how to improve the video quality send by lync 2013?
we have one sip client  make call with lync 2013 client, and each other support MS rtv video capabilities, after the sip session begin, then video rtp packet send on each directory, all the time our client send 720p video codec to lync 2013 client , but we only receive the lower format video codec from lync 2013 , and the video format is changed all the time ,some times is 720p then 960*544, then 960*720, or 630*360,,etc. we wonder how can lync client send stable 720p video codec, and we have acheive the funtion accord ms-rtp.pdf document, and our client can calculate bandwidth using rtcp step accord ms-rtcp , then we should do what else in order to get stable 720p from lync 2013...thank you.

To improve video quality, you will need to increase network bandwidth.

thank you

now we realy have enoght network bandwidth, is heigher to 4-6Mbps, so I think which is in one right work enviroment.

Now I notice that the video format received from lync 2013 at the begining of the call is 720p,  and some times change to 960*720, or 960*544, but for many time it may be change between these three  formats, but in some times the video format would change to 640*360, once which change to this mode then it would keep in this sitiunation for long long  time, and would never chanege to the heigher ones so it is one incredible things.

how could we change this sitiuation to get one good video format for heigher video effect.
