Terminology

Term	Description
Agent	The end user of the LiveVox Agent Desktop.
Agent Desktop	The customizable agent view that displays customer information, Automatic Call Distributor (ACD) tools, and disposition codes. Different service types, such as HCI and Preview, can have different Agent Desktops. The Unified Agent Desktop (UAD) is an Agent Desktop that, when configured, expands to display the agent pane and additional widgets within the same window.
Bandwidth	The amount of data that can be transmitted in a fixed amount of time.
Clicker HCI Agent	The agent who is signed in to the Human Call Initiator (HCI) service to manually select and launch calls from the HCI Agent Desktop. Clicker Agents do not use an audio connection. No additional bandwidth is required for Clicker HCI Agents.
Codec	A device or a computer program for encoding or decoding a digital data stream or signal.
Datagram Transport Layer Security (DTLS) Protocol	A communications protocol for protecting data privacy and preventing eavesdropping and tampering.
Human Call Initiator (HCI) Service	A service in which an agent (that is, a Clicker Agent) manually launches a call. If a customer answers the call, the call is routed to the closest agent, who speaks with the customer.
Real-time Transport Protocol (RTP)	A network protocol for delivering audio and video over IP networks.
Request for Comments  (RFC)	A formal document from the Internet Engineering Task Force (IETF) that is the result of committee drafting and subsequent review by interested parties.
Transport Layer Security (TLS) Protocol	A common security protocol for facilitating privacy and data security for communications over the Internet.
User	The end user of the LiveVox Portal (LVP), who can be assigned different roles with distinct permissions. For more information, see the User Roles and Permissions section of the User Hub.
Voice over Internet Protocol (VoIP)	A methodology and group of technologies for delivering voice communications and multimedia sessions over Internet Protocol (IP) networks.
Web Real-Time Communication (WebRTC)	A method for delivering voice and other forms of communication that are embedded directly on a web page. The technologies behind WebRTC are implemented as an open web standard and available as regular JavaScript APIs in all major browsers. For native clients, such as Android and iOS applications, a library is available that provides the same functionality. The WebRTC project is open-source and supported by Apple, Google, Microsoft, and Mozilla, among others.

Minimum Agent Requirements

LiveVox supports the following agent connectivity methods:

• Agent Desktop Native (ADN)
• Agent Desktop (connecting to the Agent Desktop by using a web browser)
• Web Audio
• LiveVox Communicator (LVC)
• SIP Trunk
• PSTN
• Mobile Access to Agent Desktop

Agent Desktop Native (ADN)

Agent Desktop Native (ADN) is an installable LiveVox application that uses the open-source WebRTC framework and is specifically designed to consolidate the agent's experience in a single view. It offers the following benefits:

• Ease of Use 
  
  • Easy to install at any location with a public Internet connection.
  • Software only—no additional licensing cost and specialized equipment required.
  • No setup overhead—the application is pre-configured and fully customizable.

  • Flexible connectivity with no browser dependency.
    
  • Uses the advanced audio codec Opus for improved audio quality and control.

• Feature Rich  
  
  • Offers access to new features and enhancements that might not be available with other connectivity options. That is, ADN supports Screen Recording and MS .Net integration features.

ADN allows you to use third-party resources that might increase the overall resource consumption. Remember to consider this when estimating bandwidth and system requirements. 

Agent Desktop 

You can access the LiveVox Agent Desktop through a web browser using a URL. 

Check with your manager for the URL that is specific to your organization (for example, https://portal.na3.livevox.com/<Client Code>/AgentLogin).

Web Audio

Web Audio is a non-proprietary agent connectivity method over supported web browsers using the open-source WebRTC framework.

• Ease of Use 
  
  • Works natively with supported web browsers; therefore no installation, extensions, or add-ons are required.
  • Easy to access at any location with a public Internet connection.
  • Software only—no additional licensing cost and specialized equipment required.
  • No setup overhead—it is a web application.
  • Native encryption using industry standards for secure connections out of the box.
  • Uses the advanced audio codec Opus for improved audio quality and control.
• Feature Rich 
  • Is browser-dependent.
  • Does not support Screen Recording and MS .Net integration features.

