Patent attributes
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.
