Making voice calls for faster information exchange is showing its increasing demands day by day. IP telephony is sensible in the view to provide such platform. IP telephony in heterogeneous network environments can prove its dominating characteristics while working on IP platform as compared with circuit switched network. Interface using SGGN gateway for IP telephony, to provide channel to all WiFi users to make voice calls to GPRS mobile user, can provide ultimate solution for the need. In the existing EPBX system this can be used as add-on feature. Data traffic on existing GPRS networks have proved reliability in terms of less delays and cheaper way of information exchange. At the same time VoIP on WiFi network is shwoing increasing demand for corporate VPNs today. Interconnecting these two will provide more reliable and single device-multi interface platform and add more flexibility to its users. Unlicensed mobile access using WiFi can provide such integration of different networks together. The analysis has been done by simulating unlicensed mobile access (UMA) on NS2. Analysis indicates that the system can perform better for maximum number of users with less end to end delays and optimum throughput.
