Briefly, claimed subject matter may relate to a caller verification system having a signaling resource for forming a communications channel for a call placed between a call source and a call destination. The signaling resource may generate a call setup record having parameters relevant to the formed communications channel. The call verification system may additionally include a call verification device that provides call parameters to the signaling resource and receives from the signaling resource, an indication of a match between the provided call parameters and the parameters of the call setup record.

A redirection and messaging system receives telephony information identifying a caller and call context from a telephony system. The system selects one of a plurality of messaging operators based on the call context, optionally sends an introductory message to the caller via a messaging service, and generates a message interface for the selected message operator. The message interface includes the caller and call context and any messages sent between the caller and the selected message operator, with an input interface allowing the selected message operator to input and send messages to the caller.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for receiving, from a computer system, a request comprising a phone number, identifying a primary channel and one or more secondary channels based on, at least in part, respective performance data of the primary and secondary channels, sending a first message comprising a first text string via the primary channel to a destination device associated with the phone number, after sending the first message, determining that a conversion event for the message and the primary channel did not occur within a specified time period, and based on the determining, sending a second message comprising the first text string via a particular secondary channel to the destination device.

A message notification indicates a message has been retrieved and/or read. The message notification may be sent to any destination, such as a sender's device. When the sender's device receives the message notification, an icon or other graphical indicator may be displayed to indicate the message has been retrieved and/or read.

When a call is transferred from one telephone set to another telephone set, it is possible to enable a user of a transfer destination telephone set to recognize from whom a call came. A first telephone set (11) makes a call to another person. A second telephone set (12) is a telephone set to which the call is transferred from the first telephone set (11). Voice data acquisition means (13) acquires voice data of the other person on the call made by the first telephone set (11). Voice recognition means (14) performs voice recognition on the voice data acquired by the voice data acquisition means (13) and generates text data. Transfer destination text display means (15) displays the text data generated by the voice data recognition means (14) for a user of the second telephone set (12).

Automated message generation to a subject matter expert in response to a phone call is provided. A computing device receives a message identifying a telephone call that terminates at the computing device based on a destination number. Caller identification information, comprising at least a calling device number, is determined based on the message. An item identifier (ID) associated with the telephone call is determined. Information about an item that corresponds to the item ID is accessed. The information is sent to the calling device number. A message that includes the calling device number and item information that identifies the item is sent to a contact device.
