“SMEs are always looking for new ways to differentiate themselves, and can easily do so by visually communicating with their customers. Interactive mobile video for applications, communications and video conferencing is a strong growth engine for the small to medium-sized enterprise market, and will not only increase operational efficiency, but also give companies a competitive advantage.” said Alon Barnea, General Manager of RADVISION Mobility & Service provider Business Unit. “We are proud to play a role in the success 4com has achieved and believe this market trend will fuel more usage and traffic in the visual communications arena.”

“RADVISION’s advanced technology enables us to realize our vision to empower all types of businesses – no matter how small – to reap the benefits of video-enabled communications in the workplace,” says Edward Bodiam, Director of 4com. “Our back-to-basics approach to video services makes this important method of communications accessible to small and medium-sized enterprises, and RADVISION helps us deliver the best service we can to our customers.”

4com video communications solutions are available today and support both IP endpoints and 3G mobile devices. Advanced video communications is helping 4com customers increase customer retention and shorten business cycles, enhancing the way people do business and contributing to efficiency and the environment by reducing travel and waste.

“We were delighted to be involved in the early release of 4com’s video conferencing facility,” said 4com customer Nik Little, Director of Emery Little Insurance Brokers Ltd. in England. “The communication to our remote offices which are spread around the country improved dramatically. A video call has much more impact than just a voice call and indeed we conducted meetings via the system which otherwise would have meant four-hour round trip journeys. The long term prospects for this facility are very exciting.”
