Hi
You can upgrade the 1.3.4 database using the scripts provided in the A2Billing tarball. Back up first so you can go back.
The web directories simply replace the contents of the existing directories.
the new a2billing.conf replaces the old one, but the location has moved to /etc/a2billing.conf not /etc/asterisk/a2billing.conf and the agi-confs are now database driven.
You replace the cronjobs with the new ones.
Replace a2billing.php with the new version.
We have a svn directory, 1-current, which is where we do all our commercial installs from, the beauty of using SVN and symlinking from this directory to all the other elements (Webs, Crons, a2billing.php) is that when you come to upgrade, just do an svn update, and run the latest mysql upgrade scripts, and you are upgraded.
We keep the svn directory 1-current right up to date, and always is the latest stable version in there.
You can of course purchase the scripts off the internet. The A2Billing project does not get any revenue from the sale of these scripts as far as I know, e.g. I do not know if the author makes anonymous donations to us, based on his revenue he makes by selling these scripts. However we have made some money providing consultancy to clean up after scripts that have been downloaded from the internet and blindly run without being aware of the results. Star2Billing S.L. do not provide install scripts
The install is not that difficult, and well documented - one forum member said that the installation was so easy and well documented that
...even his mother could do it!
In respect of upgrading to 5.2, I cannot see any reason not to, it is stable code, and been out since
02-Nov-2006 it's just that Redhat are a tad slow in catching up.
I use the
utter-ramblings repository from Jason Litka
Any problems, come back to me either on this thread or in the forums, and we will do what we can to assist.
