Voice over Internet Protocol (VoIP) is an increasingly popular alternative to traditional telephony for businesses, offering cost-effectiveness, reliability, flexibility, improved sound quality, feature-rich services, easy scalability, seamless integration with other applications, and quick setup. However, it also has some disadvantages such as dependence on internet connection, security concerns, and limitations in locating emergency service users accurately. Despite these challenges, VoIP is a natural choice for businesses looking to transform and future-proof their communication systems, especially those accommodating hybrid employees and customers.
