How to get voice input from Headset

Hi All,

Currently I can successfully play a sound file to my headset (Jabra 250v) by setting .asounrc and use "aplay -D bluetooth test.wav". But I can't get voice from the headset by using "arecord -D bluetooth record.wav"

The HCI conversation seems ok but no SCO packets occur.

My configuration:

Linux 2.6.24-21-generic (Ubuntu 8.04)
bluez 3.26
sco.ko with force_scofix=1 parameter

hcidump result as attachment.

If you can give some hint I'll appreciate.

Thanks for your time.
