The Upgrade Path

Often you would think that you need to replace your current system in its entirety, but often this is not the case. A more cost effective way would often be to upgrade the central control unit of the telephone system. This comes more sharply into focus when you consider that the average system phone can cost between £100 to £250, so on a 10 phone system this can come to anywhere between 40%-60% of the overall cost of the system.So an option that allows you to retain the existing phones, could present a considerable saving over a completely new system. If your starting a new business or you system does not have a path to allow upgrades, then we would be happy to discuss the installation of either a new or refurbished system.
