1 Important Notes
Check the SIP 3rd Party Validation Website for current validation status.
SIP 3rd Part Validation Website can be viewed at:
 or
It is recommended to make basic changes to the I3 supplied .ini file then
utilize the web interface for further configuration.
As this unit is a critical piece of the SIP infrastructure, it is highly
recommended that DHCP not be used. A static IP address is the preferred
method and is how the unit was configured during validation.
After a factory reset, the Mediant 2000 will default to G.729 as its primary
The option for clock master is not exposed in the web interface. The settings
in the I3 supplied .ini file are to derive clock from the PSTN connection.
Should the internal oscillator be required, refer to INI Parameters Section of
this document, specifically the TDMBusClockSource, ClockMaster and
ClockMaster_x parameters.
When using SRTP the number of available E1 channels is decreased. See
Security section 8 below.
2 Vendor Documentation
Documentation can be found on the CD shipped with the Mediant 2000.
3 Validated Firmware Version
V 6.00A.020.002
4 Install
Download the Mediant 2000 files from the Interactive Intelligence Testlab
website for the M2K:
Contained in the zip file will be the validated version of firmware (.cmp), as
well as any supplemental configuration files, and a sample .ini file.
5 Configuration
 Manipulation of the supplied .ini file, then uploading it via the web interface. This method
is recommended for a quick start scenario. The I3 supplied .ini file, with just a few
modifications will get a basic setup up and running. Please note, the I3 supplied .ini file is
not meant to be a drop in configuration for every environment, it is provided as reference
 Web interface. (This method was used to configure the unit during validation) There are
many advanced options that are exposed in the web interface. Caution should be
exercised and the Audiocodes documentation should always be referenced when using
the web interface configuration option.
 TFTP. This has not been tested.
Initial Setup:
 Unzip the ZIP file containing the Mediant 2000 configuration files and firmware.
 Follow the AudioCodes instructions (on the CD or in the booklet shipped with the Mediant
2000 or in) for getting an IP address assigned to the MP box.
 Modify the I3 provided .ini file as appropriate.
 Start a web browser and type in the IP address of the Mediant 2000.
 The default user name is “Admin” (with a capital “A”) and the password is “Admin” (with a
capital “A”). It is recommended to change the password at this time for security reasons.
 In Interaction Administrator, the line that is configured for the gateway should have
“Terminate Analysis on Connect” checked.
Download Current Firmware (CMP file):
 From the main web screen, select Software Update from the icons on the left side of the
 Depending on what version of firmware is currently running on the Mediant 2000, two
options will be available, “Software File-Download” or “Software Upgrade Wizard”
 Choose the appropriate option and load the validated version of firmware onto the
Mediant 2000.
 After the validated firmware has been applied the Mediant 2000 will restart. Once the
restart is complete, return to the web interface and click on “Status & Diagnostics” on the
left hand side of the screen. Then select “System Information” from the top of the screen.
The displayed Version ID should match the firmware version as noted in section 1.1.3. If
it does not, double check the upgrade steps and consult the Audiocodes documentation if
Download Auxiliary File(s):
 From the Software Update Section, select “Load Auxiliary Files”
 Click the browse button to select the auxiliary file to download, then click “Send File.”
 During the validation procedure, the only auxiliary file option tested was the E&M Wink
CAS file for T1 signaling.
 Repeat the steps in this section any additional auxiliary files required for this installation.
Changing the Configuration:
 Prior to making any changes, the Audiocodes documentation should be consulted for
information on configuration parameters, options and functions.
 Changes can be made via the web interface or the .ini file can be modified and redownloaded to the Mediant 2000.
Description of more significant .ini parameters. This is not a comprehensive list of all
parameters found in the .ini file. A bold face parameter name indicates that it should be
changed to represent specific site information.
Sets the 4 TOS layer 3 bits.
Values: 0 through 15
Example: IPTOS = 0
Specifies transport mechanism for DTMF tones
0 (erase digits and do not relay)

2 (digits remain in voice stream – inband)
3 (erase digits and relay using RFC2833)
Example: DTMFTransportType = 3
Payload number to use for RFC2833 packets. This
value is only used when DTMFTransportType = 3.
Values: 96-99, 105-127
Which coders should be used. Each coder will be
on its own line. Up to 5 can be given. The first
one specified is given precedence.
Note: This line can be specified multiple times.

Table is used.

6 Redundant Proxy Configuration
The following configuration options are found under Protocol
Management/Protocol Definition/Proxy & Registration in the web interface. In
order for the Mediant 2000 to function with redundant proxies, the following
value must be set:
Proxy IP Address
First Redundant Proxy IP Address
Redundancy Mode
IP Address of the primary proxy.
IP Address of the secondary proxy.
Values: Homing, Parking
Homing: Gateway will ALWAYS try the primary
proxy on every call attempt.
Enable Proxy Keep Alive
Parking: Gateway will “park” on the last known
good proxy until that proxy fails.
Value: Using Options
Enable Proxy Hot-Swap
Gateway will sent OPTIONS messages to verify a
proxy is online.
Value: Enabled
Gateway will attempt proxy failover if this is not
The following parameters are optional and enable advanced failover
Enable Fallback to Routing Table
If none of the configured proxies are available, the
gateway will attempt to deliver the call based upon
its internal routing Tel to IP routing table.
How often (in seconds) the OPTIONS messagew will
be sent to verify a proxy is online.
How many re-transmits before failover takes place.
Proxy Keep Alive Time
Number of RTX Before Hot-Swap
7 Putback Transfer
Select the Call Putback checkbox for the SIP line to enable the ability for the
IC system to receive a call from the PSTN or a PBX, perform some processing
on the call and then transfer the call to a non-IC destination (a PBX station or
a remote number), without tying up two IC SIP trunks (one for the original
call and one for the call to the destination). By default this setting is
8 Security
StrongEncryption must be enabled
The Mediant requires a feature key with “StrongEncryption” enabled in order
to support the required cipher suites. StrongEncryption may not be enabled
by default. To check, follow these steps:
Select Software Update from the left menu. Choose Software Upgrade Key
from the top, view the Key features, and verify:
Security: IPSEC MediaEncryption StrongEncryption EncryptControlProtocol
If “StrongEncryption” is shown, then it is enabled.
SRTP Settings
Enable Media Security
Enables or disables the Secure Real-Time Transport Protocol (SRTP).
0 = SRTP is disabled (default).
1 = SRTP is enabled.
Note 1: SRTP is available only if DSPVersionTemplateNumber = 0 or 2.
Note 2: Use of SRTP reduces the number of available channels.
TP-1610, Mediant 2000, TP-260:
Template 0, 200 channels are available (per TPM).
Template 2, 120 channels are available (per TPM).
A TPM is up to 8 spans. Refer to the 6.00A User manual, Overview section 1.4.
For DSP=0:
4 span = 200 SRTP lines
8 span = 200 SRTP lines
16 span = 400 SRTP lines
For DSP=2
4 span = 120 SRTP lines
8 span = 120 SRTP lines
16 span = 240 SRTP lines
To check the Mediant DSP Version, select Status & Diagnostics on the left,
and Device Information from the top. Under Versions, view DSP Type.
For the rest of the TLS/SRTP configuration refer to either the 6.00A User manual
or the Interactive Intelligence document:
