  • Network switch employing a proxy to facilitate power savings in a telephone network
    Patent number: 9065685
    Abstract: In an example embodiment, an IP phone is connected to a network switch that has an established communications channel to a call control server. The network switch acts as a proxy for the phone exchanging registration information that in effect keeps the phone registered while the phone itself can go to sleep as defined by periods of the day, periods where the phone is unused, or presence, which can then wake-up quickly with assistance from the switch. If the switch is not able to act as proxy, the phone can switch from sleep mode to “wake” up mode at predetermined intervals, such as every 30 seconds, in order to respond to keep alive packets from the call control server.
    Type: Grant

    Assignee: Cisco Technology, Inc.

  • Method for establishing voice communications using a mobile handset
    Patent number: 7711370
    Abstract: 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.
