Hi List, 
  I created a patch that makes user can control their call volume via a
slidebar when calling.
It's uses AT+CLVL controling the call volume.  According to 
the valid range is 0~5, and the volume degree maping to TI Calypso volume range
0~255 equally. 

By current the volume default is 3 of 0~5, and TI calypso default is 177 of
0~255. It will be switched and  follow the setting in QPhoneProfile. ie
AT+CLVL=153. I tested and found it's okay for me. The volume is loud
enough for me, and people on the other side of call does not complains at all. :-) 
Maybe other device need to switch to a larger value.

Users can control the default volume by using QPhoneProfile, and
PhoneSettings. Or edit /opt/Qtopia/etc/default/Trolltech/PhoneProfile.conf directly.

If there are no other issues, I will commit it tomorrow.
