Here is an idea.  There is a Yahoo group called the "RAT Ring".  "RAT"
stands for Remote Access Terminal.  Although it is PIC-based, what
they are doing is essentially having the PIC actually perform the
modem functions and other activities with as little reliance on
external hardware as possible.  There is no reason why the same ideas
could not be applied to the AVR.  Also, there is no reason I can think
of that would keep you from using more than one AVR in the project,
i.e., one acts like the modem, the other does the dialling, etc.

Basically, what I am getting at is see how much you can do in software.
Hope this helps.
