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.

So it looks like there's really no issue in connecting a remote SIP
client with a PSTN number through an FXO port + ADSL VoIP modem to
take advantage of free phone calls.

Thanks everyone.
