The present invention permits the real-time voice input of a mobile phone handset to be sent to a networked device via mobile data networks, without the involvement of broadband wireless networks such as Bluetooth, WI-FI or WIMAX. Currently, much work has been done to enable VoIP communication via the WI-FI protocol. WI-FI access requires the mobile handset supporting WI-FI feature, and the presence of WI-FI gateway, typically installed in hot spots such as airport or coffee shops. This is not ideal as the combination of these two criteria means that only a small fraction of the handsets that support WI-FI can make such VoIP calls and only when the users are within a hot spot. The present invention eliminates these limitations and enables voices to be transmitted to the mobile data network directly, whenever and wherever there is mobile phone dial tone.
