Embrace the perfect tool for key conversations—your voice.

We have supplied and supported Unify (formerly Siemens Enterprise Communications) systems since 1994. 

A Unify OpenScape telephone system will future-proof your office.  Even if you want the smallest, simplest, pick-up-the-phone-and-dial system at the moment, the Unify products are designed to expand as your needs expand - without having to rip out your existing equipment.  All the extra applications and goodies can be added at any time just by adding licenses, and most systems will expand to 500 users without having to replace your system. 

Who are Unify?

Born out of the engineering DNA of Siemens, Unify builds on a heritage of product reliability, innovation, open standards and security.  Whether you are a startup business of just a few people, or a mega corporation of thousands, Unify has a product for you and the track history to prove it.  Just watch the video below to see just how far they have come.

Unify OpenScape telephone systems are complemented by a full range of high quality OpenStage handsets.  The systems will also work with existing Siemens optiPoint handsets to make sure as much of your existing Siemens or Unify equipment can be reused with the newer OpenScape Business systems.  It is the policy of Unify to make everything as backwardly compatible as possible.  This ensures that not only can you use existing Siemens logo equpment, but that you will be able to get full use of anything you buy into the future.

About Us

Supporting start-up, small and medium sized businesses.

Mark WilsonDS Chiltern specialises in helping small and medium sized businesses.  Small businesses and start up businesses need a different type of service to larger businesses.  They typically do not have IT departments and professionals, and need a reliable service provider they can trust.

DS Chiltern, was formed by Mark Wilson (right) and has  been providing telecommunication solutions for over 25 years.  During that time we have built up a wealth of experience that we constantly call upon to help support and find the right solution for our clients.  With the knowledge we’ve gained over this time we can offer our customers a single supplier solution to meet all their voice and data needs


The portfolio we offer is very impressive, but we understand that that alone is not good enough for you to choose us.  That’s why we’ve worked exceptionally hard to make sure that the customer service we provide is equally impressive.  Our helpdesk supports Ericsson-LG iPECS users and provides technical sales support for spares and handsets.  Our Technical Sales engineers will also advise on complete systems and all the options available to you. 

We can offer you a full service that covers consultancy, project management, sales, installation, maintenance and training; which means from the moment you contact us we’re there to support and advise you. 


We also understand that technology is progressing at an incredibly fast rate so we only provide solutions that can be enhanced and upgraded as and when your business needs it.

Our customers are important to us, quite simply without them we wouldn’t be here!  So we’d like to thank them all for their continued support.
