Unify OpenScape Maintenance

Unify OpenScape Maintenance

Nexus IP is based in London and we provide telephone system maintenance to London and home counties via our fully trained engineers.

In the past, Siemens Communications merged with Atos and was rebranded as Unify.  Since then the Unify OpenScape Business systems were launched as replacements for their highly successful Siemens HiCom and HiPath and OpenScape Office range of systems that they had in the market for the past 20 years.

Our dedicated in-house engineers provide Unify business telephone system maintenance, not only for the new OpenScape systems, but we also support legacy systems that are no longer in production or supported by the manufacturer.
