I keep wondering whether an FXS with no dial tone would do the job (can that be changed in indications.conf?). We used to test DID trunks inbound with a butt set. We'd get battery (48V) but no dial tone. We'd just send DTMF and it'd work. I remember that one of the quirks of analogue DIDs was that the 48V came from the CPE side instead of the CO, so an FXS might be hackable.
