Patton FXS Supported models

This guide is provided as is and no longer updated. Please contact vendor for support on how to connect them to 3CX

Supported Models: Patton SmartNode SN4112 and SN4114

FXS gateways connect internal analog devices such as fax machines and phones, and register them as extensions / fax extensions to your 3CX. Those extensions can be addressed as normal phones however their functionality is limited due to the capabilities of the analog technology.

Notes:

  • Trinity Firmware is NOT supported for these devices.

This guide focuses on the setup of FXS. If you are looking for another technology:

Prepare the Patton FXS Gateway

In order to identify your FXS gateway IP address follow our guide “How to Use the Patton Discovery Tool”. Once the device is detected, download and upgrade the firmware of your Patton FXS gateway. Note: All templates are designed to work with Patton SmartWare firmware and the device should run on the “latest 6.X firmware”. Trinity Firmware/Devices are currently NOT supported.

To update the firmware:

  1. Open your web-browser to your FXS gateway IP address retrieved in the previous step.
  2. Login to your account (Default username: administrator, password: leave empty).
  3. Navigate to “Import/Export” → “Import Firmware” → and in “Download Firmware” choose your firmware .zip file downloaded and then press “Import”.

Step 1: Add and Choose Device

Navigate to “Voice & Chat” within the 3CX Admin Console and select “Add DECT / FXS”:

  1. Select model/device: Patton 2 Ports FXS GW or Patton 4 Ports FXS GW
  2. MAC Address: Enter the FXS device’s MAC address (underneath the device)
  3. Press “Next” to select the provisioning method: choose from “Local LAN/VPN" or “Connect via SBC/ router phone” depending on your setup.

Step 2: FXS Line Setup

You need to define the device and line specific options:

  1. Gateway IP address: Enter your Patton FXS device’s IP address.
    (the IP address will be set to static in case DHCP is being used)
  2. Gateway SIP Port: Enter 5060
  3. Subnet Mask: Enter your Network Mask size (e.g. 255.255.255.0).
  4. FAX Transmission Mode: In this section select how the Patton gateway should handle fax connections. In case your VoIP provider supports T38 or you have a Patton FXO or ISDN configured for T38 then set the codec to T38. However if you are running a VoIP Provider which does not support the T.38 protocol, select “Fax in Audio”. In T.38 mode the Patton FXS device will actively switch to the T.38 protocol once the call is established.
  5. Tone Set: Define in which country you are using this device. If the country is not listed, request from your telco the used tone set of your line.

Step 3: Map extensions

Follow the above image in order to define which extensions will be using each port on the FXS gateway. In the example above, port 1 on the FXS Gateway will be mapped to extension 001, port 2 will be mapped to extension 002 and so on. Finalize the configuration by saving the config with “OK”.

Note: If you plan on using fax machines on the FXS gateway, please create dedicated fax extensions in the “Fax Extension” menu (Refer to step 5 for information on how to do this).

Step 4: Provision the Gateway

Reopen the just created FXS device and click on the “Provisioning URL”. A file will be downloaded to your PC which will be used in a few moments.

  1. Open your web browser and connect to your Patton FXS device.
  2. Log in (default username: administrator, no password is required (blank field))
  3. Navigate to the “Import Configuration” page (e.g. http://192.168.9.163/imp-cfg.html whereby the gateways IP address is 192.168.9.163).
  4. Upload the configuration file onto the Patton device by using the “Choose File” and “Import” button.

Patton FXS - Import configuration

  1. In order for the configuration to be applied, reload the device. The mapped extension will now be visible in the “Phones” tab (except fax extensions, which will be shown in the “System Extension” tab).

Step 5: Add Fax extension (Optional)

In case you are using fax machines connected to your FXS gateway, “Fax Extensions” must be used instead of using a regular extension. You can do so by:

  1. Go to Admin > Advanced > Fax and click on Add.
  2. Set these options for the new fax extension:
  1. “FAX Extension Number” - set the extension number.
  2. “Fax Extension Authentication ID” - accept default or set your own.
  3. “Fax Extension Authentication Password” - accept default or set your own.
  4. “Default Caller ID” - optionally set caller ID.
  1. Press “OK” to save the fax extension.
