A device permits a conventional, analog telephone to connect to a smart phone to provide access to various smart phone features from the analog telephone. For example, the analog telephone can receive or initiate calls and send or receive texts and may provide a secure access point to home automation devices, including Amazon Alexa, Google Home, or the like. The device may be a stand-alone device that connects to an analog telephone or may be integrated into a telephone of any desired design or style. A smart phone application may be used to connect the smart phone to one or more devices to selectively activate features of select ones of the analog telephones. In some embodiments, the device can have its own subscriber identity module (SIM) and its own telephone number to directly send and receive calls or text messages.
