Solved the "Don't Answer, Send SIP 404 to Calling SIP Trunk" Problem

Two lines of code in extensions_custom.conf. Basiclly [ext-did-custom] and, essentially, “Hangup(1)”.

Too bad no one was able to actually come up with a clear actionable solution and it took me a couple of week of fooling around to get it in the right place ( context label ). I learned a lot more than I wanted to know in the process.

My suggestion is, read the questions more closely. In a lot of answers on this forum, though well meaning, are a miss on the question actually being asked. Typed communication is difficult and I have no illusions that I am always clear as well.

As I always say “Don’t listen to what I say, listen to what I mean”. LOL
