extension.conf ist falsch?

[networker ///]

Hallo,

vor einiger Zeit habe ich auf meiner Fritz Box den Asterisk installiert.
Die Anmeldung an dem externen Sip Server klappt einwandfrei.

Was leider nicht klappt, ist das Wählen einer Rufnummer.
Der Asterisk wählt immer nur die Rufnummern intern, also nie mit sip.1und1.de.
Dadurch kommt nie eine Verbindung nach außen zustande.

Ich habe hier mal einen Ausschnitt aus Sip debug:

Die Zeile “From” ist richtig, die Zeile “To” ist falsch.
Statt „XYZ.selfhost.eu” sollte “sip.1und1.de” stehen, da mein Provider 1und1 ist.
