Assuming you've got ROM to hold the code/constants and that RAM is only
used for variables, then 68 kB should probably be enough.

The 8 kbps mode only requires around 4 kB of RAM (excluding code and
constants). The jitter buffer probably requires a bit less than that. As
for the echo canceller, it's probably more, but it depends on the
settings you use.
