Hi,

I analyzed the log and I noticed two things:

- you set an upload bandwidth limit to 128kb/s (kilo bits per seconds),
which corresponds to the 15KB (kilo bytes) you are observing

Silly me, why didn't I think of that?! :)

Seriously though, wouldn't it be better to have the bandwidth control limits specified in kilo bytes instead of the current kilo bits? This would avoid confusing naive users such as myself. Much of what happens on a computer or on the internet is in kilobytes nowadays (downloads in a web browser, file sizes in a file manager, etc.), so I would guess that your average John Doe would be happier with defining settings in kilobytes. I for one have never quite made a difference between bits and bytes, well, up until now. :)

General note about the H263-1998 codec use in Linphone: 
The image is fine for about 10 seconds and then it gets pixelated. The pixelation then goes away in a couple of seconds. This happens regardless of the codec max rates. The defaults are anyway unlimited (0).
The pixelation is not caused by packet losses. If the other client for example is ddPhoneVideo, the image received by Linphone is not pixelated. The 10 seconds make me think about ref frames, but I did not look at the code, it is more convenient to act as a simple user :-)))
