The web interface of the ICX-500 Gateway

This article describes the web interface of the ICX-500 Gateway.

The ICX-500 gateway runs an embedded web server. It allows the users to log in using a standard web browser such as Chrome or Firefox to operate and manage the ICX-500 system. The web server provides functions for system monitoring, configuration, and software upgrade.

Initial connection

Connect the laptop to Eth0, and enter 169.254.1.5 in the web browser

Logging in

Initial connection is done by connecting a laptop to Eth port 0, open a web browser (e.g. Firefox or Chrome), and type in the IP address in the address field of the browser:

The Login page

Default IP address 169.254.1.5
Default Username: admin
Default Password: alphaadmin

These credentials will give Read/Write privileges, making it possible to do changes in the configuration.

To log in with Read privileges only, the credentials are:

Default Username: alpha
Default Password: com

With these credentials one can check status and read information, but not make any changes to the system.

Changing Default User Name and Password

For security reasons it is recommended to change the default user names and passwords.

Select System Configuration > User Management
Enter the Current Password for both Read access and Read/Write access (default: com and alphaadmin)
Enter new User Name and Password
Re-enter the New Passwords to confirm
Verify by clicking Update User 1 and Update User 2
Write down the selected passwords and keep them in a secure place.

Saving and Applying changes

When new configuration parameters are entered, they are saved to the configuration file by clicking Save. To apply the new settings to the running configuration, click Apply.

System Monitoring

Node Information

Shows general information about the system such as Node Name and Node Number. It also shows state information; different times and memory usage. Information about the Software Configuration, and the Hardware Configuration (the different boards and versions), and also the state of the different processes running in the system.

Node Information

Node name: The name of the gateway, as configured from AlphaPro, Exchange & System > System menu.
Node number: Default node number is 1. The node number is used for communication between gateways interconnected in a network (AlphaNet). The node number can be changed from AlphaPro, Exchange & System > System menu.
Operational: Enabled: The intercom application (vs-amcd) is running. Disabled: The intercom application is not running.
Active Calls: Shows the number of currently active calls. Refresh (F5) the web page to see current status. If there is a need to restart the system, one can wait until there are no active calls in the system.
Current System Time: Shows the current time in the ICX-500, as presented in display stations.
System Uptime: The time elapsed since last time the system (Linux) started

See Multicast for more details.

Unconfigured

The "Unconfigured" list shows stations that are able to connect to the ICX-500 gateway, but not able to register.

Typical reasons for not being able to register are:

The directory number specified in the station web does not exist in the ICX-500 gateway
The "CCoIP Station" flag is not enabled

Check "Directory Number" and "CCoIP Station" flag settings in AlphaPro, Users & Stations.

Stations/Devices - Unconfigured

AlphaNet/SIP Trunks

This table shows all AlphaNet and SIP Trunk connections.

System Monitoring - AlphaNet

The table shows:

Node ID: Unique index number (1 - 254) of the ICX node or the SIP Trunk node
Node Prefix: The prefix to dial on the intercom station to reach that node
Name: Shows the name of the node. If the name is changed from AlphaPro, a small reset is required for the name to be updated.

- AC_IP: AlphaCom or ICX node.
- SIP: SIP Trunk node.
SW Ver: Software Version of the node
Node IP: The IP Address of the node
Status: Shows the communication status to the remote node
- Up: The communication with the node is OK
- Down: Communication error with the node

Ping (ms): Shows the response time to ping request to the remote node. If no response from the remote node, it will show "No answer".

Audio Statistics

The ICX-500 collects Audio Statistics and RTP Statistics for local calls as well as for AlphaNet and SIP Trunk calls. The statistics are cleared when the ICX-500 is reset.

