Currently in my FreePBX system status shows IP trunk online, but on my spa 3102 webpage shows PSTN Line Status as Registration State: Failed. Outbound and inbound calls fail. I followed the how to at http://www.freepbx.org/support/documentation/howtos/howto-linksys-sipura-spa-3000-freepbx for all my configuration settings. My line 1 /fxs is working just though. Does anyone have a suggestion of what I can try to resolve this?
