It is strange that with the slingbox streaming only between 450-480 kbps I can have a good quality Skype call in India.
But before, during and after the skype call the bitrate range doesnt seem to get affected at all. What could be limiting the bitrate to stay only in this range ?
I have taken pictures to illustrate this.
We need to get more information about the 2 networks, at the Slingbox location and remotely. I'm a little bit confused, which is the upload speed in India using speedtest.net? Also it's very important to confirm that you are not using the Slingbox behind a company firewall because it could have bandwidth restrictions.
In the meantime, please take a look at this article,
