I’ve been trying to get this Cisco SPA-3102 set up as a PSTN trunk for what feels like forever, and I must have read and tried everything posted on these forums and on the wiki, but to no avail. I have the SPA setup as an extension (100) on Raspbx no problem, and Line 1 shows as registered on the SPA info page.
My problem is that no matter what configuration I try, I can’t get any inbound or outbound calls through the SPA-3102. The info page shows that the PSTN line is on hook, and when I call my phone number it will show the ringing status correctly, but it’s registration status always Unregistered.
I’ve attached some images of my configuration and I’m hoping that someone can spot something really obvious that i’ve missed because honestly, I feel like i’ve been banging my head against the wall for a long time now.
