  • How to request a KUDOgov account

    External Users

    If you would like to request access to a KUDOgov account, please review the requirements below then contact your dedicated CSM or CSR and copy support@kudoway.com on the request.

    Internal Users

    Before an account can be created, it must be formally requested. KUDO’s DevOps is responsible for the entire account lifecycle, from the time that the account is provisioned and access is granted to the time that the account is disabled/removed. 

    Requesting Access: Contact DevOps and use the form that was created for this purpose by DevOps. Be prepared to provide detailed explanation, including at minimum:

    • Solid business justification for requesting access
    • Intended usage and level of access requested
    • Anticipated duration for the requested access, start and end date
    • Name and the contact information of the designated approving manager
    • Other attributes if requested by DevOps or InfoSec

    Review of the Access Request: Every access request requires (1) the approval of the requestor’s manager, and (2) the approval of the information security department, before account is created and access is provisioned.

    NOTE: The requestor and the approving manager can’t be the same individual.

    Privileged Access: KUDO DevOps enforces Role-Based-Access-Control (RBAC), hence, accounts with privileged access must be reserved for only exceptional circumstances, where elevated privileges are absolutely necessary to allow the requesters to complete their job duties.

    NOTE: Individuals requesting privileged access, must be ready to comply with multi-factor authentication requirements that will be imposed by DevOps. 

  • Getting Started with SSO

    What is SSO?

    Single sign-on (SSO) is a user authentication tool that enables users to securely access multiple applications and services using just one set of credentials. IT admins can use a single portal for controlling their employee's access. In large corporations, this is ideal because new employees that join their company often need access to multiple software services. But, having the new employee sign up for each service on their own can be cumbersome and time-consuming. SSO centralizes the process by allowing an IT admin to give access for a new employee to multiple services at once through a single login profile.

     

    How do we support SSO?

    KUDO supports SSO via SAML 2.0.

    SAML lets users sign in after successfully authenticating against your SAML identity provider and will also automatically create an account upon sign-in if one doesn't exist. The most common types of SAML implementations we support are via 3rd party vendors like OneLogin or Okta, but you can also integrate Active Directory with KUDO via SAML using ADFS.

     

    What do I need to know before I set up SSO?

    • KUDO servers (EU, COM, GOV, CA) are not connected with each other.. The SSO configuration applied to one of them, would not be applied to the other server. 
    • The user role will be automatically provisioned when a user gets invited to a session. By default, the user role is a participant, unless we receive another parameter from the SAML response. 
    • KUDO acts as the Service Provider (SP) and offers automatic user provisioning. You do not need to register as a user on KUDO. Once KUDO receives a SAML response from the Identity Provider (IdP), KUDO checks if this user exists. If the user does not exist, KUDO creates a user account automatically with the received name ID, using the default role, participant, if we do not receive another role parameter from the SAML response.

     

    Prerequisites

    1. To get started, we will need the following information:

    • Your Client Account
    • Your Organization name
    • Identity Provider (IDP)

    2. Once we set up the Organization for you in KUDO, we will be providing you with:

    • ACS URL (Consumer URL)
    • Login URL
    • Single Logout URL
    • EntityID/Audience (the name of the SAML 2.0 connector, i.e kudo-sso);

    3. Identity Provider (IDP)

    • Login to your IDP, having Admin rights;
    • Add a SAML connector
      • Add the info we've provided you at step 2.
    • Create and map the below custom parameters/fields:
      Name Value
      First Name first_name
      Last Name last_name
      Email email
      Role participant, interpreter, operator or viewer

      If not assigned a role in the IDP, KUDO will assign a participant role, by default
        • once a user gets invited to a session with another role, it will be associated with the user account. Upon login, the user can select what role is he/she planning to use
    • Save the configuration
    • Download the SAML metadata and sent it to us at support@kudoway.com

    4. Please provide us a list of the users that will be using SSO, as we need to configure the user profiles in our system to ensure they are part of the organization on our end.

    5. We will get back to you with a confirmation message. Once configured, users can sign in with SSO.

Advice and troubleshooting

  • Accessing KUDO from China

    This article covers:

    China-based participants connectivity

    What is China Relay?

     

    China-based participants connectivity

    When China-based users access internet sites that are located outside of China the traffic must pass through the Chinese Firewall. The net result is impaired connectivity and lower bandwidths.

