Apparently, the Cisco is getting something back from Asterisk which it
thinks is a bad message and as a result of that it sends a CANCEL
request back to Asterisk.

Although I am not sure what that bad message might be, judging by the
fact that the last message Asterisk sent out to the Cisco shortly
before was the RINGING message, I take a guess that there might be
something funny with that. Following that thought, I would try the
dial command without the "r" and also without "t" and without "tr" and
see if that makes any difference.
