VoIP Troubleshooting

Basics

  • Do you have a headset with a mic hooked up to your computer? Are you sure it works?
  • Did you go through the mic setup process?
  • Do you have a good browser? We recommend Firefox or Chrome. We’ve already seen a couple instances where upgrading the browser fixed the problem.

Adjusting Volume

There are 3 ways to adjust your mic volume when using Vyew.

    • In Vyew: Click on the microphone icon, next to your name in the userlist near the top right of Vyew. Adjust the volume slider or mute.
    • In Flash Settings: Right click anywhere on an open Vyew Room, click on Settings…. In the Adobe Flash Player Settings box, click on the Microphone tab. Adjust the slider, using the green volume meter, then click Close.

    • In Mac OSX: In Finder, click Applications -> System Preferences -> Sound -> Input tab. Select the correct input device and adjust the Input Volume.

I Can’t Broadcast Sound

This usually means your microphone device is not properly selected.

  1. Bring up the Adobe Flash Settings box by right clicking (control+click on Mac) anywhere inside a Vyew Room and selecting Settings….flash mic settings
  2. Go to the Microphone tab.
  3. Do you see any Microphone device in the dropdown menu?
    • YES: Continue to step 5.
    • NO: Your sound card is not properly installed or drivers for the mic device are not setup. Fixing this is beyond the scope of this document. Try googling it or ask your local techie.
  4. There is a sound level indicator (the vertical green bar in the example above) which should be jumping up and down when you speak into your mic. If not, click to expand the Microphone dropdown menu. Is there more than one device listed?
    • YES: Try selecting a different mic device as you talk into your mic to see if the sound level moves. If you find the correct one and you see the sound level moving, you are done. Vyew VOIP will work now. If not, continue to step 6.
    • NO: Continue to step 6.
  5. The correct mic devices are probably not selected by your sound card/driver. Take note of the Mic device that initially appears in the Microphone dropdown in the Flash Player Settings, then…
    • For Windows…
        1. In Windows XP, go to Start button -> Control Panel -> Sound and Audio Devices -> Audio tab -> Sound Recording section.
        2. In Windows 7, go to Start button -> Control Panel -> Sound -> Recording tab.
        3. Verify which device is selected as default. It should match what was selected in the Flash Player Settings.
      Win XP and Flash audio devices match
      Win XP and Flash audio devices match
    • For Mac…
      1. From Finder, click Applications -> System Preferences -> Sound -> Input tab.
      2. Choose the device that was selected in the Flash Player Settings. Make sure it’s Input Volume is maximized.
    • For Linux…
      • Similar to Windows and Mac, verify that the default input device for your system is the same one that was primarily selected by Flash. Make sure nothing is muted and volume levels are at or close to 100%.
  6. Try a different mic/headset device, maybe there is problem with your mic device.
  7. After changing/checking all the above settings, try restarting your browser.
  8. Still doesn’t work? Please contact Vyew Supportand convey this information:
    • What were the results of each of the above tests?
    • What is your operating system and browser/version?
    • What type of sound card do you have? What microphone device is selected?
    • Does your mic work for any other software online? Like skype?

I Can’t Hear Any Sound

  • Try your speakers on a YouTube video. Do they work?
    • YES: If your speakers work with YouTube, they should also work with Vyew. Please contact support if this is the case.
    • NO: Make sure you speakers are on and plugged in to the right jack. Make sure your computer sound card is recognized. Fixing this issue is beyond the scope of this document, you’ll need to contact someone who knows how to fix it.

My Sound is Choppy or Drops Out

There could be a couple of reasons for choppy sound:

  • For the person talking, their computer and/or bandwidth is too slow.
  • For the person talking, their microphone may be broken or have sensitivity issues.
  • For the person listening, their computer and/or bandwidth is too slow.
  • Internet congestion.
  • Something is wrong with Vyew VoIP servers.

Let’s try to isolate the problem.

  • Which computer? Try getting a 3rd person in the room. Is it choppy for all listeners? If so, there’s a good chance its a problem with the computer of the person talking.
  • Check the Microphone: Go to the browser test page, perform the Microphone Test, and see if it’s choppy during recording/playback. Try a different mic– your current may be broken, or may be too sensitive and overloading the signal. Try adjusting the mic input in your operating system’s sound mixer or in the Adobe Flash Player Settings dialog box.
  • Check the Bandwidth: Try playing a YouTube video, is it choppy on playback? If so, your bandwidth is suffering. If you’re on WiFi, try a wired connection. If broadcasting, try reducing your broadcast quality.
  • Check the CPU:
    • On Windows…
      • Click the Start button (then Run… in XP), type “taskmgr” and press ENTER.
      • Click on the Performancetab in the Task Manager.
        Task Manager
        Windows XP Task Manager
    • On Mac…
      • In Finder, open Applications -> Utilities -> Activity Monitor, then click on the CPU tab.
    • The CPU Usage graph shows how hard the CPU is working. While keeping this window open, try speaking with someone in a Vyew room over VoIP. If the CPU usage graph spikes to 100% during speaking or listening, then this means your computer is too slow to handle it.

