AVAYA IP Office Caller ID integration with SQL/ASP.Net application

We have Avaya IP Office, and need it to talk to our in-house home-grown .net web application. Based upon the caller ID of the caller (CID), I'd like our call center application, which is browser based, to automatically search for the calling customer and pop up the customer's info on the browser-based application. Also, I'd like some custom speaking scripts to be displayed to the call center agent based on the called number (DNIS). Required skills: HTML, .NET for Web, SQL Server, Avaya IP Office, TAPI
