This article describes the setup of the AlphaCom E system and the AudioCodes Mediant 1000 Gateway. The Mediant 1000 supports mixed digital and analog interface configurations, providing up to four E1/T1/J1 spans and up to 24 analog interfaces in various FXO/FXS configurations. Although this article describes the configuration for digital interface E1 using QSIG protocol, it will also be useful when configuring the Mediant 1000 for analog FXO/FXS or ISDN lines.
This article describes the configuration for digital interface, and covers the most common features used in an AlphaCom E/AudioCodes interconnection.

=== AlphaWeb Configuration ===
 
==== Assign IP address to the AlphaCom E Ethernet port(s) ====
 
Log on to AlphaWeb and enter a valid IP address on the Ethernet port.
 
In the example below, Ethernet port 1 is used.
 
Consult your network administrator to obtain the IP address.

<br>
 
<br>
 
<br>
 
 
 
The SIP Trunk IP address must be identical to the IP address of the SIP
 
Gateway.
 
 
 
'''Note:''' If the AlphaCom is configured with a SIP Registar node in addition to the
 
SIP Trunk node, the SIP Registar node must have a lower node number
 
than the SIP Trunk node.
 
 
 
==== Create AlphaCom/SIP Audion links ====
 
''This paragraph is only relevant for AMC software 10.04 or earlier.''
 
 
 
From AMC 10.05 the audio links are assigned dynamically whenever
 
needed, and there is no need to specify the links in AlphaPro. Proceed
 
[http://10.5.2.54/wiki/index.php/Configuration_guide_for_AudioCodes_MP114/118#Define_the_AlphaCom_.2F_SIP_routing Define the AlphaCom / SIP routing].
 
 
 
However, if you want to reserve VoIP channels for the SIP Gateway,
 
you can do so by following the description below.
 
 
 
In '''Exchange & System > NetAudio''' use the ''Insert'' button to create one
 
or several audio (VoIP) links between the AlphaCom and the SIP
 
Gateway.
 
The physical number specifies the VoIP channel and must be in the
 
range 605 – 634 (start with 605). Normally the number of audio links will
 
be equal to the number of phone lines connected to the SIP Gateway.

==== Define the AlphaCom / SIP routing ====
 
In '''Exchange & System > Net Routing''' use the ''Insert'' button to create a
 
route between the AlphaCom and SIP Gateway. Set '''Preferred codec'''
 
to ''G711u'' and '''RTP Packet Size''' to ''10 ms''.

==== Create Prefix number ====
 
The directory number (prefix) used to access the telephone line must be
 
programmed in the AlphaCom directory table with ''feature'' 83 and '''Node'''
 
= SIP Trunk node number (100 in this example). In the example below
 
the default directory number 0 has been modified to be used as a prefix.

In the example below all four FXO lines belong to Hunt Group ID 1.
 
When dialing 0 on a station the first available line will be granted.
 
Directory number 0 must be programmed in the '''AlphaCom directory

If there are unused lines, leave the fields for that line blank.
 
 
 
==== FXO Line Select ====
 
In installations with different types of equipment connected to the
 
various FXO lines the user must be able to select which FXO port to
 
use. On a ship, for instance, there could be a mix of shore lines, GSM
 
interface and SatCom lines. Line selection is achieved by assigning
 
each port a '''Phone Number''' in the '''Endpoint Phone Number Table'''.
 
These directory numbers must be programmed in the AlphaCom
 
'''directory table''' ''with feature 83/<node>''. See [http://10.5.2.54/wiki/index.php/Configuration_guide_for_AudioCodes_MP114/118#Create_Prefix_number Create Prefix Number]

* Selective Dialing
 
* Automatic Dialing
 
* Delayed Automatic Dialing
 
 
 
==== Selective Dialing ====
 
A second dial tone will be presented when calling in, and the user can
 
dial the desired intercom number. The fields in the '''Automatic Dialing'''
 
table must be left blank (Default setting).
 
('''Protocol Management > Endpoint Settings > Automatic Dialing''').

In this mode the gateway collects digits from the line, and sets up the
 
call towards the AlphaCom when a predefined number of digits are
 
collected and no more digits are received within a preset time (default 4
 
seconds), or when the ‘#’ key is dialed.
 
