METHOD FOR ESTABLISHING VOICE COMMUNICATIONS USING A MOBILE HANDSET |
摘要 |
<p>A mobile handset transmits a radio frequency (RF) signal. The mobile handset determines when it is in close proximity to a Voice over Internet Protocol (VoIP) capable device. If the mobile handset is in close proximity to a VoIP capable device, then the RF signal to the base station is disabled and a communications link is established with the VoIP capable device such that a call can be made by the mobile handset and routed as VoIP packets through the VoIP capable device.</p> |
