Hallo zusammen!
Ich habe leider ein Problem mit * im Zusammenhang mit dem Freenet ISDN Gateway.

Der Aufbau ist folgender:
DECT Telefon -> isdn -> ITA -> ethernet -> Asterisk -> ethernet -> Router ->Internet -> Freenet -> isdn -> Mein Handy.

Dabei funktioniert die Audioverbindung von Handy zu DECT nicht. Die andere Richtung funktioniert tadellos. Das interessante dabei ist, dass die RTP Daten von Freenet aber den Asterisk erreichen. Nur scheint dieser die zu verwerfen bzw. zu ignorieren.
Ansonsten funktioniert alles. Auch Gespräche über das Internet funktionieren. Mit Sipgate habe ich z.B. keine Probleme. Was mir dabei aufgefallen ist, dass bei Sipgate die IP von SIP Proxy und ISDN Gateway gleich sind. Bei Freenet sind diese verschieden. Ob das ein Grund ist?
Ich benutze die Version 1.2.7.1 auf einer Debian Kiste.
Habe auch mal im Bugtracker gesucht, allerdings nix passendes gefunden. Wobei ich mir da auch sicher bin dass ich nach evtl. nach den falschen Wörtern gesucht habe.


Hier mal die ganzen Einstellungen und Logs

Gibts jemanden der dazu eine Idee hat?
Habe beim Asterisk auch mal mit dem ethereal geloggt.
Die RTP's von Freenet kommen wirklich an und sind auch korrekt. Wenn ich die RTPs im ethereal extrahiere kann ich mir die auch anhören. Die Audiodaten kommen also ohne Probleme. Ansonsten funktioniert der Betrieb ja auch..nur Freenet macht ärger.
Ach ja..in der /etc/hosts ist der Eintrag "194.97.54.97 freenet.de" drin.

Niemand der eine Idee hat?
Sind die Einstellungen denn wenigstens richtig? Es würde mir schon sehr helfen wenn ich wüssste dass es nicht an mir liegt :D
Die Einstellungen habe ich aus dem Kurs angepasst. Hier und da sind ein paar Sachen aus dem Forum abgeguckt. Also eigentlich sollte die Konfiguration laufen...zumindest tut sie es anscheinend bei anderen.
