4.6. IP Centrex

IP Centrex is a hosted ‘virtual’ telephone system service that is similar to a private branch exchange. Unlike traditional Centrex, this system uses a broadband internet connection. Before considering an IP Centrex system, it’s advisable to conduct an audit of current and potential broadband availability together with your existing IT hardware.

Benefits

  • Uses sophisticated telephone system facilities controlled locally via a PC interface.
  • No financial outlay is required for telephone system hardware.
  • As equipment is provided by a supplier, it can be easily updated as technology advances.
  • Enhancements may be available to improve access for hard-to-reach groups.
  • Potential reduction in call outgoing charges.
  • Move/add/change costs for extra extensions may be reduced.

Costs

Some systems start at around £15 a month. There are no long-term contracts to sign and no capital investment in hardware is required. As incoming calls are diverted, extra charges may become expensive. 0800 or 0844 numbers may be required and consideration should be given to the potential extra cost to patients, as covered earlier on in the chapter.

Drawbacks

  • Monthly fees payable over a contracted period.
  • Managed by a third-party supplier – you have less control and there may be issues with service level agreements.
  • New telephone handsets are required for full functionality (a supplier may hire these to you or they can be bought outright).
  • Monthly charges for diverted calls may become expensive.
  • Relies on a broadband connection and reliable local IT hardware.
  • Local area network cabling is required.
