Thats what our customers say

"The bluePBX employees accompanied the entire process, from the consultation to the rollout and commissioning. In addition, the support has done an excellent job to this day. Around 100 employees were able to communicate in a very short time at the same level as with our old telecommunications system would not have been possible and also not imaginable."

"Our new business park has around 20,000 square meters of office space and many different companies. We are very happy to have chosen bluePBX. We were convinced by the flexibility and ease of use. The service speed and product quality of bluePBX is particularly nice - traditional telephone providers can only learn from that!"

"We had a very expensive, high-maintenance and outdated hardware telephone system. That's why we wanted to step into it Make the future and switch to IP telephony. The cooperation with bluePBX was professional and goal-oriented. All our wishes were made possible in the implementation. The new solution is flexible and easy to use."
