Many businesses with multiple departments have the need to allocate telecommunication costs per department or function. They need to be able to know which departments, groups, or individuals are responsible for calls that incur tolls, such as long-distance or international calls. In some cases, calls made via specific trunks may incur higher charges. These costs may need to be allocated to the appropriate department, group, or user. Businesses may also want to report on telecommunications costs in order to look for potential fraudulent use of resources. The Call Accounting module allows you to allocate costs (for outbound and inbound calls) to either a trunk, user, or user group. Using this module, you can create or upload one or more rate decks, and use those rate decks to calculate the cost of calls on the system. Basic call reporting functionality is also included.