    Other things that have an impact on the connectivity to KUDO:

    On the COM and EU servers the Chinese attendees' connectivity will be slower because of:

    • Using a VPN, the traffic is routed to one of the VPN servers, then to us, so the data transfer (audio, video, screen-sharing) is slower;
    • Chinese Firewall -  one of the many issues causing slow data transfer is that it uses Deep Packet Inspection to monitor the internet, which sometimes may cause packet loss, meaning that the requested data couldn’t make it to a user’s computer, or it arrives later;
    • Distance;
    • Limited peering capacity - this is the arrangement of traffic exchange between Internet service providers (ISPs);
    • There are other factors, but these are the most important.

    If you are having constantly multiple attendees from China on the COM or EU domains, then we can enable on request the China Relay. The China Relay is not required by clients accessing from areas not subject to internet filtering, like Hong Kong. 

     

    What is 'China Relay'?

    The China Relay is basically an infrastructure that is deployed on the Chinese data centers to improve the connectivity and video bitrates of China-based users who are connecting to KUDO meetings outside of China (COM, EU).

    NOTE:

    • Please note that there is a surcharge for the subscribed minutes from the China relay. 
    • Connectivity and media quality can depend on a number of factors, including the quality of the last mile, the traffic load on the ISP, and the performance of our data center.  As such connectivity and media quality can never be guaranteed.

     

     

     

     

     

  • My camera/microphone is not working, what can I do? (browser settings)

    You can use your camera and microphone for sites in Chrome. In order to hear and be heard, you will need to allow Chrome/Firefox/Edge. To use your hardware. 

    Steps to allow the use of camera and microphone:

    1. Open Chrome Chrome.
    2. Go to live.kudoway.com , live.kudoway.eu or  asia.kudoway.com (accessing the meeting will redirect you to the right domain, so if you are not sure, just access the meeting link). If you are just testing your connection, you will need to access:
      1. https://live.kudoway.com/test  or 
      2. https://live.kudoway.eu/test
    3. When prompted, choose Allow.
      • Allowed sites: KUDO can use your camera and microphone while on our test page. The same might be necessary when accessing a meeting.
      • Blocked sites: Some sites won't work if you block your camera or mic while you are checking them. For example, you won't be able to join a KUDO video conference.

    If you are not been prompted to allow your camera/microphone to be used,  it's most likely that you have previously not allowed them to be used on KUDO. 

    A quick fix for that is to click on the padlock icon from the URL bar, mceclip1.png 

    once done, the below screen will appear. Make sure that your Camera and Microphone are set to Allow like on the screenshot below.

     

    mceclip0.png

     

    For the Firefox browser, make sure to check this link,  where there is a similar tutorial.  If everything is ok, and the camera/microphone is still not working, make sure to check your OS settings as explained here.

  • How using VPNs affect KUDO meetings

    VPNs will always decrease your internet speed due to the processes involved when your internet traffic is tunneled through a remote server.

    This article covers:

    What is a VPN?

    How using a VPN affects internet speed?

     

    What is a VPN ?

    Simply put, a VPN stands between your computer and the internet. Imagine that you're on your computer and the cloud is the internet. Normally, your computer accesses the cloud directly  ("internet") via your internet service provider. 

    When using a VPN, your internet traffic is routed through the VPN server (which can be in a different city/country/continent), so the VPN server is accessing the internet on your behalf.

     

    How using a VPN affects internet speed?

    A VPN will always decrease your internet speed, as it adds a number of steps that were not initially present in your connection to KUDO. The main reasons for a decrease in internet speed are:

    Latency

    Latency represents the amount of time between a user action and the resulting response. For example, the delay between when a meeting attendee clicks on a different language option during a meeting, and the time the audio reaches the attendee. 

    mceclip0.png

    latency.pngmceclip1.png

     

    The main cause of latency when using a VPN is the physical distance between locations where the data is accessed and delivered. When a user makes an Internet request, the farther the request and subsequent response have to travel, the more delay the meeting attendee will experience. 

    Suppose Cecilia is based in Spain, and she uses a VPN server from Greece to connect to one of the meetings. Every time her computer communicates over the internet, it must send the request all the way to Greece, and then her VPN service will decrypt the request and forward it to KUDO. KUDO will then send a response back to the VPN server in Greece, and finally, the VPN will encrypt this response and send it to Cecilia in Spain.

     

    Encryption

    Different VPN's might be using different level of encryption and different implementation processes. The encryption/decryption process takes time, and it could add noticeable latency to your KUDO meeting.

