AUDIOCODES MP-104 GATEWAY INSTALLATION
This section describes how to install and configure the AudioCodes MP-104 gateway, shown
below.
The AudioCodes MP-104 FXO gateway supports up to four loop start line (FXO - foreign
exchange office) ports. Although the MP-104 is similar to the MP-100, each gateway uses a
different switch type for configuring the device. The MP-100 uses DIP switches, and the MP-
104 uses a command line switch (-fb) (see page 7). For details about command-line switches,
refer to the AudioCodes MP-1xx Media Gateway Fast Track Installation Guide.
The MP-104 on a v8.1 or later system with a v8.2.x or later firmware IPRC supports the peer-
to-peer (P2P) audio feature. This feature allows certain IP and SIP devices to transmit and
receive audio directly with each other. With this feature, the audio is not transmitted or
received through the system cabinet. This reduces delay and removes the audio stream from
the Time Division Mulitplex (TDM) highway.
To use P2P audio:
•The devices must be members of the same Network Group.
•The IPRC and IP devices must be upgraded to version 8.1 firmware. (SIP endpoints do
not require firmware upgrades.)
•The devices must terminate on an IPRC with v8.2.x or later firmware.
•There cannot be a NAT or firewall between the communicating devices.
•For SIP endpoints, the latest version of SIP Server (v1.1 or later) must be installed.
Because the devices are not using cabinet resources, devices connected in a P2P call cannot
use the following features:
•Agent Help
•Record-A-Call
•Station Monitor
The MP-104 on a v8.2.x or later IPRC firmware also does not support the following features:
•Tick Tone as an audio source for CO calls. This is normally used for features that
require audio sources, such as the Music-On-Hold feature.
•Pause digits. These digits are normally used to program a speed-dial or other digit
string.
NOTE: The MP-104 must be running software version 4.2 or later when connected to an IPRC
running version 8.1 or later firmware.

Quick Start Installation Outline
The following steps outline the MP-104 installation. For details, refer to the pages
shown in parentheses in each step.
To install the MP-104:
1. Unpack the box and check the parts list to make sure nothing is missing from the
shipment.
2. Set up the MP-104 gateway device through the AudioCodes BootP/TFTP Server
program (see page 4).
NOTE: Ensure you have added the -fb command to the ramMP1XXFXO.cmp
and this file is selected as the Boot file (see page 7)
3. Reset the Server. Progress can be viewed in the BootP/TFTP Server window
(make sure it is not paused). See page 9.
4. Configure the MP-104 application through the AudioCodes MP-104 Web
administrator (see page 19).
5. Verify that the Call Agent IP address in the Advanced Configuration - Protocol
Management page matches the IPRC IP address (see page 12).
6. Configure the IPRC ports through the IPRC Administrative Session Web page
and verify the following:
• The gateway is configured as an MGCP gateway and endpoint (the first cir-
cuit), and each additional endpoint is attached to the correct circuit (see
page 19).
• All information is correct (MAC address, IP address, etc.).
• The connection is active in the Circuit Status page.
The AudioCodes MP-104 Gateway is now ready for connection to the CO.

Setting Up the MP-104
Follow the instructions below to set up the MP-104.
To set up the MP-104:
1. Attach the Ethernet cable to the ETH-1 RJ-45 connector to connect to your LAN.
2. Plug in the AC power cord and connect the DC power supply. The green lamps on the
LAN and Ready light-emitting diodes (LEDs) light. For details on LED indicators, refer
to the MP-104 User’s Manual & Installation Guide. The back view of an MP-104 is
shown below.
3. Attach up to four phone lines (e.g., loop start lines) to the RJ-11 connectors.
NOTE: Up to 200 m (660 ft) of 24AWG twisted pair cable can be used for phone lines.
4. Create a new directory (e.g., Audiocodes MP_104) in the Windows Explorer on the PC
that is connected to the MP-104.
NOTE: Make sure the MP-104 and BootP/TFTP Server are on the same submit
because the BootP/TFTP Server does not work across subnets.
5. Unzip the MP104v44 zip file (part no. 841.0165) that is provided in the Inter-Tel IP
Devices CD into this folder.
6. You may want to create a subfolder for the BootP zip file within the same folder, and
unzip the BootP zip file into this folder. The folder looks like the one shown below.
WARNING
DO NOT use the manufacturer-provided CD-ROM that contains generic downloading files
and the Media Pack MP-1xx Media Gateway Fast Track Installation Guide. For the Audio-
Codes MP-100/104 Gateway to work properly with the Inter-Tel Axxess system, you must
use the customized downloading files and the quick start guide that are provided on the
Inter-Tel IP Devices CD-ROM (part number 827.9162). Using the manufacturer-provided
files may cause application errors, and the system may not work properly.

7. Copy the following files that you just unzipped and paste them into the BootP server
folder (under C:\Program Files\AudioCodes\BootP). This will allow the system to find
the required files automatically.
NOTE: The file names may be different depending on the version and date that the
files are created.
ALSO: The_usa files are for US systems, and the_uk files are for European systems.
• BOOT file (e.g., ramMP10X.cmp) — Contains a compressed, downloadable soft-
ware image file.
• INI file (e.g., MP1XXFXO_usa/uk.ini) — Contains the default settings for the
MP-104.
• Coefficient file (e.g., MP1xx12-1-12khz-fxo_usa.dat or MP1xx10-2-
16khz-TBR21-fxo_uk.dat) — Contains a set of parameters for the signal
processor of the loop interface devices.
• Call Progress Tone file (e.g., call_progress_usa/uk.dat) — Contains the
definitions of the call progress tones that the MP-104 will detect/generate.
8. Open the MP1XXFXO_usa/uk.ini file by using a word processor, such as Notepad,
Microsoft®Word, etc. and add the following settings:
• The MP-104 needs to communicate with an IPRC. Determine the IPRC that you
are going to use and enter the IPRC IP address (e.g., 10.1.1.50) in the CallAgentIP
field, as shown below.
NOTE: Programming the IPRC IP address in the .ini file provides a more reliable
Call Agent ID setting for the MP-104, when files are loaded via the TFTP server. If
not modified in the .ini file, this value is overwritten every time the MP-104 files are
reloaded during a reset, using the value in this file. If the .ini file is “read only” by
default, you may need to modify this characteristic to allow updating. To change the
attributes, right-click the file name in the Windows Explorer and open Properties.
Uncheck Read-only in the Attributes field and click OK.
• Enter the endpoint name in the EndpointName field and the gateway name in the
GateWayName field, if necessary. The default values are set to “ACgw” and
“MP104,” respectively. These values must match those in Axxess Database Pro-
gramming (under System\Devices and Feature Codes\Trunks) and in the Audio-
Codes Web administrator (see page 11).
