I have changed VoiP vendors and the new company uses a Linksys SPA-2102 adaper. My previous company used a PAP-2 but it was locked so I am trying to install the SPA-2102. The insrtuctions for forwarding port on my Telmex Infinitum_EchoLife-HG520b router don't seem to work. I enter my static ip address and it does not go to the router/modem, it just times out. So the router is not seeing the telephone digital adapter. Any suggestions?
