Strangely enough I have used this many times with our POTS from AT&T. We get ring splash, but didnt get a ghost ring into the system, just the valid ring that was redirected to the VoIP lines after forwarding. Although I think i had the Asterisk-GUI creating the dialplan on these systems, not sure if it changes anything besides the dialplan though that would cause it to seem "normal" during a forward of a POTS line.
