Platformity
We were looking for a reliable IP PBX solution as our conventional system had a lot of limitations. I'm happy with the solution and service provided by Inextrix. They gave us scalable IP PBX software and also integrated our CRM system and automated billing solution. This system increased productivity and ROI significantly.
