I know there is the open source asterisk pabx and scripts which offer the option to utilize call center functionality. I am looking for a callcenter solution which I can offer as hosted service to clients. This solution should consist of managable features like: -Predictive dialer -CTI -IVR -call scripts -voice recording -remote login from home over IP for example -reporting IMPORTANT: **Let me have any feedback if you have this software ready made and or can provide me a live demo. ** ## 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.
