I have 2 locations with internet connection (512 kbps downstream and 192 kbps downstream) with static IP on both. I'd like to interconnect their PBX (I mean, make phone calls between them, I don't need anything else). I heard I can do that with a PAP2 in each location, but I wrote an e-mail to Linksys to ask and they answered that the PAP2 cannot be connected to PBX, only to regular phones. Is that true? Is there any other way to do this?
