Hi,
I have system Centos 5.2 64 bit.
I have installed latest version of a2billing 1.4.2.1 and also tried to install callback, I have followed the depencies and proper steps of installation several times, but not able to start a2billing callback daemon,
I think some issue with installation or may be with source.
I am getting below error, as per the forum i have also searched sessionmaker and checked that sqlalchemy is properly installed. I am also able to get that installed on location /usr/lib/python2.4/site-packages/.
