I maintain a custom fork of FusionPBX, currently based on version 5.1, which includes numerous bug fixes I have personally identified and resolved. While submitting pull requests can be challenging at times, I actively contribute, along with many others in the community. FusionPBX is an exceptional platform that I've relied on for many years in my VoIP business, and it has consistently met my needs. Additionally, we developed the FS PBX dashboard to enhance its user-friendliness, making it more accessible for both administrators and end users. It really makes us stand out against competition.
