I have just finished getting oSip 3.5, eXosip 3.5 and Linphone 3.5
running on a BF537 with uClinux 2010 RC5 and did not see the problem you
speak of.

However, if it helps, i am not using the soundcard or video of the
hardware, in fact i am using a custom plugin to deal with the audio in
and out and putting it back on the network, thus skipping any ALSA/OSS
processing - so maybe the issue you see is related to using the hardware
directly for audio/video processing?

Hope it helps
