How about this as a documentation issue (or lack of). Amont others, the terms answer and hangup seem to be used for a number of possible responses to calls, which confuses me greatly. Where is the designed behavior written up. Almost all of what I can find is just hope to set up Asterisk and is limited in scope.
Also, “Asterisk works just fine” is not a definition of anything.
The help I am seeking is to understand what Asterisk is doing when I have configure the trunk (in this case using FreePBX) and a call comes in with an unconfigured DID. If it is not doing what I need (don’t answer the call and respond with a SIP 404) how do I “configure” it to do that?
So far, what I am getting is not anything I can translate into a solution or is a suggestion of where I can go to find the detailed solution.
I am grateful for peoples help but, so far, the community support forum is not working.
