Typically, businesses have equipped their offices with PBX phone systems, as well as other similar tools, such as IP Telephony systems, for employees, managers, and chief executives to make work-related phone calls. This comes with a much needed ability to keep track of usage across a company’s phone lines. These PBX phone systems allow for logging of records in order to provide reporting, typically with the help of add-on software. This way, businesses get the cost allocation and cost visibility that’s needed. This way they can keep track of who is using which phone lines, who they are calling, and what kind of telecom expenses are associated with it. Phone calls are rated and the data is easily retrievable. All of this allows managers and employees to verify calls that have been made, and finance teams to access the required data to chargeback departments the costs associated with their extensions.
