Just to verify, can you send the debug isdn q931 trace ?
However when the person on the IP phone hears a disconnect tone, he/she should hang up and that's it.

Hi,
ISDN doesn't need tones for disconnect. A Q.931 message specifies when the remote has disconnected. Consequently no supervisory disconnect configuration is necessary.
Note: In some countries, for an incoming call, it is not possible to actually terminate the call until the caller has disconnected.

I meant that we i receive a call from the (PSTN using the BRI) and someone answer the phone and when the calling (the one who call from the PSTN) hang up i still listen in my IP Phone to the disconnect tone then the Busy after that it disconnect bu it takes so much time (about 30 secs)

With ISDN, you don't.
Thanks for the appreciation and good luck!
