We are starting a Source Forge Project here. To record your call logs to sqlite using a popular .net agi library and a popular .net sqlite library.
This project was inspired by the WDTVLive mods made by B-Rad here and the asterisk app for it found here
To date there has been no code posted, but there is a good base already written. The idea is to allow notification of calls as they come in to start and log all data to sqlite as well as have an app to view the data. Currently this is only a gridview but will most likely be changed to a ListView.
