What I see from you trace, (better if next time you put a ngrep-sip trace ..), 
is:

Apple                         DLink                          GW
INVITE      ->
                 <-         100 Trying
CANCEL    ->
                 <-         200 Canceling
                 <-         486 Request Canceled
ACK           ->
-------------
New INVITE ->
                    <-      100 Trying
[the next is supposed, not in trace]
                              INVITE              ->
                                                      <-      100 Trying
[... end supposing]
                                                       <-     INVITE
                    <-      INVITE
180 Ringing ->


Maybe you are rerouting the second invite back to your UAC, or you do some 
aliasing ... or something similar.
