Analog PABX System
An Analog PABX (Private Automatic Branch Exchange) is a telephone switching system within a business or organization that routes calls between internal users and external lines using traditional analog phone lines. It functions independently of public telephone networks but connects to them via trunk lines, allowing businesses to manage calls efficiently with multiple extensions using a limited number of external lines.
Analog PABX systems are cost-effective, reliable, and ideal for small to medium businesses that require basic telephony functions without the complexity of IP networking.
