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.
