Development of an Innovative VoIP Student Attendance Recording Application

The persistence of high rates of absenteeism is a major concern, as it is believed by educators that consistent school attendance is essential for educational success, with low standards of academic achievement, including low levels of English language and literacy skills, almost universally attributed by teaching staff to high levels of absenteeism among the student body.
Several notable factors that influence student attendance and grades are motivation, prior grade point average, self-financing by students, hours worked on jobs, quality of teaching, and nature of class lectures. These factors lead to student behaviour, teacher attributes and course characteristics on class attendance and performance (Devadoss, 1996).
At Box Hill Institute of TAFE (BHI), attendance for international students needs to be reported using the approved method to BHI's International Student Office. It is mandatory that international students meet 80% attendance. One of the significant priorities for BHI was the application development to reduce time, error and administration overheads on reporting of attendance to government agencies in order to comply with regulations, especially with Educational Services for Overseas Students (ESOS) Act 2000.
While the world is moving towards an entirely unified voice and data network, voice-over-internet protocol (VoIP) is becoming increasingly popular. Converging voice, data and video networks are providing many positives for business and individuals alike. At present, nine Victorian Technical and Further Education (TAFE) colleges are looking to deploy VoIP or have already completed rollouts. Eventually there will be an estimated 9000 VoIP handsets in action in the state of Victoria. This deployment allows convergence of a number of technologies, including unified messaging services, virtual classrooms utilising videoconferencing, internet protocol television and other customised services (Le May, 2006).
BHI faces the common technology issues that constrain other institutes: limited funding and staff resources. Added challenges were that some students' families need their child's attendance and results to be communicated spontaneously, and some students lack a home computer and/or internet services. In late 2005, BHI fully implemented Cisco's voice system designed for educational environments that handles large call volumes without frequent busy signals, enables deployment of phones in every classroom, provides voicemail capabilities, and support for staff and students.
In 2007, BHI had over 22,000 equivalent full-time students, over 800 equivalent full-time staff, 11 major departments and four campuses, which mainly relied on funding from the Victorian State Government from Schedule Contact Hours. BHI offers more than 500 full-time and part-time courses, which range from one-week short courses up to two-year diplomas and a maximum of three-year degrees in several specialties. Budget and staffing constraints required that the new applications were created and implemented on existing funded infrastructure to maximise return on investment and reduce administration overhead. Implementation of new applications should be incremental and appreciable. Also its management and maintenance be both centralised and efficient, thus eliminating the need for frequent and costly service visits by contractors.
Due to the complex hybrid and manual procedures involved in the present system, it was a challenging task to come up with an innovative solution designed around available information technology infrastructure.
There are many VoIP solutions available commercially. At first we investigated Avaya, 3Com and Cisco products. Cisco infrastructure was already present at BHI and this made our decision easier as a preferred development platform. With respect to voice quality, high performance and reliability, systems integration, simplicity, and speed of management, Cisco's telephony products were preferred comparatively. …
