Judy Jones, Director at Call Connections:

"We have been using SonoKlaras at Call Connection for a year now and have found them a big improvement on products from the major manufacturers. Call quality for the agents is much improved and our experience shows they have far better protection from extraneous noises, a significant factor now most calls are to mobiles.  ElaraTek as a company is efficient, responsive and willing to work with us on innovative solutions. We are shortly to open another call centre and the new recruits will be fortunate as they will use SonoKlaras from the start."
