Professional Business Communications – from IP PBX to the CloudMitel was founded in 1973 by Michael Cowpland and Terry Matthews in Ottawa, Canada. After decades of experience in TDM PBX systems, Mitel has fully specialised in VoIP, unified communications (UC) and contact centre solutions. The acquisition of Unify in 2023 extended the portfolio with the established OpenScape and Unify product families. Mitel supports hybrid communication strategies: on-premises, cloud and hybrid scenarios within a unified system. Industry focus areas include healthcare, manufacturing, government, hospitality and multi-site enterprises. The product range covers IP desk phones, DECT handsets, softclients, IP PBX, UCaaS services and contact centre software. Lieske Elektronik offers Mitel endpoints and system components for B2B customers – with expert advice on migration paths from legacy TDM systems to modern VoIP infrastructures. |
