You experience the following issues when you use a Microsoft LifeCam together with Windows Live Messenger to make a video call to a contact:
Close LifeCam or any other webcam softwareFirst verify that another program (such as the LifeCam software) is not running and using your LifeCam. Close any other programs that may be accessing your LifeCam. If you do this and it does not resolve the problem, follow these steps in the order in which they are presented.
Verify the status of the Windows Live serviceYour video call could fail if the Windows Live Messenger service is experiencing difficulties. Check the network status of the Windows Live Messenger service. To do this, visit the following Microsoft Web site:
Install the latest version of Windows Live Messenger
Configure audio and video settings in Live MessengerConfigure audio options and video options in Windows Live Messenger by using the Audio and Video Setup wizard. To do this, follow these steps.
Note Make sure that you exit the LifeCam software before you start Windows Live Messenger.
Verify that the audio settings for Windows are correct
Check your firewall and proxy settingsDetermine whether your firewall or proxy server is blocking ports that are needed to make the call.
Note If both you and your contact are using UPnP-certified NAT routers and firewalls, closed ports in the proxy server or in the firewall should not be a problem. If one or both of you have a non-UPnP NAT router or firewall, you have to configure that device to open the ports that Messenger uses.
Warning This workaround may make your computer or your network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this workaround but are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk. To resolve this issue, configure the firewall to allow for incoming traffic on UDP ports 5004 through 65535.
For more information about how to open ports in the firewall or in the router, contact the manufacturer of the firewall or the router. If you are on a corporate network, contact the network administrator.
For information about your hardware manufacturer, visit the following Web site:

Specific issues that you may experience
EchoIf you hear an echo when you make a video call, or if the volume bar does not work when you make a video call, try the audio call. Then, try to share video.
No audioIf your computer does not have the USB capacity to support both audio and video, you may find that audio and video do not work at the same time. The computer prioritizes devices when there is insufficient capacity. Typically, keyboard and mouse take priority. Therefore, avoid plugging in your LifeCam to a USB hub. Connect your LifeCam directly to a USB port on the computer. If the problem continues, you may have to unplug other USB devices to provide more capacity for the LifeCam. If there is no audio when you make a video call, make sure that your computer uses USB version 2.0. Contact the computer manufacturer to obtain information about the USB version.