LiveVox Communicator (LVC)

LiveVox Communicator (LVC) is an installable LiveVox application (softphone) that provides voice access to the LiveVox platform. It is a legacy connectivity method that has been superseded by ADN.

• Ease of Use 
  • Easy to install at any location with a public Internet connection.
  • Software only—no additional licensing cost and specialized equipment required.
  • No setup overhead—the application is pre-configured.
  • Encryption using industry standards for secure connections out of the box.
  • Flexible connectivity with no browser dependency.
  • Not integrated with the Agent Desktop; therefore, does not offer a consolidated agent experience in a single view. The agent is required to use two separate applications: LVC for voice and a web browser for Agent Desktop.
  • Not compatible with Microsoft RDS or Citrix-published applications.
  • Does not support Mac or Linux OS.
  • Opus codec is not available.
• Feature Rich 
  • Does not support Screen Recording or MS .NET integration features.

SIP Trunk

If required, LiveVox can support a SIP trunk connection. A SIP trunk is a direct connection between an in-house telephony system and the LiveVox platform.

• Ease of Use 
  
  • Significant setup, configuration, and maintenance overhead.
  • Requires experienced resources that are knowledgeable about your network and SIP infrastructure.
  • Is dependent on the existing telephony system's capabilities for integration with LiveVox.
  • Not integrated with the Agent Desktop; therefore, does not offer a consolidated agent experience in a single view.

• Feature Rich 
  • Does not support Screen Recording or MS .NET integration features.

Due to a large number of vendors, versions, add-ons, and custom deployments for many of these systems, LiveVox is unable to provide configuration documentation.

PSTN

If required, LiveVox can support agent connectivity through the Public Switched Telephone Network (PSTN). LiveVox will provide a local number that the agents can use to establish the voice session through their local lines. This is typically used as a backup solution when an Internet issue occurs. 

• Ease of Use 
  • Voice traffic is not routed over the Internet; this requires the agents to have a connection through the PSTN.

  • An additional charge is incurred for each minute of connection.

    

    For information about pricing, contact your Account Manager.

  • Not integrated with the Agent Desktop; therefore, does not offer a consolidated agent experience in a single view. The agent is required to use a web browser or ADN for Agent Desktop and a desk phone for voice. 

• Feature Rich 
  • If ADN is used, access to new features and enhancements that may not be available with other connectivity options is available. That is, ADN supports Screen Recording and MS .Net integration features.
  •  If a web browser is used, Screen Recording and MS .Net integration features are not supported.

Mobile Access to Agent Desktop

LiveVox Agent Desktop supports touchscreen functionality for mobile devices.

Screen Recording Requirements

You need ADN to use the Screen Recording feature. The quality of the recording depends on multiple factors such as bit rate, frame rate, and the number of screens.

Recommendations

For good-quality screen recordings, LiveVox recommends the following settings.

Bit rate, frame rate, and the number of screens have a direct impact on the bandwidth usage of ADN.

Examples

A chart representing the bandwidth usage of Screen Recording with different configurations for one screen is as follows.

A chart representing the bandwidth usage of Screen Recording with different configurations for two screens is as follows.

Impact of ADN 7.3.0 on Virtual Environments

ADN and its functionalities are available in virtual environments such as Microsoft RDP and Citrix. However, it is important to verify the impact of CPU usage on the hosts, especially if you are using Screen Recording, which is a resource-intensive process. Some of the results from our test lab for different configurations are as follows.

Frequently Asked Questions

• Which encryption protocol do you use for communication channels? 
  TLS1.2

• What are your headset requirements?
  LiveVox can work with any headset. However, we recommend that you use a model that includes the following features at a minimum:

  • USB 2.0+ connection

  • No wireless connectivity

  • Stereo audio

  • Full coverage of both ears (over-the-ear headphones)

  • Noise cancelation

  • 32000 Hz+ sampling rate

  • 16-bit digital audio bit depth

  • Automatic gain control

  • Hardware muting

• What are the requirements for our server infrastructure to run your product at sites in multiple geographical locations (both domestic and international)?
  Some ports, IPs, and domains will need to be whitelisted on your network. To help accommodate that, our requirement is that we go through the VoIP Implementation process to perform proper testing with your network. This is to ensure that your network is capable of reaching the LiveVox servers with minimum latency and to ensure that the audio quality is high.
