Colt's cloud UC service is now available across Europe. Applications can be accessed from mobile or desktop device, supporting the growing demand for mobile working and BYOD in the workplace, said the firm.
Colt's Cloud UC offering is a suite of managed cloud-based communication and collaboration services.
Richard Oosterom, EVP Voice Services at Colt, said: "For CIOs, a major barrier to UC adoption has been the lack of understanding of the business benefits, making it hard to argue the case for replacing expensive PBX and telephony equipment.
"The difficulty of then integrating collaboration tools with existing systems, and employing a team with the wide-ranging skills to maintain the services, has delayed the uptake of UC further.
"Colt's integrated voice and data network services removes those barriers and means that businesses can benefit from the digital transformation potential of UC, while still reducing both capex and opex costs."
