Project Description:
Remotely install, build, and secure A2Billing, Freepbx, and Asterisk (Is it better to build from Source or go with a Distro??)
Would like this to be installed on Centos 6.x
Apply best practice security methods using a combination of IPTables and Fail2ban to secure the environment (If you have a better solution I'm open to that as well)
Configure/Modify the system for strictly pinless calling card system where customer is authenticated by his/her registered phone #
Configure/Modify system for traditional calling card setup that will require a pin (This will be used to sell calling cards on line sometime in the future)
Build the Services, Rate Tables and Billing
And if you can find, install Unlimited G729 channels license that would be great to (This could be a separate line item which we could discuss payment for)
Please if you are not familiar with A2Billing and have never done a Pinless Calling Card System implementation please due not respond.

Skills required:
Asterisk PBX, MySQL, VoIP, Web Security
