KSU-less phone systems will be cheaper than any system with a central control unit. Full KSU and PBX phone systems will be more expensive, with central hub costs approaching £!,000 in many cases and good quality handsets running at £100 or more. For an SME with up to 20 extensions, the installation cost is likely to fall in the range of £1,000 to £5,000. For quick reckoning, many experts budget on around £200 per extension.
For larger organisations, more sophisticated technology, a greater training requirement and the need for more maintenance can easily push the cost-per-extension up to £500 or more.
Whatever the eventual solution, project pricing will include these three main components:
- Start-up costs
- Regular maintenance costs
- Internal staffing costs
