Scott, thanks for the quick and detailed response. The install on the 8GB Pi 4B failed with various pre-configured .img files. But I was successful using the excellent (!) script you rescued from DSLReports. My only problem (so far) is that the instructions don't match the UI for FreePBX. My application is a bit unusual. I'm not connecting to the public phone network. I'm setting up VoIP over the AREDN mesh network for amateur (ham) radio operators. https://www.arednmesh.org/ It's a worldwide network...
Thanks for posting this, Scott. Perfect timing. I'm attempting to install Asterisk and FreePBX on an 8GB Pi 4B. I'm using Asterisk 21. But I've run into a few problems with the FreePBX settings. I can't find the following and others: SIP Channel Driver TLS Port to Listen On Bind Port TLS Bind Port Any ideas on where to find these settings or their newer equivalent?
