Telio develops, installs and operates communications and media systems, which make an important contribution to institutional peace and rehabilitation in prisons and forensic commitments alike. Every system adheres to the highest security standards, simplifies work processes significantly and has a rehabilitating effect. since 1998, Telio has specialised exclusively in this field and is today arguably the most competent partner in this segment in all of Europe. Products emerged such as the acclaimed PHONio prison phone system (also available as a patient phone), the CALLio cell call system, the BLOCKio mobile phone blocker, CAREio telephone counselling, the MULTio cell multimedia system and many other ideas that drive us every day to simplify the daily work of law enforcement officials and thus contribute to rehabilitation.
