This document outlines the configuration steps for deploying Mediatrix 4100 series FXS units in an MGCP environment with a generic MGCP soft-switch.
This is a typical deployment scenario of Mediatrix 41xx in a MGCP-based MTU/MDU environment. The gateways provide connectivity to analog phones and fax machines and analog trunking to legacy PBX/KSU (for small business) in each building floor, whereas the softswitch provides call control and telephony services for all gateways.
This configuration note was written and validated using the following platforms and versions.
The following configuration notes are not a substitute for the Mediatrix Administration Documentation for Mediatrix analog products. Please have the following manuals available for reference:
The Unit Manager Network (UMN) software is a configuration and management tool for Mediatrix devices. The UMN can be downloaded from the Mediatrix Support Portal: https://support.mediatrix.com/DownloadPlus/Download.asp. It has a default 3-units limit upon installation. This will suffice for most configurations.
It is recommended that the administrator uses the UMN to configure the Mediatrix devices. Please refer to the UMN Quick Start guide for the installation of the software. Once the UMN software has been installed on your PC1, proceed with the following steps.
Step 1: Start the UMN
Step 2: Login to the UMN
Step 3: Perform an Autodetect
Note: The UMN runs in the Windows background. Mediatrix highly recommends that the administrator stops and restarts the
UMN service whenever the IP address of the PC is changed. A restart may be needed depending on your Windows O/S.
Configuring Network Parameters
Setting Basic Network Parameters
Step 1: Setting up Call Agent IP Addresses
On the Mediatrix FXS unit, the Call Agent IP addresses can be statically assigned or acquired by DHCP. In this example, the Use DHCP option is unchecked, i.e., only static addresses are used. The IP address of your MGCP Call Agent, 126.96.36.199, is manually assigned in the Call Agent section.
Step 2: Setting up the MGCP Local Configuration
In this example, the MGCP listening port is set to 2427; this is the default value for Mediatrix and should NOT be changed unless your softswitch is using another port number.
The RSIP restart Level is set to Group by default and please match it with your soft-witch setting.
Step 3: Define FQDN
The FQDN Mode specifies the method used to obtain the required information (hostname or IP address of the source unit) forMediatrix unit to use in the MGCP signaling message.
There are four options:
In this example, the Static option is used as a FQDN Mode and Mediatrix1234 is the pre-defined name for this endpoint that will be sending registration message to the softswitch call agent.
Note: The FQDN of all the gateways need to be provisioned in advance. Refer to your softswitch Documentation for more details.
Step 4: Define IdTerm
In this example, the MGCP IdTerm1 and IdTerm2 are configured to the Mediatrix default values. These values should match the values given in the softswitch Signalling Server.
Step 5: Restart the unit
Once the Mediatrix 41xx is in service, you are ready to make voice and fax calls across the VoIP network.
Step 1: Enabling VLAN Tagging
The Mediatrix units that posses a second Ethernet port can be configured to perform VLAN Tagging for traffic prioritization. The unit can assign a different VLAN tagging to the DATA traffic generated in the LAN port by enabling the VLAN Tagging Substitution capability. This feature is mainly used with IP environments where DATA & VOICE packets receive different treatment across the network according the VLAN Tagging assigned.
To enable VLAN Tagging for VOICE packets generated in a Mediatrix unit, open the Edit SNMP… option by right-clicking the unit in the UMN and set the following:
To enable VLAN Tagging Substitution for DATA packets generated behind the Mediatrix unit, open the Edit SNMP… by right-clicking the unit in the UMN and set the following:
Step 2: Set Static IP Address for Management at Ethernet Port 2
Once VLAN Tagging is enabled after restarting the unit, the Mediatrix unit is accessible for management with a computer within the VLAN network only. For easy management, the administrator can set a static IP address to the second Ethernet port so provisioning & troubleshooting is still available from a computer connected to this port.
To set a static IP address to the second Ethernet port, in the Mediatrix unit, open the Edit SNMP… option by right-clicking the unit in the UMN and set the following:
