C/C++ Expert for Dialogic conference application

I have a functional C++ telephony application that uses the Dialogic Global Call and conferencing APIs ? to receive calls and establish conferences etc.. We have also web interface(in PHP) ? which creates/maintains/updates conference details on web. Currently it got pretty bad design where this telephony application is polling MySQL DB ? for information exchange with web server (PHP interface). This is causing lot of problems including high CPU usage & scale issues.? we need to redesign this application up to some extent where we can remove database polling model and ? use TCP/IP based ( using sockets) design for web server ? to? ? communicate with telephony application. Here are skills required to qualify for this project :? I'm looking someone expert C/C++, socket programming, PHP Web knowledge is preferred , Dialogic API skils preferred. ? If you have some special ideas on web side like Ajax/Comet support to convert current PHP application that ? would be extra bonus !! Please bid only if you are indiviudual programmer and have have developed this type of application in past. ? I may increase amount in future and pay bonus based on your skill and experience. I'm also primarily developer and I'll be involved through out the project and will help in all possible ways. Thanks
