Issue Video playback is intermittent or of poor quality during a sharing session in Microsoft Lync 2010.
Resolution Issues can occur if you are using a desk phone that is not optimized for the version of client communications software that you are using. For example, the video quality might be poor if you are using a phone optimized for Microsoft Office Communicator 2007, but Lync 2010 is installed on your computer. Another example is if you have Office Communicator 2007 installed on your computer and are using a phone optimized for Lync.
To avoid this issue, use a desk phone that is optimized for the version of client communications software installed on your computer. If you must use a phone that is not optimized for your client, try to avoid sharing video. If you cannot avoid sharing video, upgrade your computer to Lync and upgrade your phone to a device that is optimized for Lync.

Poor network connectivity can also affect video quality. We recommend you do not show video over a wireless internet connection, a virtual private network (VPN), or a remote access service (RAS) connection. You should also do the following:
- If bandwidth is a problem, limit other computer activities
while showing a video.
- Stop any unnecessary audio or video.
- Check whether other computers on the network are using a lot of
resources or performing heavy downloads or uploads, and see if
these activities can be delayed or halted.
