IT support companies love hosted VoIP because it provides a range of benefits for their clients, including cost savings, flexibility, and ease of use. IT support companies can easily set up and manage phone systems for their clients, without the need for extensive on-site hardware installations. Hosted VoIP also allows for easy scalability, meaning businesses can quickly add or remove phone lines as needed. Additionally, many hosted VoIP systems offer advanced features like call routing, voicemail-to-email, and mobile integration, further enhancing the efficiency and productivity of businesses.
