Welcome To OpenVoice

We at OpenVoice specialise in providing high end telephony and unified communication solutions. We only use Unify (formally Siemens) to provide our systems, allowing us to focus on one set of products, making us one of the mostly highly skilled companies within this field.

We pride ourselves on our level of customer service, as all our engineers have the Unify accreditation we can give the highest level of support. We provide a white label service to other Unify resellers when complex solutions are required. We don’t employ any sales staff, all our work comes from recommendations.

The education sector is where we excel, we have the Unify Openscape Business solution running in numerous schools, academies and colleges. We know what is required from this sector, the solution we provide will always deliver with reliability, features, and all at a very competitive price.

What Our Customers Say

“We had a Unify telephone system put in at John Smeaton Academy by Openvoice back in 2014. They came out and worked with us on designing and setting up the best system for our requirements and we were, and still are, very happy with the solution. The ongoing support has been consistently fantastic, and they have been very easy to work with around any required upgrades since the solution was first put in. I would strongly recommend Openvoice to anyone looking to install a new telephony solution and would definitely be happy to use them again myself.”

Mark Newman Director for ICT & Data, Rodillian Multi Academy Trust

“We were introduced to OpenVoice through the company contracted to build our brand new school.
Although the technology involved was well beyond our level of knowledge, from day one Roger gave us total confidence in his ability to overhaul our outdated and sometimes chaotic systems which had evolved in a building that was over 60 years old and then to integrate them into our new school.
This he did successfully and we continue to have an excellent working relationship with OpenVoice’s aftercare being second to none.”
