I dont know why I didnt think of this before...
Surely a connected and working pap2t ($98 at DSE), could just have its PHONE1 port connected directly to an FXO port on an Asterisk box? Then the pap2t would give dialtone, the asterisk box would think it was just another POTS line, and pretty much everything would be plain sailing?
Wouldnt get any multiple connections on the line (but that doesnt bother me).
Is this so obvious that everyones doing it and im a noob for not thinking of it earlier, or is there some issues with doing this.
My first FXO card arrives next week, so i cant test this yet.
