Examples are disclosed for placing an outbound telephony call using a mobile telephony device as a proxy to make the call on behalf of a smart speaker device. At a communications server, it is determined whether a mobile telephony device is in proximity of a smart speaker device. When the mobile telephony device is in proximity of a smart speaker device and attempts to place a telephony call, the communications server establishes a communications link between the communications server and the smart speaker device. The communications server may then dial the telephone number sent by the mobile telephony device and establish a communications link between the communications server and a device associated with the dialed telephone number. The communications server may then join the communications link between the communications server and the smart speaker device with the communications link between the communications server and a device associated with the dialed telephone number to create a communications session.
