private automatic branch exchange (PABX)
A private automatic branch exchange (PABX) is an automatic telephone switching system within a private enterprise. Originally, such systems – called private branch exchanges (PBX) – required the use of a live operator. Since almost all private branch exchanges today are automatic, the abbreviation “PBX” usually implies a “PABX.”
Private Automated Branch Exchange (PABX) is a phone switching system that widely used in offices and plants, allowing a single access number to offer multiple lines to outside callers while providing a range of external lines to internal callers or staff.
Top Choice Surveillance Limited provides a full range of PABX systems including analog PABX, IP PABX and Hybrid PABX. The IP PABX uses “Voice over Internet Protocol” (VoIP) technology to transform high speed internet service into a phone line to convert voice into digitized packets and then put the digitized packets onto the data network. It can easily adapt to any business, helping clients increase employees’ productivity, improve customer service and reduce cost, bring long term benefits for scalability, manageability and enhanced features.