Audio Statistics

Audio Statistics:

Connection Type: Local calls inside this node, AlphaNet calls or SIP Trunk calls.
Connection Path: Shows between which nodes the statistics are for
Seconds of Audio: The total time of audio for all conversations
Connections: The number of connections since last reset
Max Lines: The peak of concurrent calls

RTP Statistics:
Click on View Details on one of the connections to see detailed RTP statistics for that connection:

Time (sec): Total duration of connections
Connections: Number of connections
TxPacktes: Count of RTP packets transmitted
RxPacktes: Count of RTP packets received in time playout
RxLate: Count of RTP packets received too late for playout
RxLost: Count of RTP packets not received at all
RxLost (‰): (RxLate / RxPacktes) * 1000
RxLost (‰): (RxLost / RxPacktes) * 1000

The "Jitter Avg" and "Delay Avg" are average values of the last 10 connections:

Jitter Avg (ms): Jitter computed as in A.8 of RFC3550, sampled once every second, and converted to milliseconds.
Delay Avg (ms): Localt Rx jitter buffer delay, sampled once every second, and converted to milliseconds.

Log

Log files stored on the ICX-500 gateway can be viewed or downloaded by selecting System Monitoring > Log.

View Logs

To view a log file directly in the browser, Select Log to read, then press Submit.
To download the log file, press the link under Filename, and store the log file on the laptop

By default logging is disabled. To enable logging, select System Configuration > Logging

System Configuration

Interfaces

There are two Ethernet interfaces on the ICX-500 Gateway, Eth0 and Eth1. The IP address is set by using CIDR notation. It appends a slash character ("/") to the address and a decimal number specifying the number of bits (out of the total 32 bits of an IP address) that the network prefix consists of.

Factory Default settings are:

Eth0: 169.254.1.5/16
Eth1: 0.0.0.0/32 (obtain IP Address automatically - DHCP)

Enter the IP address, press Validate, and then Save & Apply.

IP address and subnet mask is defined in CIDR notation

It is highly recommended to use Static IP addresses on the ethernet ports

Examples of CIDR notation and equivalent dot-decimal notation:

169.254.1.5/16 is equivalent to IP address 169.254.1.5 and net mask 255.255.0.0.
10.5.101.30/24 is equivalent to IP address 10.5.101.30 and net mask 255.255.255.0.
192.168.1.40/26 is equivalent to IP address 192.168.1.40 and net mask 255.255.255.192.

See here for more examples.

Routes

The Routing table must be configured if there is a need to communicate with devices outside own subnet. Three different route types can be defined:

Default route (= Default gateway)
Net route - A route to one particular IP network
Host route - A route to one particular host

Defining a Default Gateway

To define a Default Gateway, select Add New, and enter:

Destination net = 0.0.0.0/0
Gateway on local subnet = IP Address of the default gateway
Interface = On which Ethernet interface the default gateway is located
Press Validate
Press Save & Apply

Defining 10.9.8.1 as the Default Gateway on Eth1

Only one Default Gateway must be defined.

Defining a Net Route

To define a route to one particular network, select Add New, and enter:

Destination net = IP address of the remote IP network in CIDR notation
Gateway on local subnet = IP Address of the gateway
Interface = On which Ethernet interface the gateway is located
Press Validate
Press Save & Apply

Defining a route to the network 10.9.3.0 via gateway 10.9.8.1 on Eth1

Defining a Host Route

To define a Host route, select Add New, and enter:

Destination net = <IP address of the host>/32
Gateway on local subnet = IP Address of the gateway
Interface = On which Ethernet interface the gateway is located
Press Validate
Press Save & Apply

Defining a route to the host 10.9.3.40 via the Gateway 10.9.8.1 on Eth1. Note that the CIDR mask must be "/32"

Filters

The built-in firewall of the ICX-500 Gateway is by default configured for management services (AlphaPro, Web Interface) on Ethernet port 0, and VoIP services (e.g. IP- and SIP stations, AlphaNet) on ethernet port 1.

Default Filters Settings

In the Filters settings one can modify what services should be available on each ethernet interface.

ICX-Alphacom can not use any TCP port below 1024. These ports are Priviliged ports, which is a Linux security feature

New TCP or UDP ports can be added by selecting Add Filter. Remember to enable it after adding!

Adding TCP port 4001 to the Filters

Stations/Devices.

From the Stations/Devices list some user parameters can be modified.

The table can be sorted by clicking on the relevant header. In the Search field you can search for any free text, e.g. directory number, display text or IP address.

Stations/Devices

By clicking on a station in the list, the following parameters can be modified:

Directory Number
Display Text
COS (Class of service)
Volume
Noise Reduction
Always Private

Modify station configuration

Changes will take immediate effect. No reset is required.

