In some implementations, a mobile computing device may participate in the calibration of an output signal of a media device. This calibration process includes storing device-specific calibration data which is related to properties of a light sensor of the mobile device. The mobile device then detects of properties of light emitted by the display device during a presentation to obtain sensor values related to light emitted by the display device during the presentation. The calibration process may also ensure that the mobile device is proximate to the display device prior to obtaining the sensor values. The collected sensor values are adjusted using device-specific calibration data stored to the mobile device to normalize the sensor values relative to a baseline. These normalized sensor values are sent to the media device for use in adjusting the output signal based on the normalized sensor values.

Systems and methods for establishing call connection in response to user action, the method including receiving a first user action from a user associated with making a call connection, wherein the first user action comprises any of copying at least part of a phone number, pasting at least part of the phone number, or inputting at least part of the phone number. The method also includes determining one or more call recipients based on the first user action. The method also includes establishing one or more silent call connections based on the determined one or more call recipients, wherein each of the one or more silent call connections comprises a call connection with a predetermined parameter so that there are no incoming call indicators on one or more devices associated with the one or more call recipients.

In one embodiment, the method of processing telephony sessions includes: communicating with an application server using an application layer protocol; processing telephony instructions with a call router; and creating call router resources accessible through a call router Application Programming Interface (API). In another embodiment, the system for processing telephony sessions includes: a call router, a URI for an application server, a telephony instruction executed by the call router, and a call router API resource.

Methods are provided for providing a unified communication history of a multi-modal communication. In one aspect, a method includes receiving a plurality of event logs related to the multi-modal communication. The multi-modal communication comprises a first communication modality and a second communication modality. The method includes aggregating the one or more events from the event logs as a plurality of aggregated events and resolving an identity of each user from among the plurality of users in the plurality of aggregated events. The method includes storing the aggregated events into a communication history of the multi-modal communication. Systems and machine-readable media are also provided.

A system is provided for automated configuration of a connection interface between a headset device (e.g., a headset base) and a telephone (e.g., desktop phone). The system includes configuration circuitry designed to automatically perform a sequential analysis of multiple interface configuration options for the connection interface between the headset device and telephone. The analysis of each respective interface configuration option includes (a) accessing stored configuration information defining predefined switch positions for an array of controllable switches (e.g., optical switches) corresponding with the respective interface configuration option, (b) set the array of switches to the predefined switch positions specified by the accessed configuration information, and (c) performing a signal analysis to analyze electrical signals on the connection interface. The configuration circuitry may then select a best interface configuration option based on the signal analyses, and set the switches to the predefined switch positions corresponding with the selected best interface configuration option.

A captioning relay for captioning hearing user (HU) voice signals comprising a plurality of separate captioning resources and a captioning administrator module that receives HU voice signal segments corresponding to a plurality of separate ongoing calls between HUs and AUs and provides the voice signal segments in a first in, first out order to the captioning resources, the administrator module providing each voice signal segment from each call to any one of the captioning resources to be captioned without regard to which captioning resource captioned prior voice signal segments generated during the call and, the administrator module further receiving caption segments back from the captioning resources and providing those captioning segments to AU devices associated with the calls that generated corresponding HU voice signal segments, and wherein the number of captioning resources is less than the number of ongoing calls.

A method may include obtaining a first audio signal including first speech originating at a remote device during a communication session between the remote device and a communication device and obtaining a second audio signal including second speech originating at the communication device during the communication session between the remote device and the communication device. The method may also include obtaining a characteristic of the communication session from one or more of: the first audio signal, the second audio signal, and settings of the communication device and determining a hearing level of a user of the communication device using the characteristic of the communication session.

Methods and apparatuses for managing accessibility features for mobile devices are described. Accessibility features may facilitate a user to interface with his/her mobile device and may be referred to as user-interface parameters configured to generate output or to receive input. The mobile device may generate an accessibility icon corresponding to one or more user-interface parameters selected by the user. The mobile device may also store a set of values provided by the user, where individual values correspond to individual user-interface parameters. Subsequently, the mobile device displays the accessibility icon such that the user may actuate the accessibility icon to adjust the user-interface parameters based on the values. Further, the user-interface parameters may be adjusted to more than one set of values. The mobile device may generate multiple accessibility icons that each correspond to different collections of the user-interface parameters.

A system and method for use with an assisted user's communication device that includes a display. The method includes providing a user communication device including a processor that is programmed to perform the step of, upon disconnection of an emergency call to a hearing user in which a captioning service has provided text transcription of voice messages from the hearing user, maintaining a link to the captioning service for a predetermined period of time. The processor also is programmed to perform the step of recognizing the call as an emergency call upon placement of the call, and the captioning service is automatically initiated upon the processor performing that recognition.

Systems and methods for establishing call connection in response to user action, the method including receiving a first user action from a user associated with making a call connection, wherein the first user action comprises any of copying at least part of a phone number, pasting at least part of the phone number, or inputting at least part of the phone number. The method also includes determining one or more call recipients based on the first user action. The method also includes establishing one or more silent call connections based on the determined one or more call recipients, wherein each of the one or more silent call connections comprises a call connection with a predetermined parameter so that there are no incoming call indicators on one or more devices associated with the one or more call recipients.
