From Zenitel Wiki

This article describes the minimum configuration required for an INCA IP station to operate with an AlphaCom server. The IP Stations are configured through their web interface. IP Master Stations with display can also be configured using the display menu.

There are essentially three parameters to set in the station:

  • AlphaCom IP address
  • Station directory number
  • Station IP address

Configuration of the station

IP Station Web Interface

The IP Station features an embedded web server, which allows users to log in via a standard web browser. At commissioning, the IP Station needs to be configured to enable it to subscribe to an AlphaCom server/exchange. To do this, your PC and the IP Station have to be connected together via a PoE switch using network cables:

Connecting the PC and the station to a network switch
  • Connect the PC to the PoE switch
  • Connect the LAN port on the IP station to the PoE switch
LAN Port on IP Flush Master and OR Master Stations
LAN Port on IP Desktop Master Station
LAN Port on IP Substations
LAN Port on IP DualDisplay station

The factory default IP address of the station is 169.254.1.100. In order for your PC to communicate with the station it is necessary to change its Internet Protocol Properties to use an IP address that is in the same range as 169.254.1.100, e.g. 169.254.1.1 with subnet mask 255.255.255.0.

After the IP properties have been changed, access the IP Station by logging into the web interface using a standard web browser:

  1. Open a web browser
  2. In the browser’s address bar, type the default IP address 169.254.1.100 and press the ENTER key
-The station login page will be displayed:

To log into the station:

  • Click Login
  • Enter the default User name: admin
  • Enter the default password: alphaadmin

The Station Information page will now be displayed, showing the IP Station configuration.

Use the menu bar at the top of each page to browse through the different pages.

Main Settings

Click Station Main -> Main Settings to access the page for configuring station mode and IP parameters.

Station Mode: Select the Use Alphacom radio-button.

Registration Settings:

  • AlphaCom IP-address: Enter the IP address of the AlphaCom server to which the IP station is to be registered
  • Directory Number: Enter the directory number of the station. This must match the directory number defined in the AlphaCom server
- If a directory number is not entered, the station will register with its MAC address. The MAC address is found on the Station Information page and needs to be entered in the AlphaCom server using the AlphaPro PC tool

IP Settings:

  • DHCP – Select this option if the IP station shall receive IP Settings from a DHCP server.
  • Static IP – Select this option if the IP station shall use a static IP address. Enter values for:
- IP-address
- Subnet-mask
- Gateway
- DNS Server 1 (option for network administration)
- DNS Server 2 (option for network administration)
- Hostname (option for network administration)
  • Use Last IP On DHCP failure: If the station does not receive an IP Address from a DHCP server at startup, it will use the last IP address.
  • IGMP Version: Select IGMPv2 or IGMPv3 for multicast group membership.


Click Save followed by Apply to apply the new configuration settings

Voice Activity Detection (VAD)

Voice Activity Detection (or Sound Detection) samples the audio level from the microphone located in the IP Station. If the audio level meets defined criterias an action in AlphaCom can be triggered.

Configuration of the AlphaCom server

AlphaPro configuration

The station is defined in Users & Stations window, General tab. For minimum configuration you need enter these fields:

  • Directory Number - must match the directory number configured in the IP station itself
  • Display Text - Any free text. Used as Caller ID.
  • CCoIP Station - Tick this checkbox when IP Station (and not analog station) is used
  • Reg. w/Directory Number - When checked (most common setting) the station will register to the AlphaCom server by its Directory Number. When unchecked the station will register by its MAC address. You need to enter the MAC address of the station in the MAC Address field.
Users & Stations window


Note: In hybrid exchanges, where there is a mix of analog and IP stations, you should avoid using physical numbers that later might be used for analog intercom stations.

AlphaWeb configuration

Filter settings

Log on to the web interface of the AlphaCom server, and select System Configuration > Filters.

Enable "IP Stations" on TCP port 50001 and "VoIP Audio" on UDP ports 61000-61150 on the ethernet port used for the IP stations. By default these ports are enabled on ethernet port 1.

Enable ports for IP Stations


IP Station licenses

The IP Stations require IP Station license in the AlphaCom server.
