I am trying to set up the above hardware to take advantage of the wireless network in my warehouse. What I am looking for is Incoming PSTN calls go to the WIP310 and when I want to make a call from the WIP310, it goes to the PSTN port of the SPA3102. So far, no luck at all. If anyone can help a noob, I can provide whatever screen shots or addressing info that might help plus my undying gratitude. I'm lost.
