本研究之主要目的為藉由國內第二大ISP業者－Seednet公司的Wagaly-Talk網路電話產品，透過個案研究方法進行該產品在推廣市場上的創新擴散模式相對驗證，同時進一步探討該產品如何運用創新特質及創新策略，達到一定的市場執行成效。本研究希望透過此個案深入檢視目前國內寬頻與通訊發展趨勢的高度連結特性，以及寬頻業者如何藉由自身優勢發展創新產品以建立市場競爭之利基。
數位聯合電信公司（Seednet）在台灣網通產業中扮演極重要的角色，並已在網路通訊市場中成功推廣網路電話「Wagaly-Talk」於數萬名家庭用戶日常生活中所使用，此一高科技產品成功推廣的案例值得借鏡參考，因此本研究採用個案研究法來分析研究2003年至2008年，網路電話「Wagaly Talk」的創新擴散現象。
本研究結論如下：
Seednet公司發展Wagaly-Talk網路電話產品的創新策略為何。
Wagaly-Talk網路電話產品的創新特質為何。
Wagaly-Talk網路電話產品的市場執行成效。
網路電話被視為是繼第一波電信革命（傳真機問世）以來的第二波電信革命，國內寬頻業者目前僅Seednet公司持續投資並耕耘家庭用戶市場，有鑑於網路與通訊市場發展漸趨向高度整合，相信不久的將來，隨著無線寬頻WiMAX的佈建與普及化，將有愈來愈多人開始使用網路電話，對國內寬頻及通訊的發展都將帶來更正面的影響。
