Asterisk Reports (html) in asp.net webform

Right now i have interface with asterisk to do Click2call feature. But, i would like to improve this interface and functionality on my asp.net web application. What im requiring is creation of 3 webservices that will run on asterisk services and will be consumed in asp.net application. 1- Webservices to return all current calls in progress. fields: Agent Name, Agent Extension, Phone Number, route (incoming or outgoing call), start time, duration, waiting time. return: a Json object with this list of elements. show: show a nice html table in asp.net 2- Webservices to hear specific current call. User will see previous table and click over a call to send asterisk command to let him hear that conversation in especific extension. I mean, if agent A is having a conversacion with a customer in phone number 787-000-0000 and monitor click over that call then webservices will recieved like param the extension of people that will hear that conversacion in their softphone. 3- Webservices to return calls History for specific date. fields: Agent Name, Agent Extension, Phone Number, route (incoming or outgoing call), start time, end time, duration,waiting time. return: a Json object with this list of elements. show: show a nice html table in asp.net Delivery asterisk part: you must test it on your side and give me script to be implemented in my side and how to do it. asp.net part: webform application written in vb.net
