How to Replace An Existing Phone System

Installing a phone system is not for the faint hearted. Even if you  have a technical background you will need special tools such as the krone tool, cable tracer, RJ12 crimping tool along with the usual cutters, knife, drill and screw drivers.

From an installation perspective, a phone system has 2 sides. Lines coming in & extensions coming out. When I install a system, I usually start by identifying how the lines and extensions are connected to the existing system. Most phone systems have 25 pair tails that connect either to the system or directly to the cards inside. Identifying what is what is one of the most difficult parts of installation because there are some many brands and models of phone systems out there that chances are you wont know the how things connect to the old system. This is where a bit of experience really helps.

Generally I start by asking the customer how many lines they have. If they have 5 analogue lines then I will go back to the 25 pair tail and look for 5 red and white jumpers all next to each other. I will then connect my analogue test phone on each line and make sure they are the lines. The extensions usually make up the rest of the jumpers connected to the tail. If there is 15 phones then you should see roughly 15 jumpers plus the 5 for the lines.

Now that you have determined what is what, remove the old system and begin reconnecting the lines and extensions to the new system. Once you have done this and tested it, you will need to move on to the programming.

Programming a phone system can usually either be done via the reception handset (the first extension) or via software loaded on a PC. If this is the first system that you are installing, you should be using the software on the PC as it is far easier to understand what is what when you are looking at a nice windows based GUI.  The problem is, you might find it hard to get the appropriate software for your system as it is generally not given out to end users. Look on forums to see if someone has a link to a download.

Once you have the software it will be a case of trial and error to get things working they way you want. Phone system programming is generally broken up in to 5 sections:

  • Incoming Calls
  • Outgoing Calls
  • General System Settings
  • Extension Settings
  • Line Settings
