Optus is an Australian leader in integrated communications - serving more than six million customers each day. The company provides a broad range of communications services including mobile, national and long distance services, local telephony, international telephony, business network services, internet and satellite services and subscription television. In 2001, SingTel became the parent company of Optus, paving the way for Optus to become a strong and strategic telecommunications player within the Asia-Pacific region. Since commencing operations in 1992, Optus has invested more than $7 billion in the construction of fixed, mobile and satellite networks, including central business district, suburban local access networks, optic fibre, national trunk, Hybrid Fibre Coaxial and international undersea cables. These networks provide the company with an advanced technology platform capable of delivering cutting-edge communications, information and entertainment services. The mobile business unit has captured around one third of the total Australian GSM mobile market and leads the market in mobile data take up. The problem Optus was experiencing was that although it had two services to inform customers that they had missed calls, voicemail and Optus Surepage, their existed a portion of their customer base that subscribed to neither of these services and never knew if people where trying to contact them if they where out of coverage, had their handset turned off or where busy on another call. Due to the fact that these subscribers did not use voicemail for reasons such as they don't like having to retrieve voicemail and would simply prefer to return a call they know they missed Optus identified that it needed an alternative solution. This solution was the Missed Call Service. |
The Missed Call Service is a service designed to ensure that you never miss a call. In the event that you cannot be reached on your handset or you are not in a position to answer the call the caller is diverted to the Missed Call Service. The Missed Call Service will answer the call and prompt the user to enter a number to return their call on. This number is formatted into a message along with the time and date of the call and sent to your handset as a SMS. In the event that there is more than one call before the SMS can be delivered to the subscriber the system will modify the undelivered SMS message to include all the missed calls. The missed call project was a joint venture between IVSTEL and ITHL our Hong Kong based partner. ITHL was the project prime providing the solution to Optus with IVSTEL providing local project resources. The Missed Call Service was built using software written by ITHL coupled with hardware provided by Excel Switching Corporation and SUN Microsystems. The heart of the solution is the EXCEL CSP2000. This programmable switch provides ITHL with the flexibility to rapidly develop and modify the Missed Call Service to meet the needs of Optus. IVSTEL was used throughout the life of the project to manage and perform the following tasks as part of the project:-
