A system capable of connecting a home telephone circuit connected to a Public Switched Telephone Network (PSTN) to a server via a data network using an adapter. The system may enable a telephone connected to the home telephone circuit to perform voice commands by sending audio data from the telephone to the server via the data network and the server determining the voice commands included in the audio data. Based on the voice command, the server may send an instruction to the adapter via the data network, the instruction causing the adapter to initiate a telephone call over the PSTN. Additionally, the server may send an instruction to any device associated with a user profile corresponding to the adapter. Thus, the system may enable the telephone to control a number of devices within the home using the voice commands.
