Write some software

I have a good set of bash scripting as well as python skills. I have been a Linux nerd for quite some time now and know the in and out debian based systems, I can understand the requirements and work alongside to provide the best solution required. I need the exact specification of the requirements to provide you with a timeframe .

I am not sure if I understand your description correctly . Please corrcet if I am wrong here . Is it just installing and configuring FreeSWITCH on CentoS 6 server or will the project includes writing custom modules to freeswitch ? Appreciate your help !
