I was Using freepbx-2.1.1, Asterisk 1.2.29 and Asterisk Addons 1.2.9
i tried to upgrade to Asterisk 184.108.40.206 and Addons 1.4.7
all of the IAX trunks got not working at all.
I tried to downgrade by “make clean; make; make install” in Atserisk 1.2.29 directory.but “make” gives errors in the end.
How can i downgrade asterisk again and undo all changes i made.
and can Backup and Restore return all the previous asterisk configurations?
