No ring when connecting 6230i to BT headset

Hi,

I have a 6230i cellphone, and also a BT headset (Scala-500), which is working perfectly with the phone. The only problem with it is sometimes(!!), when a call enters, the phone doesn't ring (only the BT headset does) and sometimes(!!) they bouth do.

I do want the phone would also ring because the BT headset is not always on me. How do I define the ring will be heard by bothe the BT headset and phone for all incoming calls?

I am having the same preoblem with my i-mate JASJAM ( ~ HERMES ~ HTC ~ 838) and Jabra BT8010 headset, the ring gets transferred to the headset and the phone doesn't ring.
