 This part was initially extremely daunting. Not helping matters is that the fact that there are no pages online (that I could find) that discuss a viable minimal configuration for a recent Asterisk version. Apparently either nobody is starting fresh with Asterisk in 2022 or nobody is interested in writing about it. Further frustrating matters is that Asterisk's official wiki, a Confluence site, went down shortly after I began the process of setting Asterisk up. This part was initially extremely daunting.

-I started here, and essentially trimmed the config file down to ''autoload=yes'', because I disabled all modules in ''make menuconfig'' that I didn't want to actually use.+I deleted the config files installed by ''make samples'' that were installed for all modules I explicitly removed:

 +===== pjsip.conf =====
 +
 +It was at this point that I gave up because the file is approximately three bibles long and simultaneously contains every example known to humanity and yet no information I'm capable of parsing and retaining. I'll come back to this later.

 +====== Dialplan notes ======
 +
 +===== Trunk configuration =====
 +
 +A&A SIP trunks don't seem to indicate the incoming number, or maybe I configured the trunks on A&A's end wrongly. The solution is simply to specify a contact header, so I have devised the following internal dialplan for inbound trunks
 +
 +8 44 1382 00 339
 +
 +Where 8 is the incoming number prefix, 44 is the country-code, 1382 is the area code of the line, 00 is the provider number, and 339 is the last few digits.
 +
 +Provider numbers are as follows
 +
 +00 - A&A VoIP
 +
 +01 - Voipfone
 +
 +02 - sipgate
 +
 +03 - Twilio
 +
 +99 - SIPBroker