 
 
In '''Protocol Management > Protocol Definition > DTMF & Dialing'',
 
set '''Max Digits In Phone Num''' equal to the number of digits used on the
 
AlphaCom stations, normally 3 or 4. The parameter '''Inter Digit Timeout'''
 
specifies the waiting time for more digits before setting up the call.

<br>
 
 
 
==== Automatic Dialing (Call to Switchboard) ====
 
When calling in, the call will automatically be connected to a predefined
 
intercom number.
 
 
 
Enter the intercom number in the '''Destination Phone Number field''' in
 
the '''Automatic Dialing''' table. Set '''Auto Dial Status''' to Enable.
 
'''(Protocol Management > Endpoint Settings > Automatic Dialing)'''.

In the example above, calls on line 1, 3 and 4 are routed to station 103,
 
and incoming calls on line 2 are routed to station 101.
 
 
 
==== Delayed Automatic Dialing ( Delayed Call to Switchboard) ====
 
If '''Auto Dial Status''' is set to ''Hotline'', a second dial tone will be
 
presented when calling in, allowing the user to dial a number. But if no
 
digits are pressed within the '''Hotline Dial Tone Duration''' time, the
 
number in the '''Destination Phone Number''' is automatically dialed.

<br>
 
<br>
 
<br>

<br>
 
 
 
The '''Hotline Dial Tone Duration''' can be changed. The default value is
 
16 seconds. ('''Protocol Management > Protocol Definition > DTMF &
 
Dialing > Hotline Dial Tone Duration'''').
 
 
 
==== Caller ID ====
 
Use the '''Caller Display Information''' table to send display information to
 
the intercom station that receives the call. ('''Protocol Management >
 
Endpoint Settings > Caller ID''').

The prefix code entered in the '''End Point Phone Number Table''' will be
 
shown together with the text in '''Caller ID/Name'''.
 
 
 
If Caller ID name is detected on the FXO line, this will be used instead
 
of the Caller ID name in the table above. Caller ID from FXO line must
 
be enabled in '''Protocol Management > Advanced Parameters >
 
Supplementary Services'''.
 
 
 
Set '''Enable Caller ID''' to Enable and choose the CID protocol used by
 
the PSTN supplier in '''Caller ID Type'''.
 
Check with the local telephone company to find the CID protocol used.

== Far End Disconnect (FED) ==
 
Far End Disconnect refers to methods for detecting that a remote party
 
has hung up. The far end disconnect signal is not mandatory and this
 
could create problems. If the Far End Disconnect signal is not sent to or
 
properly detected by the SIP Gateway, the connection will not be
 
released by the unit, thus freezing the FXO line in the off hook state.
 
 
 
=== Call Termination options in the SIP Gateway ===
 
The following methods for call termination are supported by the
 
AudioCodes Mediant 1000. Note that the used disconnection methods
 
must be supported by the CO (Central Office) or to PBX (Private Branch
 
Exchange).
 
 
 
* Detection of polarity reversal / current disconnect
 
* Detection of Busy / Dial tones
 
* Detection of silence
 
* Timeout of Conversation
 
 
 
==== Detection of polarity reversal / current disconnect ====
 
This is the recommended method. The call is immediately disconnected
 
after polarity reversal or current disconnect is detected on the Tel side
 
(assuming the PBX / CO produces this signal).
 
 
 
Open the General Parameters screen ('''Protocol Management >
 
Advanced Parameters > General Parameters''') and enable the
 
relevant detection method.

<br>
 
<br>
 
<br>
 
<br>
 
<br>
 
 
 
==== Detection of Busy / Dial tones ====
 
The call is immediately disconnected after Busy or Dial tone is detected
 
on the Tel side (assuming the PBX / CO produces this tone). This
 
method requires the correct tone frequencies and cadence to be defined
 
in the Call Progress Tones (CPT) file of the SIP Gateway. If these
 
frequencies are not known, define them in the CPT file (the tone
 
produced by the PBX / CO must be recorded and its frequencies
 
analyzed). This method is slightly less reliable than the previous one.
 
 
 
A file with the most common tone patterns can be downloaded from
 
http://www.zenitel.com/stentofon/support.
 
 
 
Open the '''FXO Settings''' screen ('''Protocol Management > FXO Settings > FXO Settings''') and enable the relevant detection method.

<u>'''''Call Progress Tones (CPT)'''''</u>
 
The Detection of Busy / Dial tones method requires the correct tone
 
frequencies and cadence (on/off sequence) to be defined in the Call
 
Progress Tones (CPT) file of the SIP gateway. These tones are region
 
specific and telephone exchange dependent.
 
