Subject: freetdm: ftmod_libpri - Do not unlock the channel until all states pending
X-Git-Tag: v1.2-rc1~247^2~33
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a697462a589cab5f70e5608e33837bd6e4ada14c;p=thirdparty%2Ffreeswitch.git

freetdm: ftmod_libpri - Do not unlock the channel until all states pending
                        have been cleared. This should fix issues with
                        state transitions being ignored.
