 Sundog is right.

A longer answer is that whether the application processor can access in-call
audio is
very device specific; on the G1 this is not supported (only the modem
processor can).

For the record, there are two CPUs on the G1, an ARM9 handling
GSM/radio/whatever, and the
ARM11 Android runs on (there are also two DSPs, the mDSP for the modem, and
aDSP for
applications; isn't that fun :-))