 
 
The Call Progress Tones (CPT) configuration file is a binary file (with the
 
extension '''.dat''').
 
 
 
Users can either use one of the supplied configuration (dat) files found
 
on the CD provided with the gateway, or construct their own file.
 
 
 
Either:
 
* Modify the supplied usa_tone.ini file (in any standard text editor) to suit the specific requirements, and convert the modified ini file into binary format using the '''TrunkPack Downloadable Conversion Utility'''.
 
Or:
 
* Use the Call Progress Tones Wizard.
 
The '''Call Progress Tones Wizard''' (CPTWizard) is an application
 
designed to detect the Call Progress Tones generated by your PBX (or
 
telephone exchange) to create a basic Call Progress Tones ''ini'' file
 
containing definitions for all relevant Call Progress Tones. This provides
 
a good starting point when configuring the SIP gateway. This ''ini'' file can
 
then be converted to a ''dat'' file using the '''TrunkPack Downloadable
 
Conversion utility'''.
 
 
 
Both the '''TrunkPack Downloadable Conversion Utility'''
 
(''DConvert.exe'') and the '''Call Progress Tones Wizard''' (''CPTWizard.exe'')
 
are provided with the AudioCodes CD.
 
 
 
Load a Call Progress Tones (''dat'') file to the SIP gateway:
 
 
 
* Open the Regional Settings screen ('''Advanced Configuration > Regional Settings''').

* Click the Browse button and navigate to the folder that contains the file you want to load
 
* Click the file and click the Open button; the name and path of the file appear in the field beside the Browse button
 
* Click the Send File button
 
* Save configuration so the file can be available after a power failure
 
* Reset the SIP Gateway for the changes to take effect
 
 
 
For more detailed information regarding Call Progress Tones please
 
refer to the following sections in the AudioCodes ‘LTRT-65406
 
MediaPack SIP User's Manual Ver 4.8’ on the CD supplied with the unit:
 
 
 
* Section 15.1 – on how to configure the CPT ini file
 
* Section D.1.1 – on how to convert CPT ini file to a binary dat file
 
* Section D.2 – on how to use the Call Progress Tones Wizard (CPTWizard) application
 
 
 
==== Detection of Silence ====
 
The call is disconnected after silence is detected on both call directions
 
for a specific (configurable) amount of time. This method should only be
 
used as a backup.
 
 
 
Open the '''General Parameters screen (Protocol Management >
 
Advanced Parameters > General Parameters''').

<br>
 
 
 
==== Timeout of Conversation ====
 
As an additional safety to prevent lines from accidentally locking up, it is
 
recommended to enable a timeout of conversation.
 
 
 
The '''Max Call Duration''' defines the maximum call duration in minutes. If
 
this time expires, both sides of the call are released (IP and Tel). The
 
valid range is 0 to 120. The default is 0 (no limitation). ('''Protocol
 
Management > Advanced Parameters > General Parameters: Max
 
Call Duration''').

== Miscellaneous Features ==
 
[[image:Configuration guide for AudioCodes MP114 118 - Incoming Calls in Private.jpg|thumb|left|250px|]]
 
=== Incoming Calls in Private ===
 
Incoming calls from the telephone line can be forced to be in private
 
ringing mode, independent of the private/open switch of the intercom
 
station (''from AlphaPro/AMC 10.05'').
 
 
 
Check the flag '''Private Ringing from SIP''' in AlphaPro, ('''Exchange &
 
System > System > Calls and Options''').
 
 
 
=== Door Opening Feature ===
 
During a conversation between a door station and a telephone, the
 
telephone operator can activate the ''Door Opening'' feature in the
 
AlphaCom by pressing digit 6.
 
 
 
==== SIP Gateway Feature ====
 
To enable digit actions from the telephone line during conversation, set
 
'''1st Tx DTMF Option''' to INFO(Cisco) in '''Protocol Management >
 
Protocol Definition > DTMF & Dialing'''.

==== AlphaCom configuration ====
 
[[image:Configuration guide for AudioCodes MP114 118 - AlphaCom configuration.jpg|thumb|left|250px|]]
 
The Door Opening feature is programmed in the Event Handler. There
 
are two separate events for the door opening feature, depending on who
 
is the calling side:
 
 
 
* calling from the telephone to the door
 
* calling from the door to the telephone
 
 
 
<u>'''''Calling from the telephone to the door''''</u>
 
The Standard door opening event is used.
 
