Before we begin, make sure the T4 Series VoIP Phone is powered up and connected to your network.
  1. Press the OK key on the phone and the IP address will be shown on the LCD screen.
  2. If you do not see an IP Address, check that the T4 Series voip phone is properly connected to the network.

  5. Once logged in, press the ACCOUNT tab, then select Account1
  6. Select ‘Enabled’ from the Line Active pull down menu
  7. Enter an appropriate name in the Label field – this is shown on the top right corner of the phone.

  9. Enter your User ID in the Register Name and User Name fields.
  10. Enter your SIP Password in the Password field.
  11. Enter the name or IP address of the SIP Server in the Server Host field.
