Verify the site LAN capabilities.

1. Check to be sure the site LAN has a DHCP server.

  1. DHCP greatly simplifies IP keyset setup since the keyset will automatically get an IP address when you plug it in.
  2. DHCP client is enabled by default in the DSX IP keysets.

2. Verify that the LAN has adequate bandwidth available to support IP calls.

  1. Installing a modest number of DSX IP keysets on a managed LAN should pose few bandwidth challenges. For example, four IP keysets (80KB worst case per keyset) would only require 320KB available bandwidth. Significant delays in a well-managed LAN are normally minimal.
  2. There are a variety of LAN performance testing and monitoring tools available to help you check bandwidth and delay, with some at little or no cost. One such example is Softperfect's NetWorx, but there are many more available.

Setting the System Options

1. Check the VoIP station port assignments.

  1. 1221-(01-64): VoIP Assignment [System: Ports: IP Stations: Assignment (1221/1222)]
    Verify the system's IP station port assignments.
    • By default, IP stations use:
      • Ports 101-128.
      • Extension numbers 401-428.
    Option Description
    Station Port Assign an IP port (1-64) to a station port (1-128)
    [Default] IP ports 1-28 are assigned to station ports 101-128 (extensions 401-428).
  2. Leaving the port assignments at default will make the initial installation easier.

2. Enter a password for the IP extension.

  1. 2106-02: Password [Stations: Config: Setup: VoIP: Password]
    Enter the password for the extension (24 characters maximum).
    Option Description
    Alphanumeric Extension's password (24 characters maximum). [Default] = no password entered.
    See the Name Programming Chart.
  2. For security to protect unwanted access into the system, the password you enter in this option must also be entered into the IP keyset.

3. Assign the extension's VoIP profile and check the VoIP port range.

  1. 2106-01: VoIP Profile [Stations: Config: Setup: VoIP (2106): Profile]
    For on-premise VoIP keysets, select VoIP profile 1.
    There are four VoIP profiles.
    • Profile 1 is preset for on-premise IP keysets.
    • Profile 2 is preset for remote IP keysets.
    • Profiles 3 and 4 are not preset, but contain the default value for each option.
    Each profile contains dozens of detailed VoIP parameters that you customize. However, it is highly recommended that you adjust the parameters only if you are a qualified IT administrator . For more on each of these parameters, see the following:
    Option Description
    1 [Default] VoIP profile for on-premise DSX IP keysets.
    2 VoIP profile for off-premise DSX IP keysets.
    3 VoIP profile 3.
    4 VoIP profile 4.
  2. Now that the system programming is complete, go to Connecting and Setting up the DSX IP Keyset Options.