 
 
[[image:Configuration guide for AudioCodes MP114 118 - AlphaCom configuration (2).jpg|thumb|left|250px|]]
 
<u>'''''Calling from the door to the telephone:'''''</u>
 
 
 
When the phone presses digit 6, the event type '''Event Trigger Feature'''
 
(15) is reported, with the digit 6 as sub event. The calling AlphaCom
 
station is Event Owner, and called SIP phone number and node number
 
is Related To. The RCO pulse time is specified as an additional
 
parameter in the RCO action string, i.e. RCO 3 ON 20 means pulse
 
RCO 3 for 2 seconds.
 
 
 
=== M-key Control from Telephone Network ===
 
The ‘*’ and ‘#’ buttons on the telephone can be used to control M-key
 
function (simplex audio) ON or OFF:
 
 
 
* Press the ‘*’-key briefly and the M-key is turned ON
 
* Press the ‘#’-key briefly and the M-key is turned OFF
 
 
 
This can be useful for group call announcement from the telephone.
 
The feature is enabled by setting '''1st Tx DTMF Option''' to ''INFO(Cisco)'' in
 
'''Protocol Management > Protocol Definition > DTMF & Dialing'''.
 
 
 
=== Transmit ‘*’ and ‘#’ from AlphaCom ===
 
The DTMF signals ‘*’ and ‘#’ will be transmitted to the line when DAK 0
 
(*) and DAK 1 (#) is pressed during a telephone conversation. (No
 
programming is required).
 
 
 
=== Voice Switching in Noisy Environment ===
 
If the intercom station is located in a noisy environment, it might be
 
difficult to switch the voice direction from the telephone towards the
 
intercom station. However, there is a setting in the AlphaCom (from
 
AMC 10.05) to overcome this problem. Use the nvram editor in the TST
 
Console to set the parameter:
 
 
 
.ex_profile.flags.DSP_duplex = 1
 
 
 
Contact your local STENTOFON dealer for TST programming help.
 
 
 
When this flag is set, the initial voice direction is forced to be from the
 
intercom towards the telephone. When the phone operator starts to
 
speak, the voice direction will switch towards the intercom station,
 
regardless of the level of the audio signal from the intercom station. As
 
soon as the phone operator stops speaking, the voice direction will
 
switch back to the initial direction.
 
 
 
Make sure that the ''Echo Canceler'' is enabled in the SIP Gateway.
 
'''(Protocol Management > Profile Definitions > Tel Profile Settings >
 
Echo Canceler = Enable)'''
 
 
 
=== Country Settings ===
 
The Line Characteristics (AC impedance matching, hybrid balance, Tx &
 
Rx frequency response, Tx & Rx Gains, ring detection threshold, DC
 
characteristics) should be set according to country of origin.
 
 
 
Some of the SIP Gateway parameters are configurable through the ''ini''
 
configuration file only (and not via the Web). The '''CountryCoefficients'''
 
parameter that determines the line characteristics must be configured
 
via the ''ini'' configuration file.
 
 
 
Procedure to modify the ''ini'' file:
 
 
 
* Get the ''ini'' file from the gateway using the Embedded Web Server
 
('''Advanced Configuration > Configuration File > Get ''ini'' File)''':
 
 
 
[[image:Configuration guide for AudioCodes MP114 118 - Country Settings.jpg|thumb|left|250px|]]
 
<br>
 
<br>
 
<br>
 
<br>
 
<br>
 
<br>
 
<br>
 
<br>
 
<br>
 
<br>
 
 
 
* Open the file (the file is open in Notepad or a Customer-defined text
 
file editor) and add anywhere in the file the line
 
 
 
CountryCoefficients = xx
 
* where xx is the country code found below; save and close the file.
 
The example shows the settings for Norway (46).
 
 
 
[[image:Configuration guide for AudioCodes MP114 118 - Country Settings (2).jpg|thumb|left|250px|]]
 
 
 
* Load the modified ''ini'' file back to the gateway (using the '''Send ''ini''
 
File''').
 
 
 
This method preserves the programming that already exists in the
 
device, including special default values that were preconfigured when
 
the unit was manufactured.

