I think this is a very common situation, so I'm not really sure what
your problem is. Perhaps it's because I don't use an internal card,
but in my situation it works just fine. I dial a number on my SIP
phone, Asterisk goes through the dialplan, and puts the call out via
the SPA3102. In my ear I hear ringing sounds, busy, wrong number or
someone talking to me just like if I had connected a "normal" phone to
the PSTN line.

I haven't done this yet, and was looking for information.

I was under the (apparently false) impression that Asterisk/Dahdi
didn't connect the two legs until the callee had gone off-hook.

This is true, but you already answered your own question in your original post: since Asterisk cannot know whether the called party (dialing out via an FXO port) has answered or not, it assumes the outgoing call is 'answered' as soon as dialing has been completed. Because of this, the calling channel is bridged to the called channel as soon as dialing has been completed, and the calling party will hear the progress of the outbound call.
