A VoIP Call Back System

**I need a VoIP call back system similar to Google Map local search**... Go to <[login to view URL]> and search "web design 91731", and click on any "Call" link beside a phone number. The page would ask you to **Enter your phone number**. After you do so and click on Connect for free, the system would call you first and then call that business number after you pick up phone. It is a two-way phone call. The syste first connects to a caller or site visitor, and after the phone is picked up, it then connects to the business phone numer listed so that the visitor can speak to the company directly via phone. This function is similar to a toll free phone call, but without need of a toll free phone number. The system should tell the caller which nation's phones are accepted for using it. And also it should be able to restrict the office hours when a call woud be allowed automatically. To take this project, **you must have previous experience in VoIP and understand of and can handle Asterisk, Trixbox, and VoIP termination, etc., related issues.** ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
