An audio receiver for a converged portable radio (LMR/LTE radio) is provided with improved audio management. The converged device is managed by two different processors (BP/AP) and includes a selectable user setting for selecting either an LMR audio mode or an LTE audio mode (or both). Power up timing differences between the two processors is managed through a smart audio switch mechanism which includes AP control logic for selectively enabling and disabling an AP audio switch in response to operational status of both (AP/BP) processors during power up. The smart audio switch system further includes BP control logic for selectively enabling and disabling a BP audio switch in response to the operational status of the processors. Audio is played out at a single speaker. Both LTE audio and LMR audio can be mixed for a predetermined time during power up until the user selected audio mode has been established.

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.

This application discloses a method for establishing a call connection, a first terminal, a server, and a storage medium. The method includes: obtaining, by a first terminal, a second vocoder list of a second terminal, the second vocoder list including vocoders supported by the second terminal and with corresponding priorities; determining, by the first terminal, a first vocoder with the highest priority among vocoders that exist in both a first vocoder list of the first terminal and the second vocoder list, the first vocoder list including vocoders supported by the first terminal and with corresponding priorities, and the priorities of the vocoders being positively correlated with audio frequencies in encoding and decoding of the vocoders; and requesting, by the first terminal by using the first vocoder, to establish a first call connection to the second terminal.

Devices, systems and methods are provided to support a party call with auto-joining function in a communication system for a distributed transport system that employs VoIP technology. A VoIP unit or end point acts as a conference bridge between an operator extension and other end points. A first end point makes a SIP call to the operator and multicasts a mix of its send audio and the received operator audio. Other end points first check for multicast traffic being received before making a SIP call to the operator and, if so, play out the received audio over its speaker and multicast its send audio. The end point initiating the call mixes this subsequent stream into a stream to the operator, effectively acting as the conference bridge to the operator. The other end points are responsible for mixing received multicast streams for their local speaker.

A system and method embodying the invention utilizes voice applications that are performed by voice applications agents resident on user local devices to deliver messages to the users. The voice applications can also be used to collect information from the users. Also, voice applications can be used to allow users to purchase goods and services. Voice applications for these purposes could be customized to take into account the individual characteristics of the users.

Methods and apparatus implementing a telephony terminal for connecting a telephone to a data network. In one implementation, a telephony system includes: a phone connection for connecting to a telephone; a network connection for connecting to a network; and a controller connected to said phone connection and to said network connection; wherein said controller provides a phone service for processing information for said phone connection, said controller provides a network service for processing information for said network connection, and said controller provides a network voice service for converting information to and from a network voice format.

An example method of operating a network may include determining whether a flow is to be added to the network based on: a flow type of the flow, a link condition of the flow, and for each possible combination of flow type and link condition out of multiple flow types and multiple link conditions, the number of flows currently carried on the network that correspond to the respective combination.

A field device includes components to communicate with a control and/or asset management system of a process control system or with other field devices using any of several different communication protocols such as several different internet protocol (IP) protocols. This architecture allows for a single version of a field device to be provided in automation or plant control systems that use any of these communication protocols, thus saving on inventory and product development costs. Moreover, the multi-protocol field device or a system using the multi-protocol field device can manage the asset (read and write parameterized data from and to the asset) using one protocol while at the same time communicating real-time process/factory automation information using a second and different protocol. Moreover, the field device may be able to communicate to other devices including other field devices and host devices using both of these protocols or other protocols for different purposes.

As a user interacts with a voice application, a history of the prompts played to the user and the users responses are displayed to the user. The displayed prompts and displayed responses could be summaries of the prompts and responses, or they could be full transcriptions of the prompts and responses. A user may be able to select a prompt or response in the history to return to a certain point in the voice application. It may be possible for a user to save a history of the interactions that occurred when a voice application was performed, and to recall the history to continue on from a selected location in the history.
