In an era where analog copper lines are being phased out, Hosted Private Branch Exchange (PBX) offers businesses a seamless, cloud‑based alternative that leverages Voice over Internet Protocol (VoIP). According to the Federal Communications Commission, legacy Plain Old Telephone System (POTS) services must be retired in the coming years, mandating a shift to digital solutions like VoIP and Hosted PBX.
