3 First Steps Identifying your MAC Address The MAC address of a Mediatrix unit is printed on a sticker underneath the device. Identifying your Dynamic IP Address There are two ways to find the IP address of a Mediatrix 4400 unit. On first boot, the Mediatrix 4400 attempts to get its IP address via DHCP. If there is no DHCP server on the network, you must assign it a static IP address. See the next section Using a static IP address. The DHCP server logs or database can be searched by matching the MAC address to the assigned IP address. Start a network capture program, such as Wireshark, and look for bootp protocol packets. This can be done by setting bootp as a filter. The DHCP Offer or DHCP request messages contain the IP address assigned to the unit. You can download the latest Wireshark version from Page 3 of 24

4 Using a Static IP Address Configuration Notes 291 If no DHCP server is available, connect directly to the unit to configure it. If a DHCP server is available as described above, skip to the next section. 1. Configure your computer with a static IP address in the /24 subnet. For example, set the IP address of your computer to The Mediatrix rescue interface uses the address by default. 2. Connect the computer directly to the Mediatrix 4400 Ethernet port (Network port if you have a 2 Ethernet ports version), or through a hub or switch, with a regular Ethernet cable, no cross-over cable is needed. 3. Perform a Recovery Mode reset. Using a paper clip, press the eset button at the back of the unit for more than 5 seconds, until all the LEDs start blinking. Release the paper clip. If the LEDs are all turned on and have stopped blinking, you held the paper clip too long and did a Factory Reset (all settings erased). Start the Recovery Reset again. Page 4 of 24

5 Logging in the Unit 1. Put the IP address of the Mediatrix 4400 unit in your internet browser. 2. In the login screen, enter the username public. Leave the password field empty. Click the Login button. Configuration Notes 291 IMPORTANT!!! In the Management > Misc tab, enable the management for all interfaces. If the management interface is Rescue only, you may not be able to access the web page when out of the Recovery Mode. Page 5 of 24

6 Configuring the Hardware Tab Configuration Notes 291 If required, enable Power Feeding for the desired BRI ports. The Clock Reference parameter in the Unit Configuration section is used to synchronise the other BRI ports on a specific BRI. For example, ports 2, 3 and 4 can be synchronised with a PSTN line in BRI port 1. If no clock reference is selected, the Mediatrix unit uses its own internal clock for synchronisation. Configuring the Syslog Server Under System->Syslog, enter the IP address of the syslog server in the Remote Host field. If you are gathering packets using Wireshark, you can also use the IP of the PC that takes the Wireshark capture. Page 6 of 24

7 Depending on how much information is needed, the TAC Diagnostic Traces can be enabled at the bottom of the page. Click Submit. Before sending any debug trace to Media5, make sure that Diagnostic Traces are enabled and that the syslog Service Severity levels are set to Debug. WARNING: The TAC Diagnostic Traces generate a lot of traffic and may affect call quality when the gateway is fully loaded (for example a 3632 using the 2 slots (60 channels)). Network Configure the Network Parameters If a DHCP server was used to obtain an IP address and you do not need to modify any network parameters, skip to the ISDN configuration section. If the recovery mode was used to assign a static IP address or if a modification to the existing static configuration is needed, begin by configuring the default router first. You can also modify your DNS and SNTP settings. Page 7 of 24

8 Configure the desired static IP addresses, and do not forget to put a /XX, which represents your network mask. When done, enable the Uplink interface, disable the rescue interface and click the Submit button. WARNING: When you click Submit, the unit applies the configured network parameters. To access the unit configuration page after this modification, point your browser to the newly configured IP address of the Uplink interface. Page 8 of 24

9 ISDN Configuration BRI Ports Configuration All ports can be individually configured. Select the proper port by using the Select Interface drop-down menu. Important Variables Descriptions Pay particular attention to the following variables, they have a high impact on establishing the link on your BRI. Variable Endpoint type Connection Inband DTMF dialling Send Restart on Startup Description This is the most important setting. It defines whether your unit is a Network Terminal or Terminal Equipment. If you are connecting a BRI phone, set this to NT. If you are connecting to PSTN line, set this to TE. If you are connecting to a PBX, you will most likely have to try both to determine your PBX configuration (if unknown). *Usually* the PBX is TE and the Mediatrix unit the NT (PSTN replacement), but not always. Determine the type for the ISDN line to which you are connecting. Point-to- Multipoint is usually for phones, and Point-to-Point when connecting to a PBX or a PSTN line. Disable this variable if the inbound ISDN to SIP numbers have doubled digits, for example When using Point-to-Multipoint, set this variable to disable Page 9 of 24

10 You can apply the same configuration to all ports by clicking the BRI interfaces at the bottom. Validate the Interop Section When configuring a new unit or setup, set the variable in the Interop section to enable and select all ports before clicking Submit. When facing issues in call establishment, disable the variables one by one. Page 10 of 24

11 Configuring ISDN Services Configuration Notes 291 Enabling the Calling Line Information Presentation parameter makes the caller ID present in outgoing SIP to ISDN calls. WARNING: Even if the Mediatrix unit passes the caller ID, it could be suppressed further downstream on either SIP or ISDN. For caller ID problems, looking at the syslog messages containing the SEND Setup messages is a good debug approach. Setting the Facility Services to Enable enables the support of ISDN FACILITY messages. The MSN numbers fields allow configuring numbers that will be allowed when a call is incoming from the SIP side (in point-to multipoint configuration only). If the called party number is different from those three numbers, the call is silently discarded. Page 11 of 24

