Complete System Examples
Each of these configuration examples show fully itemised costings, "pop-up" explanations for all items and links to the relevant product page.
If you are not sure exactly what you need you will find these pages invaluable. Used in conjunction with other areas of the Phones4Less site, in particularly the Buying a Phone System section and most importantly the ISDN In English section, you will soon know as much about telephone systems as we do.
