最近Asteriskを触っているのでこれまでの理解をまとめておく。 このページはUbuntu 20.04を想定している。

Asteriskのインストールと起動
rhoboro/asterisk-dockerリポジトリでDockerイメージを作ったのでDockerfileを見れば必要な情報は大体わかるはず。 また、使いたい機能によってはインストール時に選択する必要がある。（あとでできるのかもしれないが、調べていない）
Dockerfileでは下記コマンドでフォアグラウンドで起動しているが、Docker以外の環境ではsystemctlでデーモンとして起動しておくのが良さそう。
# フォアグラウンドでAsteriskを起動
$ asterisk -vvvvvgc
その他自分がよく使うコマンドはこの辺り。
# Asterisk CLIの起動
$ asterisk -vvvvvr
# 再起動
$ asterisk -rx 'core restart now'
# 停止(systemctl)
$ sudo systemctl stop asterisk.service
# 起動(systemctl)
$ sudo systemctl start asterisk.service
# 再起動(systemctl)
$ sudo systemctl restart asterisk.service
# ステータス確認(systemctl)
$ sudo systemctl status asterisk.service
# CLIコマンド一覧を表示
*CLI> core show help
Asteriskの設定は基本的にconfファイルで行い、反映は再起動やリロードコマンドの実行が必要。 ただし、DBからユーザー設定などを読み込んでくれるAsterisk Realtime機能もある。
CLIでのログについて
CLIではリアルタイムで様々なログを表示できる。 つぎのコマンドは一例なので core show help で気になる機能のログを表示できないか確認するのが良い。
# SIPのログを表示
*CLI> sip set logger on
# PJSIPのログを表示
*CLI> pjsip set logger on
# AGIのログを表示
*CLI> agi set debug on
# ログレベルを更新
*CLI> logger set level DEBUG on
Asteriskを用いたPBXサーバーで利用できるもの
Asteriskは発着信時の挙動を次のようなextensions.confに記載して制御する。
[from-internal]
exten = 100,1,Answer()
same = n,Wait(1)
same = n,Playback(hello-world)
same = n,Hangup()
ここで、AnswerやWaitはDialplan Applicationsと呼ばれるもの。 Asteriskはこのように各処理をアプリケーションとして用意することで拡張性を高めている。 extensions.confではこれらのDialplan Applicationsを組み合わせながら処理をカスタマイズしていく。
また、Dialplan Applicationsと似た機能にDialplan Functionsがある。 両者の違いはAsterisk Dialplan Functionsに下記のように書かれている。 ここでchannelとは「呼」や「コール」とも呼ばれる概念で、1つの通話と1つのchannelは1:1で紐づいている。
Compared to Dialplan Applications:
Dialplan Functions tend to be geared towards manipulating channel data and
attributes as well as providing general tools for manipulating data in
variables and expressions, whether they are channel related or not.
Dialplan Applications tend to take over the channel and provide more
complex features to the channel.
extensions.conf だけでは静的な処理しかできないため、動的にAsteriskを制御する方法としてAGI、ARI、AMIが用意されている。
AGI
AGI(Asterisk Gateway Interface)はextensions.confからスクリプトを呼び出せる機能のこと。 スクリプトを用意する代わりにTCPサーバーを立てておくFastAGIもある。
AGIではAGI Commandsの実行が可能。 また、このコマンドのうち、GET FULL VARIABLEコマンドでDialplan Functionsを、EXECコマンドでDialplan Applicationsを利用できる。
整理しておくとAGIではAGIコマンド、Dialplan Applications、Dialplan Functionsの利用ができる。 これらはそれぞれ下記のコマンドで利用可能なものを確認できる。
