3.1 LiftIP Programming

Before You Start Programming

  • Make sure that your phone supports tone dialling (some key phones and PBXs may have problems). By default, 2N® LiftIP receives DTMF via RFC-2833 or in-band detector (set in-band in parameter 1108 via the Service Tool only).
  • Complete all the values to be modified into a pre-prepared form, which provides a clear table of basic functions.
  • If your 2N® LiftIP is not brand new, make sure that you have the correct service password and, if you are not completely sure of your 2N® LiftIP configuration, execute full initialisation (Warning: The service password will also be initialised!).
  • There are two ways how to program 2N® LiftIP: remotely via a phone (using the phone number) or via the Service Tool (using the IP address).

Access to Programming Mode

You can only enter the programming mode during an incoming call (to the LiftIP number).

Enter the programming mode via the voice menu (press 9 for administration; press 1 to enter the programming menu).

You will be asked to enter the service password in the following format: service password  (remember to enter an asterisk behind the password).

If the password is correct, LiftIP announces: “You have entered the programming mode, dial the service or parameter number.

The default password is 12345 and you are recommended to change the password to protect your device against unauthorised persons.


  • The default password is 12345 and you are recommended to change the password to protect your device against unauthorised persons.
  • While entering the password, keep a timeout of 60 seconds (or any other value between 10 and 120) for each character to avoid LiftIP hang-up.

Programming Procedure

Having entered the programming mode, you can change any programmable value(s) in any order. Proceed as follows: enter the parameter (service) number and value. Use an asterisk as a separator or Enter. In general, the function has the following format:

parameter number  value 

The parameter number has three digits (see the table). After you enter the number and an asterisk,
2N® LiftIP reports the number, current value and potential range of the parameter to be programmed. After you enter the value and another asterisk, 2N® LiftIP announces: “New value stored”, or “Invalid value, new value not stored” if the value is beyond the allowed range.

2N® LiftIP reads the parameter number and new value for checking purposes.


  • A drawback of some phones is that they go “deaf” for a fraction of a second whenever you press a button (send DTMF). In that case, you cannot hear the whole text and are recommended to use another phone.

Programming Error

  • If you mistype a digit while entering a function/value and find it before clicking the asterisk, press to cancel the whole number and enter a new one.
  • If 2N® LiftIP rejects a parameter number or value, you can go on programming – re-enter the whole function number although you only typed a wrong value.
  • If you have programmed and saved a wrong value, re-enter a correct value.

Programming End

  • If you are calling 2N® LiftIP via a phone number, hang up to quit programming.
  • Press to return to the preceding menu.


  • If you are not quite sure of how 2N® LiftIP will behave after programming, save the filled-in form for later check.

Programming via Service Tool

This is the easiest programming method. Use the application to get connected to the 2N® LiftIP IP address.
