As far as I know, there is no need to modify your phone's firmware or framework. It is sufficient to build your application as part of adnroid's build. neeloor2004, if you enlist into android's open source projects using repo (Mark provided you the link), add your project sources to the build, then from your sources you should be able to access telephony internals public classes. Be aware though, that whenever Google changes/refactors these internal classes, your app would have to be recompiled again. In my personal opinion, that could cause huge maintenance problems, which is why Google advises avoid taking dependencies on internals.
