I would like to speak to some knowledgeable programmers to and assign some tasks to know who can help us with these servers and programs long term.

Hello. Today I'm looking for a professional Asterisk/FreePBX programmer, that knows about DialPlan writing and maybe other interfaces of Asterisk. I need a simple application that allows users to log-in the voice menu, and be able to record a message, or to scroll (using the touch-tone phones) through messages others were left for the community. It's like a primitive BBS or Internet forum, but for use by people over the phone. It seems to me it can be achieved by dialplan programming. but if an external application server is better - I think it will be good for me also.
