Hi Ben,

Thanks for all this.

I came to the same conclusion but for a buck 28 ($1.28) I bought a LCA110
anyway.  And now that I think about it, I do want to play a message from
the Raspberry out to the phone line and then be able to record an incoming
message from the phone line, so I may need the LCA110 to go from waiting
for the caller id to sending/getting messages.

I know.  Sorry about that.  I started here because I know that Tim plays
with the Raspberry a lot and I hoped he would have some ideas and give me a
place to start.  Thanks Tim.
