Hi , I am unfamiliar with the above system and would appreciate any help . The customer has 3 analogue lines working and wants to have a 4th added . I've had a look online at the install manual , but very limited program info . Looking at the system / nttp , I think they had a 4th line at some time in the past , which was ceased . Hopefully , all I would need is the code to enter prog mode , and the code to enable the line . This system also has " lg nortel " written on the cover . Many thanks
