Requirement for analog phone at remote branch office. Toll-Bypass for intra-office calls. 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: Mediatrix 1104 SIP Reference Manual (SIP v5.0 version).
CD included with the unit. 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 PC , proceed with the following steps.

0230 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.

– not DHCP) to avoid restarting the computer or stopping and restarting the UMN service whenever you change the IP address and subnet of the Mediatrix unit. This is recommended for advanced IP network users, the current configuration notes do not cover the step by step setting for this alternative.
Restart the unit after the configuration of IP addresses for the unit to accept the new addresses. When using DHCP: you can also reserve the IP address for the Mediatrix 1104 by assigning the MAC address of the unit to a specific IP address in your DHCP server – it will be easier to auto-detect the unit for provisioning. An example of a unit IP address fetched by DHCP is shown in the figure below.

Mediatrix 1104 port. Each port on the 1104 requires a User Name. Using this setup will route all calls from the Mediatrix 1104 to the assigned IP address, that is our Mediatrix 1204. Note that you cannot use this configuration to route calls to more than one unit.

Set the Port Behaviour On the top menu bar, check the option Automatic GET. Go to iso>org>dod>internet>private>enterprises>mediatrix > mediatrixExperimental > sipExperimentalMIB > sipExperimentalMIBObjects > sipUnregisteredPortBehavior and set this parameter to enableport in the drop down menu that appears upon double-clicking the value located in the upper-right pane.

Go to mediatrix > mediatrixExperimental > sipExperimentalMIB > sipExperimentalMIBObjects > sipNatCustom > sipNatCustomPublicAddress and set the parameter to be the public IP address of the NAT/Firewall router where the Mediatrix 1104 is located. In this scenario, the IP address would be 69.129.134.6 as shown in the following figure.

Step 7: Configure the Hook Flash Relay If your PBX uses the Hook Flash feature, you must configure both the Mediatrix 1104 and Mediatrix 1204 so that they can properly exchange the Hook Flash events. See also the Mediatrix 1204 configuration.
Restart the unit after the configuration of IP addresses for the unit to accept the new addresses. When using DHCP, you can reserve the IP address for the Mediatrix 1204 by assigning the MAC address of the unit to a specific IP address in your DHCP server – it will be easier to auto-detect the unit for provisioning.

1204 and set the following: Uncheck DHCP. Set the SIP Proxy field to be the IP address of the destination devices, the Mediatrix 1104 IP address in this case. Use default values for the other entries. Page 13 of 23...

Configure Incoming Calls from PSTN Behaviour The Mediatrix 1204 exhibits two possible behaviours when an incoming call from the PSTN is received: The Mediatrix 1204 goes off-hook and produces a second dial tone from which the PSTN user can dial a number in IP.

Step 4: NAT Traversal Configuration You must configure the following parameters for the Mediatrix unit to work behind a NAT/Firewall router: Go to mediatrix > mediatrixExperimental > sipExperimentalMIB > sipExperimentalMIBObjects > sipNatCustom > sipNatCustomEnable and set this parameter to enable.

Configure Dial Tone Detection The FXO dial tone detection mechanim allows the Mediatrix 1204 to wait for a dial tone on the PSTN side before initiating the dialing sequence. If no dial tone is detected, the line is considered busy with an incoming PSTN call. This mechanism helps to avoid collisions between incoming and outgoing calls.

PBX extension. Note: If the PBX does not pass the caller ID to the Mediatrix 1204, you can reduce the <fxoPreAnswerDelay = 1000> to reduce the time before the Mediatrix 1204 goes off-hook upon ring detection.

Set the lineSelectionDigitMap variable to the number corresponding to the Mediatrix 1104 FXS user name. This feature enables the port-to-port mapping between the Mediatrix 1104 and Mediatrix 1204. Each port of the Mediatrix 1204 corresponds to a specific port of the Mediatrix 1104.

Ground Start lines were created. If the far end disconnect signal is not sent to or properly detected by the Mediatrix 1204, the connection will not be released by the unit, thus freezing the FXO port in the off hook state.

0230 Set the frequency that the Mediatrix 1204 needs to detect for far end disconnect. This frequency is typically the dial tone frequency (350 Hz for North America) but will vary from one PBX to another. Please verify with your PBX vendor to determine what tone (exact frequency and cadence) the PBX produces on the extension when the far end is disconnected.

Step 10: Configure the Hook Flash Relay If your PBX uses the Hook Flash feature, you must configure both the Mediatrix 1104 and Mediatrix 1204 so that they can properly exchange the Hook Flash events. See also the Mediatrix 1104 configuration.

Go to mediatrix > mediatrixConfig > fxoMIB > fxoMIBObjects > fxoIfAnsweringDelayTable > fxoIfAnsweringDelayEntry > fxoWaitForCalleeToAnswerEnable and set it to enable. This instructs the Mediatrix 1204 to wait until the called party answers the phone before it picks up the PSTN line. Step 11: Make a Call Connect an analog phone to a port of your Mediatrix 1104 device.
Enabling Current Drop on your PBX extensions connected to the Mediatrix 1204 will improve the release line. No dial tone on the Mediatrix 1104 when picking up the phone. Verify the configuration of your Mediatrix 1104 or your hardware connection on the Mediatrix 1104. The problem would reside on the Mediatrix 1104’s since it provides dial tone to its ports.
