Hi, I am new user in VOIP, I installed SER with asterisk on two different servers. I installed ser-0.8.12-0.i386.rpm and ser-mysql-0.8.12-0.i386.rpm according to instruction on fedora core 4. I configured the UA's and those are making calls between each other but they are not authenticated by database(mysql). I want to confirm that is there need to seperately install more packages like (authntication,acc,radius) with ser-0.8.12-0.i386.rpm on the ser machine or all the packages are included in the ser-0.8.12-0.i386.rpm file during installation and i just have to configure the ser.cfg. what is the best method to access the database(mysql) with user agents.
