Phone Look is software that runs under Linux and Windows and talks to a PABX phone system via a serial port. The software is open source and released under the GPL licence.
It logs all outgoing calls and the relevant details including call time, length, numbers called and calculates the cost of the phone call. Data is stored on a postgreSQL database. Phone Look is mainly used in motels / hotels for charging guests for the cost of calls made from their room.
Reports can be generated on all aspects of phone call data using Papyrus.
