About Cetis


Cetis, Inc., formed through the 2006 merger of Scitec and TeleMatrix, and the 2009 acquisition of Teledex assets, designs and manufactures a broad range of analog and VoIP telephones and high-speed Internet products. Designed and engineered in America and Europe for hotel, resort, enterprise, SMB, SOHO, healthcare, education, military, and government applications, Cetis products are built to exacting standards, and backed by our global distribution and support network.

In 1986 we introduced the first Teledex brand hotel telephone with programmable guest service keys and a customizable faceplate area. Four years later, in 1990, we introduced Diamond Series telephones, which continue to be recognized as the most popular hotel guestroom telephones in the world. Today, it is estimated that more than 7,000 Cetis channel partners have installed more than 30 million Cetis telephones at 100,000 commercial locations globally. Growing globally? Cetis leverages its own global resources to provide a single point of contact to quickly respond to sales and support inquiries anywhere in the world.

Experienced and knowledgeable Cetis sales directors, supported by the Cetis customer service and SIP support teams, are strategically positioned globally to meet the most demanding requirements of Cetis customers and channel partners seeking assistance with product selection, pricing, faceplates, programming, order placement, and post-delivery support.
