to TA410 FXO Gateway

3.1 Create a SIP Trunk on FreePBX 

Step 1: Add a SIP (chan_pjsip) Trunk to TA410. Fill in the IP of TA410 in the “SIP Server” and “From Domain” field.

Path: Connectivity> Trunks> Add Trunk> Add SIP (chan_pjsip) Trunk

• Trunk name: TA410
• SIP Server: the IP of the TA410, 192.168.9.90
• SIP Server Port: the default port 5060, if you want to change the port, it means the FreePBX provide the port for other devices to register to it.
• From Domain: the IP of the TA410, 192.168.9.90

Step 2. Click “save” and “Apply change”, please check the status of the trunk, it shows “Avail” and “Not in use”

Path: Admin> Asterisk CLI> CLI command> execute “pjsip show endpoints”

3.2 Configuration on TA410 TA FXO Gateway

Step 1. Set a VoIP Server Template on TA410

Path: Gateway> VoIP Settings> VoIP Trunk> Add New Trunk

• Trunk Type: Service Provider
• Type: SIP
• Provider Name: FreePBX
• Hostname/IP: fill in FreePBX IP address, 192.168.9.91
• Domain: fill in FreePBX IP address, 192.168.9.91

Step2. After we create the trunk we can check the status of the trunk, it shows OK.

Path: Status> Port/Trunk Status

4. IP to Port 

In this section, we introduce how to achieve making outbound calls from FreePBX through PSTN line on TA410.

 

Figure 7 IP to Port

 

Step 1. Create one outbound route on FreePBX.

Path: Connectivity> Outbound Routes> Add Outbound Route

• Route Name: Name of the outbound route
• Trunk Sequence for Matched Routes: choose the trunk you want to use in the outbound route, TA410
• Dial Patterns: if you configure the prefix, it means that you should dial the number after the prefix. Match patterns means the number you dial should match it. For example, if the prefix is "9", the match pattern is "X.", and the number you want to dial is "5503300", then to dial the number via the route successfully, you need to dial "95503300".

Step 2. Configure “IP to Port” Route on TA410.

Path: Gateway> Routes Settings> IP->Port> Add IP->Port Route

Leave all the default settings on this page or you can change the Simple Mode to “NO” to configure the DID number if you to manage the call. And choose the source as SPS trunk with FreePBX and the destination is the PSTN line. 

• Route Name: from_FreePBX
• Call Source: choose the source of the call. For example, FreePBX.
• Call Destination: choose which PSTN trunk been chosen to dial out. For example, FXO1.

Step 3. Test a call from FreePBX

Now, you can use FreePBX phone system’s extension to make external calls through the PSTN 1 on TA410. Do not forget to add digit 9 before the called number, as the dial prefix is set to 9 on FreePBX outbound route. For example, if you want to call "15880270600", you need to dial "915880270600".

 

5. Port to IP

In this section, we introduce how to achieve making incoming calls to FreePBX through PSTN trunk on TA410.

Figure 10 Port to IP

 

Step 1. Create an inbound route on FreePBX.

Path: Connectivity> Inbound Routes> Add Inbound Route

• Description: the name of the inbound route, from_TA410
• DID Number: if the trunk want to pass the DID on the incoming calls, please configure 888
• Set Destination: choose the destination of the inbound route. Extension 300

Figure 11 Inbound Route on FreePBX Phone System

 

Step 2. Configure “Port to IP” Route on TA410

Path: Gateway> Routes Settings> Port->IP> Add Port->IP/Port Route

Choose Simple Mode to “No” and set Hotline to 888, which is the same number with the DID number set on FreePBX Inbound route.

• Route Name: to_FreePBX
• Call Source: choose the source of the call. For example, Port-FXO1.
• Call Destination: choose which PSTN trunk been chosen to dial out. For example, FreePBX.
• Hotline: the hotline number should be the same as the DID number configured in the inbound route of FreePBX side

Step 3. Test a call.

Dial the PSTN trunk number 05925503301 on your cell phone, the call will be routed to FreePBX extension 300.