12 IP Synchronisation To synchronise a Mediatrix Master Synchronisation unit for video calls over ISDN, enter the IP address of the unit that acts as the synchronisation master. When the settings have been applied, synchronisation will start. It can take several hours before the unit is fully synchronised. The Unit Mode field displays the synchronisation status of the unit (Active/Inactive). SIP Configuration Registrar and Proxy 1. Enter the IP address or FQDN names of the Registrar and Proxy. Don t forget to specify the SIP port of the server (i.e. :5061) or use :0 if you wish to use the default port of If you use FQDN, using :0 will make the Mediatrix unit issue DNS SRV requests. 2. If you are using an Outbound Proxy, enter its IP address and port in the Outbound Proxy Host field. 3. Click Submit to save the data, or Submit & Refresh Registration to send new REGISTER packets to the Registrar. Page 12 of 24

13 Interop 1. In the SIP > Interop tab, set the following variables as defined below. If there are issues with the SIP INVITE messages, the SDP Interop variables may need to be modified. Page 13 of 24

14 Registration 1. In the SIP >Registration tab, configure the registrations required for your SIP UAs. 2. To configure a single SIP username per BRI port, set it in the corresponding User Name field, and set the corresponding Register field to Enable for the Endpoint. 3. To configure more than one username per BRI, add Unit Registration fields like the 103 user name in the above screenshot. 4. Click Submit. Page 14 of 24

15 Authentication 1. If your SIP user names require authentication, go to the SIP >Authentication tab to configure your user names and passwords. 2. If the user name applies to an endpoint (such as a BRI port), select Endpoint in the Apply To field. 3. If the user name was configured in a Unit Registration (see above section), select either unit or username. 4. If the registrations fails after the correct setup of the user name and password, set the Validate Realm variable to Enable and enter your realm in the Realm field. This can be determined by looking at the realm field in a 401 Unauthorized Sip response. In the screenshot below the realm is asterisk. Telephony and other VoIP Settings Page 15 of 24

16 Configuring the DTMF Maps The DTMF maps control which numbers can be dialled. This is also referred to as the Dial Plan. The default x.t allows dialing any digits, any number of times and then wait for the Inter DTMF Timeout. Configuring the Required CODECs Enable or disable the required codecs. The Data column, allows configuring the codecs used for faxes, modems and video calls. Note that you can set priorities for each CODEC. For example, the G.729 codec can be set as the preferred codec in SIP invites by setting a higher priority than the other enabled codecs. Click the Edit button next to the desired codec to set a Page 16 of 24

17 priority. The higher the priority number, the higher the codec priority in the SDP. In the following screenshots, G.711 has a higher priority than G.729. DTMF Transport Determines how the pressed digits (DTMFs) are transported on the network during a call. Parameter In-band Out of band using RTP (RFC 2833) Out of band using signalling protocol Description The DTMFs are transported in the audio stream directly (in the RTP packets). The Mediatrix unit sends special RTP packets that contain the DTMF information ( rtpevent filter in Wireshark). Important: RFC 2833 is negotiated in the initial SDP exchange. There are no rtpevent packets if the softswitch has RFC 2833 disabled. The Mediatrix unit sends SIP INFO packets. ( sip filter in Wireshark). By default, the Mediatrix unit uses the draft draftchoudhurisipinfodigit00. If DTMF fails to work, use the Mediatrix UMN software to change the following variable to infodtmfrelay. Page 17 of 24

18 Parameter Description Page 18 of 24

19 Ptime Modification for a Codec 1. Click the Edit button for the desired codec. 2. Change the packetisation time according to your softswitch settings. Page 19 of 24

20 Configuring the Call Router The Call Router defines the sources and destinations for all calls that pass through the Mediatrix unit. 1. Go to the Call Router Config section and add a new route by clicking on the + sign. Configuration Notes Avoid typing anything manually. Use the drop-down selector to select the route Source and Destination. For the first route, select isdn-bri1 as the source and sip-default as the destination, then click Submit. If several SIP gateways are configured, they will appear in the selector under sip-gatewayname. In the following screenshot the default SIP gateway is used. Page 20 of 24

21 3. Create a route for each BRI port. Please note that if a modification was made and the Config Modified is yellow, click the Apply button to apply the configuration. 4. Apply your changes. Adding a Hunt Group You can add a Hunt group if there are several BRI lines available for SIP to ISDN calls. The Hunt group enables the Mediatrix unit to cycle through all available BRI ports until a free B-channel is found. This can be useful for PSTN connection or PBX connections with multiple BRI ports. Page 21 of 24

22 Once this is done, add a normal route from sip-default as source to your hunt service. Page 22 of 24

23 Mapping for Video Conference Video conference equipment requires the use of the Unrestricted Digital transfer capability (ITC). 1. Under the Telephony > Codecs tab, make the following mapping: This means that for incoming INVITE messages using Clear Mode as first codec in the media list, the outgoing ISDN SETUP message will be of bearer unrestricted. It also means that for inbound SETUP messages of bearer capability unrestricted, the first codec in the outbound INVITE will be of type Clear Mode. 2. Adjust your desired codec accordingly. If you select Select instead of prioritize, your outgoing INVITE messages contain only the specified codec (in this screenshot Clear Mode). Restarting all Required Services By now a message should be displayed at the top of some web pages asking you to restart some services. 1. Click the hyperlink and the System > Services page comes up. 2. Find the services with a little * and select Restart in the corresponding Action drop-down menu. Page 23 of 24

24 3. You can click on the Services box at the top to refresh the status. Your Mediatrix unit should not be ready for operation. Management Configure Backup and Restore This section allows backing up and restoring the unit configuration. After the configuration of the unit, making a backup is recommended. 1. Enter a name for the file that will contain your backup and select your transfer protocol. The Location parameter is relative to the root directory. 2. Enter the hostname and use :0 when using the default protocol ports (69 for TFTP, 80 for HTTP, etc). 3. Click Submit to save the changes or Submit & Backup Now to export the file immediately.
