Hey,
It's sent when I hit the red button on the phone ( hang up ). It's not
automated.

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
[8s]

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...
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.
