Configuring a VoIP Phone Using Automatic Registration on the NEC SL2100 or SL1100

Automatic registration allows an IP phone to be pre-programmed with an extension number and password using a Personal ID Index, streamlining deployment—especially for remote installations.

Get Connected

This procedure requires access to the NEC SL2100 using the PCPro Programming Software.

To download PCPro or learn how to connect to the phone system, refer to:
How to Connect to the NEC SL2100 or SL1100 Phone System for Programming

⚠️ Tip: We strongly recommend completing this procedure before deploying the phone to a remote location.

PCPro Programming Steps

In this example, we’ll use extension 109, but you may substitute with any available extension.

  1. Go to Program 10-46: DR700 Server Information Setup
    • Set 10-46-01: Register Mode to Automatic
  1. Enable IP Phone List Access
    • Click the Filter Options tab (top of the PCPro window)
    • Click the IP Phone List… button
    • In the pop-up, check the box next to each extension you plan to use with an IP phone or IP DECT handset
  2. Go to Program 84-22: DR700 Logon Information
    • For Personal ID Index 001, enter:
      • User ID: 109 (your extension number)
      • Password: 1234
    ⚠️ Note: Passwords must be numeric. Alphanumeric values will not be accepted by the IP phone during registration.
    • Repeat for each extension you plan to use
  1. Go to Program 15-05: IP Phone Basic Setup
    • Use the Extension dropdown to select extension 109
    • Set 15-05-27: Personal ID Index to match the index used in Program 84-22 (e.g., 001)
    • Repeat for all additional IP extensions
