Mediatrix 1204 Configuration Notes

E-mail Print PDF

The Mediatrix 1204 is a high-quality 4-port FXO gateway for IP phone systems.

Preparation

Configuration of the unit is generally done with an SNMP MIB browser.  It does have a rudimentary web interface, but it is not sufficient to program the unit.

Download and install the UMN (Unit Network Manager) from here.  You'll need a Windows PC.

Intall the UMN MIB Pack that comes in the downloaded zip file.

Configuration

Mediatrix 1204's default to using DHCP to get their IP address.  If they can't get an address that way, they default to 192.168.0.1.  Be careful if you reset to factory defaults as the unit may 'step on' some other important device on your network.

Set to Factory Defaults

With a paper clip, press and hold the recessed reset button while powering the unit on.  Keep holding the reset button until all four LED's stop flashing, then release.

The unit will then address itself via DHCP or will default to 192.168.0.1 failing that.

Be patient, the unit seems to take a while before it becomes accessible via HTTP or the SNMP MIB browser (UMN).

The default username and password is 'admin' and '1234'.

Unit Manager Network

Use the Unit Manager SNMP management software that came with the Mediatrix 1204 to configure it..  You can download it from here near the bottom of the list in the section "Software Applications".  The web interface on the 1204 is incomplete.

Using a Mediatrix 1204 FXO Gateway with Asterisk

Here are settings I have used for various Asterisk PBX installations.  Essentially, I only use IP authentication to get it to work.  There are probably other, better ways to do this.

Start UMN.  Just click OK at the login prompt.  Run the autodetect feature.  It takes a while, but you can speed it up by limiting the scan range.

Select 'Unit Manager' in the left pane.

Right-click + Autodetect to scan for the 1204.  Limit the IP range if you can because the scanning is slow.

Select 'Administration' under the detected unit in the left pane (a tree item). Right-click + Edit

Set IP configuration, if you want to change it. Click Ok

Select the detected unit in the left pane. Right-click + Edit SNMP

Check Automatic GET

Change the following attributes:

iso/org/dod/internet/private/enterprises/mediatrix/mediatrixConfig/ipAddressConfig/ipAdressConfigSipServer/ipAdressConfigSipServerStatic/

sipHomeDomainProxyStaticHost

Set to your PBX IP address

iso/org/dod/internet/private/enterprises/mediatrix/mediatrixConfig/voiceIfMIB/voiceIfMIBObjects/voiceIfTable/voiceIfEntry/

voiceIfG711VoiceActivityDetectionEnable

Change from: conservative > disable

voiceIfG711ComfortNoiseGenerationEnable

Change from: customNoise > disable

iso/org/dod/internet/private/enterprises/mediatrix/mediatrixConfig/voiceIfMIB/voiceIfMIBObjects/voiceIfDtmfTransportTable/voiceIfDtmfTransportEntry/

voiceIfDtmfTransport

Change from: inBand > outOfBandUsingRtp

voiceIfDtmfPayloadType

Change from: 96 > 101

iso/org/dod/internet/private/enterprises/mediatrix/mediatrixConfig/telephonyAttributesMIB/telephonyAttributesMIBObjects/telephonyAttributesIfFeaturesTable/telephonyAttributesIfFeaturesEntry/

telephonyAttributesAutomaticCallEnable

Change from: disable > enable

telephonyAttributesAutomaticCallTargetAddress

For each FXO port, enter the extension on the PBX to transfer inbound calls to, perhaps an IVR

telephonyAttributesAutomaticCallDirectionRestriction

Ensure 'noRestriction' is selected (default)

telephonyAttributesAutomaticHookFlashProcessing

Ensure 'processLocally' is selected (default)

iso/org/dod/internet/private/enterprises/mediatrix/mediatrixIpTelephonySignaling/Sip/SipMIB/SipMIBObjects/sipUAIfTable/sipUAIfEntry/

sipUAMainUsername

Set all ports to 'NO-CLID' as this will be used in place of CLID if there is no CLID on incoming call/trunk.

Logging

Select 'Administration' under the detected unit in the left pane (a tree item). Right-click + Edit

Select 'Static' and set the syslog server IP address. Click Ok

On a Linux syslog server, enable remote logging:

vi /etc/sysconfig/syslog

add '-r' to SYSLOGD_OPTIONS

service syslog restart

Firmware Update

Download the latest firmware from here.

Extract the '1204' folder and drop it into the root of your TFTP server and assign 'read' permissions to all files.

In the Mediatrix web interface, go to:

Management -> Firmware Download -> General

Set:

Source: Static
Protocol: TFTP
Host: [your-server-ip]
Port: 69
Provision Source: Static
Firmware Location: /1204

Management -> Firmware Download -> Automatic Update

Set:

Firmware Download On Restart: Enable

Save, then reboot the unit.  It takes a few minutes...don't interrupt it.

If you have logging configured, you can see what is happening:

tail -f /var/log/messages

or

tail -f /var/log/syslog

You will probably want to reset 'Firmware Download On Restart' back to Disabled.
