If you are a small business looking for communications for anywhere between 2 and 40 users, BT Versatility is the one for you (and with the additional Broadband Module you could increase this to 52).
You can start with a couple of lines, confident that as you grow and develop, your communications can grow with you. Once you have chosen BT Versatility, simple 'snap in' modules let you install extra lines and more powerful tools and features later on, without having to take your system off the air.