How to Use VoIP (Talk button)


The VOIP (Push To Talk Button) utilizes Adobe Flash’s built-in audio codec to send audio from your computer mic to the headset of anyone in your meeting room.

Allowing Flash to access your Microphone

The first time you use VoIP, you will be asked to allow Flash access to your mic. See this troubleshooting guide for more information.

Duplex Audio

Up to 4 people can use their mics at the same time, but everyone in your room will be able to hear. Anyone else will have to wait for one person to turn off their mic before they will be able to use theirs.

Quality Settings

If some of your meeting attendees experience audio drop outs, garbled sound, or distortion, try stopping your mic, changing to a lower quality setting, then resuming.

Approximate bandwidth usage for VoIP:

  • Low – 10-20 Kbps
  • Regular – 15-30 Kbps
  • High – 25-45 Kbps

Setting Up Your Mic and Webcam

Headset

Vyew's VoIP (Voice over IP) system broadcasts your voice to other users through a headset mic plugged into your computer.A headset is recommended. One person using speakers or "speakerphone mode" can frequently cause echoing for everyone in the room.

  • The video conferencing system built in to Vyew uses a standard webcam.

First test your settings

  • Make sure your headset and webcam are plugged in, then go to Vyew’s browser test page. There, your browser will be tested for Adobe Flash 10.2+, which is required.
  • Did the Flash test fail? Don’t see the mic and webcam tests? You must install Flash from Adobe’s web site. It’s a good idea to reboot your computer after doing so.
  • If you have Flash installed, you will see two tests, Test Microphone and Test WebCam. Click those and you will be prompted to record a small portion of audio or video, and it will be played back to you.

If the Microphone and Webcam Test worked, you are ready use the Webcam and VOIP in a Vyew Meeting.

Communication Methods – Overview

newRoomCommunicationSidepodMinimizedIf the communications side bar is minimized, click anywhere on it to open.

Four Methods of Communication

  • webcamButtonWebcam – Up to 4 users can simultaneously broadcast their webcam image to everyone in the room.
  • talkButtonBuilt-in VoIP (Voice over IP) – Up to 4 users can simultaneously broadcast their headset mic to speak and listen to each other.
  • conferenceCallLinkConference Call – Each user can dial into the free conference call phone number; regular long-distance charges may apply.
  • The VoIP and Conference Call systems are not linked. You may use one, or the other, or both, but people only on one will not be able to talk nor hear people only on the other. We have plans for future integration— if it would be useful to you, vote for it.
  • chatPodChat – Chat with everyone in your meeting, or initiate private chats with individual attendees.

Pros and Cons of Each Method

Webcam

  • Pros: Easier and faster if users have their webcam options set. Ideal if a small number of people are giving a presentation to a large number of people.
  • Cons: Only 4 users can broadcast simultaneously, so if more people want to webcam, they have to wait their turn. Mac OSX can sometimes be finicky about webcam setup.
  • Don’t use the webcam if some of your users have slow internet.

Built-in VoIP

  • Pros: Easier and faster if users have their headset mic and sound options set. Good for users outside of the U.S. who cannot call into the conference call. Ideal if a small number of people are giving a presentation to a large number of people (the audience chat their questions and comments, while presenters use VoIP).
  • Cons: If one of the users only has speakers, or a loud headset, or a faulty sound configuration, it may cause an echo. Only 4 users can talk simultaneously, so if more people want to talk, they have to wait their turn.
  • Don’t use VoIP if:
    • Some of your users have slow internet.
    • You need more than 4 people to talk simultaneously during a meeting.
    • Any of the users who want to talk do not have a headset mic.
Learn more about VoIP and how to set it up.

Conference Calling

  • Pros: Supports 100 callers simultaneously, or some can be muted. You don’t have to worry about headsets and sound configurations for all users.
  • Cons: Users need to have access to a phone be able to call long distance. Long distance charges may apply.

Chat

  • Pros: Easy, requires no setup. Has the ability to address all users at once, or individual users privately.
  • Cons: Not as immediate as VoIP or the Conference Call, especially with users who cannot type fast.
  • Using Skype

    Skype is a free online Voice over IP (VoIP) system which you can use to call anyone in the world. The only downside is that each person needs to install the Skype software. Vyew does not directly integrate with Skype, but you can use Skype in conjunction with Vyew by initiating a Skype and Vyew meeting at the same time.