Configuration changes done from the ICX web interface are stored in the ICX-500 Gateway. In order to syncronize AlphaPro with the actual configuration of the ICX Gateway, it is important to perform a GetAll from AlphaPro

Quick Edit Mode

When multiple changes are to be made, the Quick Edit Mode can be enabled, and each parameter can be modified directly from the table without having to open an extra window.

Quick Edlt Mode let you do multiple edits in an easy way

Remember to click on Apply Changes to save the changes.

Logging

There are three different log types:

Debug Log: Low level messages. For debugging purposes for software engineers.
System Log: Provides log events for monitoring the health of the ICX system. The log includes Station Line errors, restart, backup/restore, Customized event logging (LOG command) etc.
Call Statistics Log: Detailed information about Calls, Call Requests, Group calls, external SIP trunk calls

There are four different log Destinations:

Local Filesystem - Log files are stored locally on the ICX-500 Gateway. Logs can be viewed or downloaded from System Monitoring > Logs
Remote SysLog - Enter the IP Address of the remote computer, and the protocol type (UDP or TCP)
E-Mail - If the ICX-500 has access to an e-mail server, log events can be forwarded to a predefined e-mail address
SNMP Trap - Enter the IP Address of the remote computer running the SNMP service. Select SNMP System Information to configure additional SNMP parameters (Name, Location, Contact, Community String and SNMP Port).

Log configuration

To configure logging press Edit next to the Destination, and enter relevant parameters. The different logs are enabled by setting "Pri Level" = Info.

Enable logs by setting Pri Level = "Info"

After changed are Saved and Applied, the logging can be tested by clicking on "Generate test log messages".

To filter on a specific text in the log strings, add the required text in the Contains field. Only log events that contain this text will be sent to the log.

Logging to Local Filesystem
The log system is creating a new file every day for each of the log types (Debug, System and Statistics).

Log rotation is used to prevent the logs from growing out of control. Every 10 minutes there is a check if the log files are consuming more than 20MB of memory space. If more than 20MB, the oldest log file will be deleted, until the remaining space is below 20MB. I.e. you will loose one day of logging each time a log file is deleted.

Log Space in Local Filesystem

Clean up will remove 10% of the oldest log content. Delete will delete the complete log file.

Licensing

For how to obtain and install licenses, see Licenses for ICX-500 and ICX-AlphaCom Core.

Installed licenses are displayed in System Configuration > Licensing.

ICX-500 License management page

The ICX system comes with a 20-day free license period. Until valid licenses are installed, the remaining time of the free period is displayed.

From factory there is a 20-day free license period during which all features can be used without the need of any license.
When the free license period expires, there must be a valid license installed, if not the licensed feature or device will cease to operate

License Configuration - Free license period

User Management

From the User Management page the username and password for logging into the ICX can be changed.

User Management Form

For security reasons it is highly recommended to change the default username and password.

Default username/password:

Read User: alpha/com
Read/Write User: admin/alphaadmin
Custom Script User: scripter/alphascripter

AlphaPro is using the "Read/Write User" credentials.
High Availability system (IPHA) is using the "Read User" credentials for updating configuration data between the two ICX gateways.

Time and Date

Time and Date Settings

The Time and Date section shows the current time zone configured.

In the Select New Region section a new time zone can be configured. When a valid time zone is configured, the ICX will automatically adjust for daylight saving time.

In the Set Localtime section, the date and time can be manually set.

In the Configure Network Time Protocol (NTP) Server section the ICX can be configured to synchronise the time to a Network Time Protocol (NTP) server. Enter the IP address of the NTP server, then Set Server. The ICX will now check if this is a valid NTP server, and display a message accordingly. The connection to the NTP Server can also be tested by the Test Server button. The button Get Time will instantly read the NTP time and set the time and date.

When the ICX is configured to use NTP Server, the time and date is automatically synchronized approx. each minute.

NTP Clock Drift Adjustment: If there is no NTP Server available at site where the ICX500 Gateway is to be installed, there is an option to temporarily connect the ICX to a network with NTP Server during commissioning (e.g. in the workshop before shipping to end customer). Configure the ICX to synchronize the time to this NTP server. Now the internal ICX clock will be compared to the NTP time, and the offset will be calculated. One should leave the ICX connected to the NTP network for at least 24 hours to get the best result. When the ICX is moved to a network without NTP Server, it will use this offset value to correct the real time clock in ICX.

