是的，Asterisk 是一個複雜的系統，整合了諸多資源，而這些資源使用系統中各種不同的方式。底下的解說採用 Ubuntu 為例。
[組態檔]
Asterisk 的組態檔預設都是放在 /etc/asterisk/ ，底下是幾個比較重要的設定
extensions.conf manager.conf sip.conf voicemail.conf asterisk.conf
在最後面會有這幾個檔的範例
[模組]
根據 asterisk.conf 中的設定，模組是放在 astmoddir => /usr/lib/asterisk/modules 中
需要注意的是，新舊版本的模組是不相容的，建議把舊的模組刪除或是備份。
[資源檔]
音樂檔(像 Music oh Hold(MOH)) 照 asterisk.conf 的設定，是放在 /usr/share/asterisk/moh 中。這邊要注意的是要依據設定檔來找，有很大可能也會放在 /var/lib/asterisk/moh 中
[spool]
spool 通常放在 /var/spool/asterisk 中，這目錄放的檔案主要是需要其他工具使用，例如 mail, printer 等等
[記錄]
記錄檔通常放 /var/log/asterisk 中，種類很多，包括 CDR, CEL, debug log, queue log, mesages, error 等等等
