Settings:
 - Auto record mode = All 
 - Sampling Bitrate = Medium
 - Beep Suppress = Enabled
 - Record Format = AMR
Phone:
 - Hardware: Nokia E7-00
 - Software: 022.014 (Nokia Anna)
Symptoms:
 - When using phone only beep suppress works ok
 - When using a bluetooth headset beep suppress works ok
 - When using factory installed bluetooth car kit with HFP, a beep will be heard on both sides in about every 10 sec.
Is there something that could be done to suppress the beeps also when using the car kit?
