Dialing an invalid extension causes incomplete hangup sequence.
Revision -r1489 corrected a deviation from Q.931 Section 5.3.2. However, this resulted in an unexpected behaviour change to the upper layer (Asterisk). This change restores the legacy hangup behaviour if the new API call is not used. Use pri_hangup_fix_enable() to follow Q.931 Section 5.3.2 call hangup better. (closes issue #17104) Reported by: shawkris Tested by: rmudgett git-svn-id: https://origsvn.digium.com/svn/libpri/branches/1.4@1688 2fbb986a-6c06-0410-b554-c9c1f0a7f128