This article describes the setup of the AlphaCom E system and the AudioCodes Mediant 1000 Gateway. The Mediant 1000 supports mixed digital and analog interface configurations, providing up to four E1/T1/J1 spans and up to 24 analog interfaces in various FXO/FXS configurations. Although this article describes the configuration for digital interface E1 using QSIG protocol, it will also be useful when configuring the Mediant 1000 for analog FXO/FXS or ISDN lines.

Configuration example

AlphaCom Configuration

How to set up a SIP Trunk in the AlphaCom is described here: SIP trunk node - configuration

AudioCodes Mediant 1000 Configuration

Configure Network Parameters

The AudioCodes Mediant 1000 VoIP Gateway comes with default network parameters (factory default parameters).

Before you can set up the gateway in the network, you have to change the default IP address to a fixed IP address in your network environment. The unit is configured from a web browser, e.g. Internet Explorer or Firefox. Consult the network administrator to get the correct IP address.

Follow these steps:

  • Load factory network parameters and reset the username and password to its default settings (username: Admin, password: Admin) by pressing the reset button located to the right of ethernet port II, and directly above the RS-232 port, labeled // for minimum 6 seconds.
    • The VoIP Gateway will now get the IP address 192.168.0.2, submask 255.255.255.0.
  • Change the IP address of your PC to 192.168.0.10, submask 255.255.255.0.
  • Connect the LAN port of the PC to the Ethernet port I of the VoIP Gateway. Use a crossed cable or connect the PC and the VoIP Gateway to a common switch using straight cables.
PC connected for management


  • Start your Web Browser and type 'http://192.168.0.2' in the URL field. A log-in window appear, type in user name Admin and password Admin. (Case-sensitive!). Now the ‘Quick Setup’ screen opens.
Quick Setup menu - Mediant 1000


IP Configuration
Enter the IP Address and Subnet Mask of the AudioCodes Gateway. This IP address must be identical to the IP address of the SIP Trunk Node created in AlphaPro.


SIP Parameters
Set Working with Proxy to Yes. Enter the IP address of the AlphaCom in the Proxy IP Address field. Set Enable Registration to Disable. Leave Gateway Name and Proxy Name blank.


  • Click Reset button and OK button to apply the changes.
  • Disconnect the PC from the Gateway.
  • Reconnect the Ethernet port I of the VoIP Gateway to the LAN
  • Reconnect the PC to the LAN.
  • Restore the PC’s IP address and subnet mask to what they originally were, and re-access the Gateway using the new assigned IP address.

Audio Codec

Audio Codec settings


In the Quick Setup screen, select Coders Table. Choose G.711U-law codec, 10 ms packet size and silence suppression Disabled.

  • Press Submit to save changes.


About Saving Changes

The Submit button will save the data to the running volatile memory. The changes take effect on-the-fly. The changes will not survive hardware reset or power off.

To permanently save the configuration data you need to store the data to flash memory by selecting Maintenance from the main menu. Click the BURN button. A confirmation message appears when the save is completed successfully.

Note: Parameters proceeded by an exclamation mark (!) is not changeable on-the-fly and require that the device is reset.

Backup and Restore

The configuration of the AudioCodes Gateway can be stored to a file on your PC. Use the Configuration File menu to store or restore the configuration (Advanced Configuration > Configuration File).

AlphaCom to Telephone Network

Trunk Settings

In Advanced Configuration > Trunk Settings you specify the properties of the trunk line. Select the protocol to be used for the trunk (Protocol Type), the trunk clock source (Clock Master), Line Code and physical framing to be used (Framing Method), and other relevant parameters.

Mediant 1000 - Trunk Settings


Define a Trunk Group

In Protocol Management > Trunk Group you specify which channels to use on the E1 trunk, and assign the trunk to a Trunk Group ID and a Profile ID:

Mediant 1000 - Trunk Group Table


Trunk Group Settings

In Protocol Management > Trunk Group Settings you assign the rules for channel allocation:

Mediant 1000 - Trunk Group settings


IP to Trunk Group routing

In Protocol Management > Routing Tables > IP to Hunt Group Routing you specify the Trunk Group ID to use for call from IP (i.e. calls from AlphaCom E). In the example below all calls from AlphaCom are routed to Trunk Group 1.

IP to Trunk Group Routing Table


Telephone Network to AlphaCom

Because the AlphaCom is defined as a Proxy Server in the SIP Gateway, you do not need to configure any Tel to IP Routing. The calling telephone number is automatically forwarded to the Proxy Server (i.e. the AlphaCom).
