I've checked RFC 3265 but could not find a

should ask at the sip-implementors list.
i looked at rfc 3265 and found this in section 3.3.6:
Note that the NOTIFY messages triggered by SUBSCRIBE messages with
"Expires" headers of 0 will contain a "Subscription-State" value
of
"terminated", and a "reason" parameter of "timeout".
wireshark dump reveals that notify request is not generated at all when
ua un-subscribes a bending subscription. there is just 202 followed by
nothing.
