Upgrading from version 1.0.xdownload the asterisk-1.2.0.tar.gz and if needed all other necessary downloads from http://www.asterisk.org/download. after unzip there are two ways for installation:
1) run make, make install and make samples. it is like a complete new installation. your old config files will be renamed to .old if you run make samples
2) run make, make upgrade.
It is recommended in both ways that you remove the *.so files in your asterisk modules directory prior to doing "make install" from the new 1.2. if you don't remove you got error messages by starting asterisk. then you must remove following .so files in your asterisk modules directory (should be in /usr/lib/asterisk/modules/):
If you are updating from a previous version of Asterisk, make sure you read the UPGRADE.txt file in the source directory. There are some files and configuration options that you will have to change, even though we made every effort possible to maintain backwards compatibility.
