1. A method comprising:
facilitating, by proxying at a computing device, a communication session between a first device connected to the computing device through a wireless local link of a wireless local area network and a second device connected to a cellular wide area network, wherein the computing device is local to the first device during at least a portion of the communication session, and wherein the computing device directly connects to the wireless local area network and directly connects to the cellular wide area network via a cellular base station through a cellular radio as a cellular radio endpoint; and communicating, during the communication session, voice data transmitted via session initiation protocol (SIP), wherein the voice data comprises voice over IP (VoIP) packets, wherein the communication session includes a first communication path and a second communication path, wherein the first communication path connects the second device through the cellular wide area network to the computing device and then to the first device via the wireless local link between the first device and the computing device, and wherein the second communication path connects the second device though the cellular wide area network to the first device and does not include the wireless local area network, and switching from the first communication path to the second communication path, controlled by the computing device, when a signal quality of the wireless local link approaches a pre-determined threshold. |
