A method for call-logging is provided. The method includes monitoring packet headers transmitted from and received by a port associated with a computer device. Next, the port number of the computer device is determined. Subsequently, an identification is made as to whether a communication channel for passing data has been established. If the communication channel has been established and the port number is determined to be associated with an H. 323 application then the method moves on to record call start time. When the communication channel is terminated the method proceeds to record the call end time. Thereafter, the call duration is determined by subtracting the call start time from the call end time. After that, a calendar application is invoked and the call duration is logged into the calendar application.
