Mediatrix Digital Gateway with ISDN Telephones

This document outlines the configuration steps to set up one Mediatrix digital gateway to provide voice over IP (VoIP) connectivity to ISDN telephones in a corporate network environment.

The Mediatrix gateway is used to connect the ISDN telephones to an existing VoIP network. .

The steps described in the following pages will show you how to setup the Mediatrix unit so it can:
  • Receive calls from the ISDN phones and route them to a remote branch through the VoIP network (e.g. from Office A to Office B)
    • A user from Office A picks up an ISDN phone and dials a number.
    • The Mediatrix gateway forwards the call to the appropriate Mediatrix unit.
    • The Mediatrix unit makes the appropriate analog phone ring.
    • A user in Office B picks up the analog phone and the call is established.
  • Receive calls from remote branches through the VoIP network and route them on one of the local branch's ISDN phones (e.g. from Office B to Office A)
    • A user from Office B picks up an analog phone and dials a number.
    • The appropriate Mediatrix unit routes the call to the Mediatrix gateway.
    • The Mediatrix routes this call to the appropriate ISDN BRI interface based on the dialled number.
    • The appropriate ISDN phone rings.
    • A user from Office A picks up the ISDN phone and the call is established.

Information to Know Before Starting

Before starting to use these configuration notes, complete the following table to make sure you have the required information to complete the different steps.

Note: The Mediatrix unit is configured in the NT mode. The ISDN ports of the Mediatrix Gateway, i.e BRI ports, must first be configured. For the complete ISDN configuration information, refer to the ISDN User Guide published on the Media5 documentation portal at https://documentation.media5corp.com/
Note: If you are not familiar with the meaning of the fields and buttons, click Show Help, located at the upper right corner of the Web page. When activated, the fields and buttons that offer online help will change to green and if you hover over them, the description will be displayed.
Note: The Mediatrix unit must be reinitialised to its factory default settings to make sure the configuration can be successfully executed.
This document includes the basic configuration of a gateway to use ISDN phones (BRI interfaces). If you wish to add registration and authentication, refer to the Technical Bulletin - Basic SIP Unit Registration and DGW Configuration Guide - SIP Authentication documentation published on the Media5 documentation portal at https://documentation.media5corp.com/

Configuration of the Mediatrix Digital Gateway

Logging on to the Mediatrix Unit Web Interface

Before you begin
The computer IP address must be in the same TCP/IP network as the Mediatrix unit.
About this task
For better performances, it is recommended to use the latest available version of Microsoft Internet Explorer, Google Chrome, or Mozilla Firefox.
Note: You may not be able to log on to the Mediatrix unit Web interface if you are using older browser versions.
Procedure
  1. In your Web browser, enter the IP address at which the Web interface of your Mediatrix unit can be reached.
    • If your network has an IPv4 DHCP server, connect the primary Ethernet port of the Mediatrix unit to the network (ETH1 port), use the provided DHCP server IP address.
    • You can also connect your computer to the secondary Ethernet port of the Mediatrix unit (ETH2), use the 192.168.0.10 IP address. However, the computer must also own an IP address in the 192.168.0.0/24 network.
  2. Enter admin as your username and administrator as the password.
    Note: You can also use public as a username and leave the password field empty; it has the full administration rights by default.
  3. Click Login.
Results
The Information page of the Web interface is displayed.

Configuring the Uplink Network Interface to a static IP address

Steps
  1. Go to Network/Interfaces.
  2. In the Network Interface Configuration table, from the Link selection list located next to Uplink, leave the default value, i.e. ETH1.
  3. From the Type selection list, select IpStatic (IPv4 Static).
    Note: The Uplink Network Interface must be set with a fixed public IP address for the NAT/router to be able to do port-forwarding to the unit. It will also be easier for the PBX to communicate with the unit if the address is static.
  4. In the Static IP Address field enter the assigned static IP address.
  5. From the Activation selection list, select Enable.
  6. Click Apply to apply all changes to the configuration.
    Note: Once the changes are applied, the connection with the unit might be lost. You may need to reconnect to the Web page using the new address.
Result
The unit can be reached (via the Web) through the Uplink static IP address

  4. Click Apply to apply all changes to the configuration.
    Note: A Warning message is displayed, but this is normal.
  5. Click Apply.
    Note: Once the changes are applied, the connection with the unit might be lost. You may need to reconnect to the web page using the new address.
Result
The Lan1 Network Interface will be available in all the lists of the Management Interface where a Network Interface needs to be selected. For example, in the Local Firewall, and Configuration pages.

  3. Click Start Sensing.
    Note: Launching the Automatic Configuration may terminate abruptly all ongoing ISDN calls. The auto-configuration may take some time to complete and some of the current ISDN configuration settings might be replaced by new values.
Result
Under ISDN/Status, the Physical Link and Signaling fields of each interface should indicate Up.

DGW Documentation

Mediatrix units are supplied with an exhaustive set of documentation.

Mediatrix user documentation is available on the Media5 Documentation Portal at http://documentation.media5corp.com

Several types of documents were created to clearly present the information you are looking for. Our documentation includes:

  • Release notes: Generated at each GA release, this document includes the known and solved issues of the software. It also outlines the changes and the new features the release includes.
  • Configuration notes: These documents are created to facilitate the configuration of a specific use case. They address a configuration aspect we consider that most users will need to perform. However, in some cases, a configuration note is created after receiving a question from a customer. They provide standard step-by-step procedures detailing the values of the parameters to use. They provide a means of validation and present some conceptual information. The configuration notes are specifically created to guide the user through an aspect of the configuration.
  • Technical bulletins: These documents are created to facilitate the configuration of a specific technical action, such as performing a firmware upgrade.
  • Hardware installation guide: They provide the detailed procedure on how to safely and adequately install the unit. It provides information on card installation, cable connections, and how to access for the first time the Management interface.
  • User guide: The user guide explains how to customise to your needs the configuration of the unit. Although this document is task oriented, it provides conceptual information to help the user understand the purpose and impact of each task. The User Guide will provide information such as where and how TR-069 can be configured in the Management Interface, how to set firewalls, or how to use the CLI to configure parameters that are not available in the Management Interface.
  • Reference guide: This exhaustive document has been created for advanced users. It includes a description of all the parameters used by all the services of the Mediatrix units. You will find, for example, scripts to configure a specific parameter, notification messages sent by a service, or an action description used to create Rulesets. This document includes reference information such as a dictionary, and it does not include any step-by-step procedures.