When an offset value has been calculated, the Slew will show a value, and the Update Time will show the date and time when the offset value was stored.

DNS

To define DNS service:

In System Configuration > DNS, press Add new
Enter the IP address of the DNS server in the IP address field.

Defining a DNS service

Hostnames

To configure a Host name:

In System Configuration > Host Names, press Add new
Enter the Host Name and IP address.

Defining a host name

When interfacing the ICX system to an external SIP PBX, it might be that the SIP PBX require "Host name" instead of IP address. Then this Host name table can be used, see SIP Trunk - Host name

DHCP server

The ICX500 Gateway can be configured to act as a DHCP Server, and automatically provide and assign IP addresses to client devices (e.g. intercom stations).

Make sure that the DHCP server does not conflict with other DHCP servers on the local network!

To configure the DHCP Server:

In System Configuration > DHCP server, press Add new, and select which Ethernet Interface to use for the DHCP server
Select IP address range start and end.
Select the Lease time. The lease time is the period of time that the IP address is allocated to the device. At the end of the lease, if the device have not yet renewed it, the IP address is free to be handed out to another devices. Default lease time is 1 hour.

DHCP server configured to hand out IP addresses in the range 192.168.10.100 to 192.168.10.199

The DHCP server will provide:

An IP address in the range specified
The Subnet Mask will be the same mask as used by the ethernet interface specified
Gateway address will be the same as the default gateway address defined in the ICX Routing table. If no default gateway is defined, it will use the IP address of the ethernet interface it self
DNS address - the IP address of the ethernet interface it self

As IP addresses are handed out, the devices will appear in the DHCP Leases list:

List of clients that have been assigned an IP address

Make sure that DHCPv4 server (UDP port 67) is enabled in Filters for the Ethernet interface used for the DHCP service

Messaging

From the Messaging menu one can upload two types of voice messaging services:

A complete Voice Language Package - containing a set of Help messages, Absence messages, Information messages and Alarm messages
Custom audio files

Messaging menu

Install Voice Language Package:

Download the language package for the language you want to use. The file is on .deb format
In the "Upload ASVP Package (.deb) File" section, Browse to the file, and Upload. The voice services will take effect immediately, no restart required.
Several language packages can be uploaded. If so, you need to select from the drop-down list which one to use.

Absence, voice mail and alarm messages require that the license "1002604100: ILF-M-ENH - Enhanced Audio Messaging License" is installed
Help and Information Messages are available without license

Upload Custom audio files:

In the "Upload Custom Wav File" section, select Message Group, Group Index and Browse to the file you want to upload.
The file will be renamed when uploaded. Name format : svp_xxx_yyy.wav, where xxx=message group and yyy=group index.

Examples of Message Groups and Group Index:

Message Group 30, Group Index 1 - 9: Alarm messages 8191 – 8199
Message Group 10, Group Index 47: Call Request message ”Your call is registered, please wait”

Wav file format required: 16 bit resolution, 16 kHz sample rate, Mono
Custom audio files require an Audio Messaging license:
- 1002604000: ILF-M-BAS - Basic Audio Messaging License (Up to 10MB, max 3 alarm messages)
- 1002604100: ILF-M-ENH - Enhanced Audio Messaging License (Up to 50MB)

High Availability

TBD

SIP Number Translation

From the System Configuration > SIP Number Translation menu, one can upload a CSV file, which is used for number translation on incoming and/or outgoing SIP Trunk calls. When the CSV file is uploaded, the content will be displayed in a table in the web page:

SIP Number Translation table

The file name must be sip_config.csv, and the format as follows:

Number translation;;;
Type;Internal;Public;
in ;110;22222900;
out ;120;22341567;
bi;2563;40002563;
in ;-;*;
out ;*;40002500;

The first two lines of the file are ignored and are used for description of columns in Excel. (The order of the rest of the lines is not important.)

