+===== Dokumentation =====
+Hinweise zum Release **14** finden sich auf der **[[https://wiki.asterisk.org/wiki/display/AST/Asterisk+14+Documentation|Dokumentationsseite]]** von Asterisk. Alle Neuerungen des aktuellen Release finden sich auf der Seite **[[https://wiki.asterisk.org/wiki/display/AST/New+in+14| New in 14]]**. Die Seite **[[https://wiki.asterisk.org/wiki/display/AST/Asterisk+14+Command+Reference|Asterisk 14 Command Reference]]** beinhaltet weitere Unterseiten zu den Kommandos und APIs.
 ===== Installation =====
-Die Installation von Asterisk unetr CentOS 7 könnte man an Hand der **[[http://downloads.asterisk.org/pub/telephony/asterisk/|Programm-Sourcen]]** vornehmen. Dazu müsste auf dem VoIP-Server aber unter anderem Entwicklungstools wie "//**gcc & Co**//" installiert werden; was natürlich auf einem Produktivsystem mehr als zweifelhaft ist und aus Sicherheitsüberlegungen heraus tunlichst vermieden werden sollte.

+  Created symlink from /etc/systemd/system/multi-user.target.wants/asterisk.service to /usr/lib/systemd/system/asterisk.service.
+Wollen wir prüfen ob der Autostart des Daemon richtig gesetzt wurde, fragen wir den Status entsprechend wie folgt ab.

+===== Anbindung an das VoIP-Netz der Telekom mit PJSIP =====
+==== Grundkonfiguration ====
+==== individuelle Rufnummer bei der abgehenden Wahl setzen ====
+Haben wir von unserem VoIP-Anbieter mehrere Rufnummern bekommen, so werden wir diese in aller regel einzelnen Endgeräten oder Diensten zuordnen wollen. Bei ankommenden Gesprächen haben wir diese Zuordnung über den Abschnitt **[telekom_in]** vorgenommen. Nun wollen wir aber auch je nach verwendeter internen Nebenstelle unseres Asterisk eine bestimmte Rufnummr **CLID**((**C**alling **L**ine **ID**entification)) als Absender nach extern verwenden und auch übertragen.
+Das was sich bei dem ein oder anderen höchstprofesssionellen Systemintegrator als unlösbare Herausforderunge bei einer VoIP-Anlage mit 3.000 Nebenstellen darstellen kann, gestaltet sich bei unserem Asterisk-Server als triviale Herausforderung. LOL
+Für die Zuordnung der internen Rufnummern zu den jeweiligen externen Absenderrufnummern bzw. PJSIP-Kanälen bedienen wir uns der Asterisk-eigenen Datenbank. Diese Datenbank erreichen wir über die Funktion **database**. Wir können damit z.B. unsere Registrierten Geräte abfragen.
