Ringing is passed to the bluetooth headset after 2 seconds

I have a nokia lumia 620 and I bought a nokia bh-110 bluetooth headset.
The problem is that after my phone is ringing for two seconds the ringing is passed into the headset.
How can I alter this behavior?
Thank you.

I'm not sure I understand your question. Do you not want to hear notifications of calls in your Bluetooth headset?

No I want to hear only the phone ringing, because I miss some calls now that it rings only for two seconds.