     

    VPN Server Load

    When there are too many users connected to one VPN server (VPN customers choosing the same VPN server location as you do), the connection speed drops. 

    Suppose Nils is connecting to a VPN server at the same time as 1,000 other users, and the server only has enough capacity to handle 300 requests at a time. The server will likely get overloaded and start queueing or dropping requests, slowing load times for Nils and many of the VPN’s other users. This experience is especially common with free and discount VPN services.

     

  • Screen sharing on Mac

    If you are running macOS Catalina or a later version, you must grant access to the Screen Recording Permission in order to share your screen during a KUDO call.

     

    How to enable screen sharing for KUDO

     

    1. When you first join a KUDO meeting on macOS, you’ll be asked to enable the Screen Recording permission for your browser.

     

    This can also be done manually from the Apple menu  > System Preferences, click Security & Privacy.

    2. Select the Privacy tab, then Screen Recording;

    3. Select the tickbox next to the browser you use to allow it to record your screen.

     

    4. In order for the changes to take effect, you will need to quit the selected browser.

    5. Open your browser and rejoin your video call. You should be able to screen share.

     

     

     

     

     

     

     

     

  • KUDO bandwidth requirements

    This article covers the bandwidth requirements for using KUDO. In order to check the WebRTC bandwidth output of your network, you can take one of these tests:

    General Meeting Video Quality

    During a KUDO meeting, the video quality dynamically adjusts based on the strength of a user's network bandwidth. This is done by sending feedback data packets to the people on the Floor (participants that have shared their video) informing them about your network bandwidth and what video quality it's able to support. 

    The video bit-rate of the participants sharing their camera will be automatically adjusted based on the other participants' network conditions. The network stability and speed of the latter ones directly affect the quality of the video that will be shown on the Floor.

     

    Note: By default, when creating a meeting the settings video and audio settings are set to Adaptive. While these can be changed, we suggest keeping them as such, for a better overall experience.

     

    Bandwidth requirements for different meeting qualities

    For various resolutions and quality combinations, the bandwidth requirements are outlined below.

    • Excellent - None or imperceptible impairments in media
    • Acceptable - Some impairments in media, leading to some momentary disruptions

  • Audio Echo In A Meeting

    The echo is a repetition of the sound that arrives at the listener. If you hear audio echo or audio feedback during your meeting, then this might be caused by:

    1. Multiple devices with active audio in the same room;

    2. Not using a headset;

     

    Multiple devices with active audio in the same room

    If you are in a room where multiple devices connected to the same meeting have their microphone enabled, then some microphones might channel your audio back, hearing it as an echo in the meeting. 

    To avoid this, if you encounter yourself in such a situation, make sure that you are not close to the other participants, or one of you has the microphone on mute, while the other one is speaking. 

     

    Not using a headset

    When not using a headset, and relying on your PC speakers and microphone, changing the sound settings on your computer can help minimize echo issues. Try the following before that:

    • Lower your speaker volume to reduce the echo;
    • If your microphone or audio device is near a wall or other reflective surface that does not absorb sound, consider moving the microphone or changing its direction away from the reflective surface to reduce potential echoes;
    • If you’re using your webcam’s microphone or your computer speakers, try using a different audio device such as a headset, handset, or standard microphone;
    • If possible, try placing the microphone as far away as possible from the computer speakers because the audio output from the speakers may feed into the microphone and produce echoes.
    • If you are using a laptop with an integrated sound card that supports Microphone Boost (Noise Suppression/Ambient Noise reduction), disabling Microphone Boost can help you isolate the issue: 

     

    On Windows 

    • Click Start, and then click Control Panel.

    • In Control Panel, click Hardware and Sound, and then click Sound.

    • In the Sound dialog box, on the Recording tab, select your microphone, and then click Properties.

    • In the Microphone Properties dialog box, on the Levels tab, uncheck the Microphone Boost (Noise Suppression/Ambient Noise reduction)checkbox (if available);

    On Mac

    • In System Preferences in your Launchpad, click on the Sound icon;
    • In the Input tab select the microphone that you are using;
    • Uncheck the Ambient Noise reduction checkbox;

     

    Other Tips:

    Generally, if you are hearing echo, it means that there is a device out there that is channeling your audio back.

    To isolate the attendee:  

    • The host can mute the attendees one at a time;
    • The attendee can mute him/herself;

    The source of echo can also be from: 

    • Speakers that are too loud;
    • Echo cancellation has failed (device or performance issue);
    • A bad microphone;
