Abstract: A system capable of connecting a device to a Public Switched Telephone Network (PSTN) using an adapter. The adapter may receive caller identification from the PSTN during a second ringing signal and may send notifications to remote server(s) indicating the caller identification. The remote server(s) may use the caller identification to enable additional functionality in a speech processing system. For example, the remote server(s) may identify contact information corresponding to the caller identification, may determine information about the contact, such as recent meetings, communications, or the like, and may output the information when announcing the incoming call. In addition, the remote server(s) may compare the caller identification to a database of spam and indicate that the incoming call is possible spam.

Abstract: A system capable of connecting a device to a wired communication network (e.g., Public Switched Telephone Network (PSTN)) using an adapter. During a telephone call using the PSTN, the adapter may mix two or more audio streams to enable multiple devices to join the telephone call. However, the adapter has limited resources. If the adapter receives a request from an additional device to join the call, the adapter may send a notification that indicates a maximum number of endpoints has been reached. To enable audio mixing for additional devices, the system may send multiple audio streams to a communication server to be mixed and the mixed audio stream are sent to the adapter to be output using the PSTN. The communication server may receive the audio streams from the adapter or directly from the devices.

Abstract: A system capable of connecting a device to a Public Switched Telephone Network (PSTN) using an adapter. During a telephone call using the PSTN, the adapter may receive an incoming call from the PSTN and send caller identification to remote server(s). The remote server(s) may determine an identity of a first user currently on the telephone call and determine that the incoming call is directed to a second user. Based on the caller identification, the remote server(s) may send a notification to the second user indicating the incoming call. Alternatively, the remote server(s) may interrupt the current telephone call to announce the incoming call. For example, if a parent is on the telephone when an incoming call for a child is received, the remote server(s) may send a text message to the child without interrupting the current telephone call.
