Alpine Linux latest-stable (written when latest-stable == 3.16.0)

====== Note about missing packages ======

Some Asterisk modules are unavailable due to the lack of available packages on Alpine Linux. These currently are:

  * ''beanstalk'' - Available as a package, but I'm not installing it :)
  * ''codec2'' - Unavailable as a package, but the [[https://github.com/drowe67/codec2|most recent commit]] does compile and install
  * ''iksemel'' (Jabber-specialised XML parser) - Unavailable as a package, most recent source simply doesn't compile, but [[https://github.com/timothytylee/iksemel-1.4|version 1.4]] does compile and install.
  * ''nbs'' (Network Broadcast Sound) - Unavailable as a package, compiling from source doesn't work without patching for ''musl''.
  * ''osptk'' (Open Settlement Protocol) - Unavailable as a package (unsure why), couldn't be bothered finding source and seeing if it compiles.
  * ''radius'' - Installing ''freeradius-dev'' is not sufficient, and I'm not interested in figuring out what package is required for this one.
  * ''resample'' - Installing ''libresample-dev'' is apparently not sufficient, even though the install-prereqs script checks for the header file installed by that package before attempting to build from source.. I do not care enough.
  * ''vpb'' (Voicetronix) - Unavailable as a package, website is confusing, don't care enough.

===== Applications =====

  * ''app_jack'' is unavailable due to resample
  * ''app_osplookup'' is unavailable due to osptk

===== Call Detail Recording =====

  * ''cdr_beanstalkd'' is unavailable due to beanstalk
  * ''cdr_radius'' is unavailable due to radius

===== Channel Event Logging =====

  * ''cel_beanstalkd'' is unavailable due to beanstalk
  * ''cel_radius'' is unavailable due to radius

===== Channel Drivers =====

  * ''chan_misdn'' (ISDN BRI/PRI) is unavailable due to isdnnet, misdn and suppserv
  * ''chan_nbs'' (network broadcast sound) is unavailable due to nbs
  * ''chan_phone'' (linux telephony api) is unavailable due to ixjuser
  * ''chan_vpb'' (Voicetronix) is unavailable due to vpb

===== Resource Modules =====

  * ''res_corosync'' is unavailable due to corosync
  * ''res_timing_kqueue'' is unavailable due to kqueue

====== Install commands ======

Not exactly a ready-to-run script, more a log of all the commands I ran in the pursuit of sippies. During the menuconfig step, I enabled everything possible except for any deprecated modules that aren't enabled by default anyway.

====== Configuration ======

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.

===== Files removed =====

I deleted the config files installed by ''make samples'' that were installed for all modules I explicitly removed:

  * app_skel.conf
  * cdr_adaptive_odbc.conf
  * cdr_beanstalkd.conf
  * cdr_odbc.conf
  * cdr_pgsql.conf
  * cdr_syslog.conf
  * cel_beanstalkd.conf
  * cel_odbc.conf
  * cel_pgsql.conf
  * func_odbc.conf
  * misdn.conf
  * osp.conf
  * oss.conf
  * res_odbc.conf
  * res_pgsql.conf
  * res_snmp.conf
  * sip.conf
  * sip_notify.conf
  * vpb.conf

===== 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.
