How to configure Mediatrix 1204 four port analog FXO gateway

Configuring the Mediatrix 1204 using Unit Manager Express

Connecting Unit Manager Express to the 1204 Unit

The following configuration example describes how to use the Mediatrix 1204 analog 4 port FXO gateway as a local PSTN gateway with sipX. Mediatrix chose SNMP as the interface and protocol used to configure and administer their gateways. SNMP is not easy to deal with at the MIB level, so if you are not familiar with SNMP we recommend to chose another gateway manufacturer.

...

Once Unit Manager Express and the corresponding MIB tree definitions are installed, you should be able to fire up Unit Manager Express and connect to the 1204 gateway. By default the 1204 unit obtains its IP address using DHCP. Therefore, you might want to use the Discoer Agents function under the SNMP tab in Unit Manager Express. Once found click on the gateway and connect. The icon in the footer of Unit Manager Express should now show connected.

Configuring the 1204 Unit

The Mediatrix should be configured with a static IP Address rather than a DHCP address. If DHCP is used a specific IP addressed should be reserved for the Mediatrix gateway based on its MAC address.

The Mediatrix 1204 FXO gateway technically is a SIP user agent. However, it is not an endpoint we want to call and therefore it does not need to register with sipX. Calls are routed to the gateway based on rules defined in the dialplan active on sipX.Note:

Note
When connecting an FXS gateway like the Mediatrix 1102, 1104 and 1124 (that connects to an analog phone), you would want the gateway to register with sipX, so that this line can be assigned to a user that has an extension number, voicemail box, etc.

Configuring telephony attributes below tells the FXO gateway to automatically route incoming calls from the PSTN to the auto-attendant.Note:

Note
If you change the extension number for the auto-attendant in sipX, you also have to change the setting below.

Defining a new PSTN gateway in sipX

Setting up a new gateway in sipX is really simple. Go to the Gateways in the left navigation bar, enter a unique name for the gateway and its IP address. Done. You can now use this gateway in all your dial plan definitions, which allows you to define specific rules about which calls should be routed to which gateway.

IMPORTANT:

Note
Connect at least one PSTN line to the gateway before testing your setup. The gateway will reject all calls (the in use LED will not come on) unless it can connect to an external line.

Reset to Factory Defaults

Reset to factory defaults can be done at run time or while powering up the unit. The procedure is the same: Insert a paper clip into the Default Settings hole at the back next to the Ethernet plug. Hold it in place until all four LEDs stop blinking and are steadily ON (10 to 15 seconds), then depress. Resetting to factory defaults deletes all configuration and history stored in the unit. Factory Defaults configures the unit to obtain an IP address from a DHCP server - make sure you got one on your network.

Mediatrix Analog Gateway Firmware Upgrade

You are an expert in SNMP management and MIB variables, right? If not I suggest you leave this task to an expert. Mediatrix only gives access to firmware downloads to their certified resellers, so that you have to contact your dealer to obtain a new firmware release. The firmware package includes the new image .zip file, updated documentation, as well as the MIB definition that corresponds to the new firmware image. In addition, you will need a recent copy of Unit Manager Express, the Mediatrix management tool.

...

Start Unit Manager Express and navigate the following variables:

Check Automatic Get in Unit Manager Express. Click on Set everytime you changed a variable to save.
