I suspect this is happening because you are using
[last_CSeq:]
when sending the "200 OK" for INVITE. But the last_CSeq receveid was for
CANCEL.
You should take a look at the messages being exchanged.

If i remember the RFC, the Via header in the CANCEL must be the same as in
the INVITE.
Try this in the CANCEL:
Via: SIP/2.0/[transport] [local_ip]:[local_port];branch=[branch-3]
