I've uploaded a patch called 12215_temporary.patch. This patch takes the
basic idea behind asterisk-1.4.19-chan_sip-loop-detection-fix-v2.patch but
also adds some amended logic later in handle_request_invite to make sure
that we actually process the reinvite correctly if the channel is still in
the AST_STATE_RINGING state.

This, specifically, should make remiq's failed test work properly. The
reason I've placed the word "temporary" in the patch's name is that there
may need to be other cases in the switch statement that are handled
differently depending on the invitestate. This specific patch will handle
the case of receiving a re-INVITE on an outbound call before the channel's
state has been changed to UP.

Please test this if possible and let me know if this is a move in the
right direction. Thanks!
