In today's economy, businesses are looking for innovative ways to save money and be more efficient. One recent development in the field of business communications is the growth of hosted phone systems. Unlike conventional, or legacy systems, a hosted system relies on an outside provider to house and maintain a company's telephone communications. Using VoIP (Voice over Internet Protocol) technology, hosted phone systems free up companies from installation, maintenance and upgrade concerns, allowing them to focus on their more immediate business interests. Because hosted systems exist off-premise, companies can rely on increased security, reliability and features, as well as lower costs.
