I'm able to register a 7940 against Asterisk 1.8.4.1. You might try
out that version as it has the fix for registering Cisco phones.
However I thought the bug was introduced in 1.8.4 and not 1.8.3.3.

I know in the past when I had issues registering Cisco phones I had to
make sure the nat settings matched. If you set nat=yes in the sip.conf
you must set nat_enable: 1 in SIPDefault.cnf for the phone. What I
noticed was when nat=yes is set in Asterisk it ignores the rport and
always sends the reply on the port used for the request. Cisco will
ignore this reply and not register.
