call center feature on website

Hi there! I am looking for a web based call center solution that can support voice for my website. It's one of the portions of my website project . In such a solution a user coming to my website and requires assistance/help can click a link to connect to an operator and have live voice conversation . The solution should be able to handle multiple operators and users . The call center must support the usual call center features such as : 1) Greeting message 2) Music on hold when lines are busy 3) Ability to create departments such as sales, marketing, customer support, etc and assign each department operators. 3) Anwsering machine when no operator is available. All source codes and documentation must be provided and the solution should work since i have to give demo but since it is not a commercial nature project , it should work as a prototype , but doesnt have to go through all the quality issues. I prefer looking for some expert with already written code or a quick solution. I am really in need of help here and I hope you can help thanx Ryan ## 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.
