The method includes that: a second terminal device may send an audio output request to a first terminal device, and a user may operate the first terminal device or an audio output device connected to the first terminal device, to trigger the second terminal device to obtain audio data corresponding to the audio output request. When the audio output device is a wireless audio output device, the second terminal device may establish a communication link with the wireless audio output device, to control the wireless audio output device to output a first audio signal corresponding to the audio data; and when the audio output device is a wired audio output device, the first terminal device may obtain audio data from the second terminal device, to control the audio output device connected to the first terminal device to output a first audio signal corresponding to the audio data.

A method may include obtaining an indicator that a first device is in a location of a second device and in response to obtaining the indicator, sending a redirect request to a communication service provider of the first device to direct, to the second device, incoming communication requests handled by the communication service provider that are directed to the first device. The method may further include after sending the redirect request and after a communication request to a communication session is directed to the first device, obtaining, at the second device, a communication indication to participate in the communication session. The method may further include directing audio of the communication session to a transcription system and obtaining, at the second device, the transcription of the audio from the transcription system. The method may also include presenting, by the second device, the audio and the transcription.

Techniques and systems for receiving and using a customization file are provided, including a computing device, a method, or a computer-program product. For example, a method may include receiving a customization file that includes customized content for customizing a communication interface overlay. The method may further include accessing native application code and executing the native application code to run a native application. The method may further include accessing a compiled set of code that is separate from the native application code. The compiled set of code is accessible by the native application code. The method may further include executing the compiled set of code, wherein a default file of the compiled set of code provides a native communication interface overlay, wherein the native communication interface overlay is overlaid over a graphical interface of the native application, and wherein the native communication interface overlay allows communication with a resource of a third-party. The method may further include executing the received customization file, wherein executing the received customization file customizes the compiled set of code, and wherein the customized compiled set of code customizes the native communication interface overlay to provide a customized communication interface overlay.

Methods and systems are described for coordinating multiple calls across multiple devices. The system includes a communication interface configured to be paired with multiple mobile devices while maintaining concurrent communication with the multiple mobile devices. A controller is configured to connect a microphone and a speaker to the first mobile device via the communication interface to transmit and receive audio in a hands-free mode in response to detecting the first call at the first mobile device. The controller is configured to output a first prompt for selection of whether to continue the first call through the communication interface in the hands-free mode in response to detecting the second call at the second mobile device. The controller is configured to disconnect the microphone and the speaker from the first mobile device in response to receiving a first input indicating a selection of exiting the hands-free mode for the first call.

A hands-free apparatus includes a memory and a hardware processor coupled to the memory. The hardware processor is configured to: connect to a mobile phone to enable a hands-free telephone conversation; receive at least one data of outgoing call history data, incoming call history data, missed call history data, and phonebook data stored in the mobile phone; and execute synchronization permission checking processing to check whether transfer of the at least one data is permitted in the mobile phone before receiving the at least one data from the mobile phone.

A hands-free apparatus includes a memory, and a hardware processor coupled to the memory. The hardware processor is configured to: connect to a plurality of mobile phones to enable a hands-free telephone conversation; and receive at least one data among outgoing call history data, incoming call history data, missed call history data, and phonebook data stored in one mobile phone among the plurality of mobile phones. The hardware processor is configured to, when receiving the data from the one mobile phone, execute reception of the data from a second mobile phone at a prescribed timing.

A voice call method, device and system, the method including establishing, by a first device, a Bluetooth link to a second device, receiving, by the first device, call request information sent by a third device, sending the call request information to a second device through the Bluetooth link, sending, by the first device in response to an answer command from the second device, the answer command to the third device, establishing, by the first device, a call with the third device, sending a downlink audio signal received from the third device to the second device, or sending and uplink audio signal received from the second device to the third device, and converting, by the first device, in response to a sound channel switching command and receiving a downlink audio signal sent by the third device, the downlink audio signal into a sound signal, and playing the sound signal.

A hands-free device is disclosed, in which a memory and a hardware processor connected to the memory are included. The hardware processor establishes a connection with a mobile phone using a hands-free communication protocol for making a hands-free call. The hardware processor establishes a connection with the mobile phone using a data transfer protocol for transferring phone data about a phone to receive the phone data transferred from the mobile phone, and stores the phone data into the memory. When a phone communication state of the mobile phone is transitioned while the phone data is being transferred, the hardware processor executes transfer control in accordance with transfer criteria, each depending on a type of the phone data being transferred and the phone communication state after the transition.

A method may include obtaining an indicator that a first device is in a location of a second device and in response to obtaining the indicator, sending a redirect request to a communication service provider of the first device to direct, to the second device, incoming communication requests handled by the communication service provider that are directed to the first device. The method may further include after sending the redirect request and after a communication request to a communication session is directed to the first device, obtaining, at the second device, a communication indication to participate in the communication session. The method may further include directing audio of the communication session to a transcription system and obtaining, at the second device, the transcription of the audio from the transcription system. The method may also include presenting, by the second device, the audio and the transcription.