The CSV file can be uploaded, edited and saved from Excel:

sip_config.csv in Excel

First column "Type"

"in" Translation used for incoming calls, the destination number will be matched with "Public" and replaced with "Internal" number.
"out" Translation used for outgoing calls, the source number will be matched with "Internal" and replaced with "Public".
"bi" Translation used for both incoming and outgoing with the above rules.

Second column "Internal"

ICX intercom number

Third column "Public"

Public phone number

Special characters
*: If no match found, use this entry (Can only be used for "in" or "out", not for "bi")
-: When used for "in" - Internal number, the reply on SIP will be "404 not found". (Use it with public number "*", to reject all undefined numbers).

If no match and no "*", the number will be sent as is to ICX.

Explanation of the example file

in ;110;22222900;

When receiving an incoming SIP trunk call from phone number "22222900", the Internal number 110 will be dialed.
The “To” field in the SIP Header is changed from 22222900 to 110, and the call is routed to 110.

out ;120;22341567;

When making an outgoing call to the SIP trunk from Internal station 120, the source number will be "22341567"
The “From” field of the SIP Header is changed from 120 to 22341567, causing the Caller ID at the receiving side to be 22341567.

bi;2563;40002563;

Incoming calls from phone number "40002563" will be routed to intercom station number "2563". On outgoing calls from intercom station "2563" the source (Caller ID) will be "40002563".

in ;-;*;

Incoming calls from other phone numbers than 22341567, 40002563 and 22222900 will be rejected with the SIP response "404 Not found"

out ;*;40002500;

For all other stations than 120 and 2563, the source number will be 40002500 for outbound calls.

Other example:

replace  "in ;-;*;" with
in ;100;*;

For all incoming calls from other than 22341567, 40002563 and 22222900, the call will be routed to Internal number "100"

Use case: Direct Dial-In (DDI) (aka Direct Inward Dialing DID), where a series of public phone numbers are routed directly to predefined intercom stations. When an outgoing call is made from an intercom station, one can manipulate the source of the caller (Caller ID) to be the public phone number instead of the intercom station number.

System Maintenance

System Recovery

From the System Maintenance > System Recovery menu one have the following options:

Small Reset: Reset main applications
Reboot: Reboots the complete system
Chilly Restart: Reset main applications and clear state data like mails, call forwarding, absence status, UDDs and audio program selection. Configuration data is kept.

Backup and Restore

From System Maintenance > Backup and Restore one can create backup file and restore backup of the ICX system.

The Backup and Restore menu

Create a backup:

Press the Backup button. This will generate a backup file which is stored locally on the ICX system, as well as on your computer. You can choose to Include technical debug information. Normally you include debug information only if you have issues with the system, and want to forward the backup file to a support engineer for analyses.
An alternative way to create a backup file is to dial 7820 + M-key from a SuperUser station.
The backup files will be listed under the "Restore" section. There may be several backup files. Each file is identified by its date.

Backup of the Configuration Slave in a system with redundant servers (IP-HA) is not supported

Upload backup from a laptop:

Browse to the backup file (.tar.gz file extension), and Upload.
The backup file will be listed under the "Restore" section, with date and time from when it was uploaded.

Restore a backup:

Click on a backup file listed under the "Restore" section. More details will be displayed:

Backup file - expanded view

The following options are available:

Keep IP settings: When checked, the current IP settings in the ICX will be kept. When unchecked, the IP settings from the backup file will be used
Restore license: When checked, the license from the backup file will be used. When unchecked, the current licenses in the ICX will be kept.
Restore messages: When checked, any Custom audio wav files in the backup file will be restored. Existing audio files will be replaced if the file name is identical. When unchecked, any wav files in the backup file will not be restored.

Restore: Will install the backup on the ICX system.
Delete: Will delete the backup file from the ICX-500
Download: Will download a copy of the backup file to your computer

Storage device:

By default the backup file is stored on the Local flash memory of the ICX-500 (as well as on the computer creating the backup). If a SD Card is inserted in the ICX-500, one can choose to store backup file on the SD card instead.
After the SD card is inserted, reboot the ICX-500, then select Check for device. The "SD card" should now appear as an option:

Select if Backup file should be stored locally in ICX-500 or on the SD card

Note that when "SD Card" is selected, backup file will not be stored locally.
