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

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

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. Obiously the device is buggy.
But there is also on strange thing at Kamailio: it retransmits the
CANCEL although it has already received 481 response on the CANCEL
request.
The first 481 stops the CANCEL retransmissions, however each additional
provisional reply received after that will trigger a one-time CANCEL
retransmission. That's why you see another retransmission after the 481,
it's the "response" to the 180...
