Well, I've been working way to much the last month to get too far...
I bought a PAP2 on eBay, unlocked it and got it working. I have my internal extensions working. The trunk to the PSTN is a different story. The knock-off x100p card shows up as a "Tiger Jet Network Inc. Tiger3XX Modem/ISDN interface", so I am working through that problem.
I had my UTS F1000 wifi phone working with *, but somehow a vonage firmware upgrade came through and trashed the phone (I had unlocked it), so that distracted my attention. I've had to send it off to Germany for a fix because I'm no longer an vonage customer and they won't fix it, even though it is still under warranty and they screwed it up.
I hope to have it all up and running by the end of this month.
