Hey,
It's sent when I hit the red button on the phone ( hang up ). It's not
automated.
So I think there is no solution within Kamailio to work around the bug
in the phone. You would need to modify tm module to send delayed CANCEL
not after 100 trying, but only after 101-199 response.

True. David, is the 47 sent by the phone autonomously or due to some
user interaction (e.g. rejecting the call)

Cool, nice feature.
Unfortunately it doesn't help with David's problem, as the phone
obviously does not see the additional CANCEL - probably the phone's
transaction layer responds again with 481.
What's strange is that according to the dump it does finally reply with
a 487, but 8s after it sent a 481 to the last CANCEL:
<- 100
CANCEL ->
<- 481
<- 180
CANCEL
<-481
[8s]
<-487
