Hi!
Since I bought the n900 I experience choppy audio with SIP calls over wifi and sometimes over 3G - so I searched and found following bugs which seem to describe my SIP problems very close (https://bugs.maemo.org/show_bug.cgi?id=7302 and https://bugs.maemo.org/show_bug.cgi?id=6936).

Unfortunately even though the mentioned bugs should be fixed with PR1.2 I still have the choppy audio problem with SIP calls. I'm unsure if the bugs are realy fixed or if another component cause the audio problems.

To investigate this I installed syslogd and exported TPSIP_DEBUG=all and TPORT_LOG=1 (see the syslog output here: http://pastebin.com/sAEf0m7D) but I realy have no clue what causes the choppy audio. I noticed a problem with gstreamer (Internal GStreamer error: clock problem.) in the syslog output but don't know if this could cause such symptoms.

Let me say that I use SIP over wifi very often on linux with twinkle and with my old E60 without any problems.

What do you think - might this be a new bug or is the old bug simply not fixed or is it a misconfiguration on my side?
