Asterisk 1.8.12 is not getting responses to the INVITES it sends.
Comparing the INVITES, the only significant difference I see is that
Asterisk 1.6.24 includes the "rport" field in the Via header and
Asterisk 1.8.12 does not:

  1.6.24 - Via: SIP/2.0/UDP 222.222.22.22:5060;branch=z9hG4bK58aef527;rport
  1.8.12 - Via: SIP/2.0/UDP 222.222.22.22:5060;branch=z9hG4bK0c8907be

Try setting "nat=force_rport" in sip.conf.  Please reply back to the
list with the results.

There may be other differences between the versions that you haven't
accounted for.  Read the CHANGES and UPGRADE.txt files in the root of
the Asterisk source tree for details.
