Re: [android-developers] Re: what needs to be change to enable call recording on android platform?

(However, do I agree with you that it would be nice to see the
telephony firmware that's present in the modem? Sure, I do! Does
this have anything to do with Android proper? Not really. I agree
that if you want a completely open telephony platform it would be
great to have open telephony firmware. If you are interested in this,
perhaps this would be a good link:

http://en.wikipedia.org/wiki/List_of_open-source_mobile_phones

Still, not something to trash Android for, it's really feasible to say
that we can run open telephony firmware at this time. Or maybe it is
and I'm just being naïve about the politics of handset manufacturing
and distribution.)
