Siemens enterprise communications and Unify

HiPath and OpenScape hardware has carried three owners without a break in the product line.

  • 2008: Siemens moved its enterprise communications business into the Siemens Enterprise Communications joint venture.
  • October 2013: the company rebranded as Unify, inheriting the HiPath and OpenScape lines.
  • October 2023: Mitel completed its acquisition of Unify, so current support runs through Mitel.

Siemens-numbered boards (S30810 and related prefixes) are catalogued under Siemens. Tech-Star catalogues each part under its original badge: see Unify and Mitel.
