[android-developers] Re: When will the Media classes be able to connect to telephone 'conversation' audio channels ?
android-discuss is probably a better forum for this discussion. I would like to correct a misconception: Android is an application processor stack. It does not include a radio stack, nor is it likely to include one in the near future. The radio firmware is typically proprietary to the chip vendor and closely tied to the hardware architecture of the chip.

[android-developers] Re: When will the Media classes be able to connect to telephone 'conversation' audio channels ?
I'd never claim that all of the software on android can be replaced by third party developers. Most system application components can be re-used and replaced by third party apps, but that is a very different statement. Also, just being able to replace the phone app (which is not really any app, but more a core system process) means nothing about being able to do IVR-like features -- all the phone app does is talk with the radio module (running on a different processor) using very high-level commands. If you want to add new features to the platform, you can get the source code and look/work on it, and talk about that work on android-platform. Though again, I doubt you would get very far adding IVR features even directly modifying the platform code.
