Summary:                    [patch] Missing fallback to audio fax feature when
T.38 re-INVITE failed for 1.4
Description: 
When a  T.38 re-INVITE failed with an 488 or 606 answer, we should fallback
to audio fax by send a re-re-INVITE without T.38. The function is
backported from 1.6 asterisk. Some people say this is a feature, other say
that it is a bug that 1.4 does not fallback to audio. Here is the patch.
