Hallo Community,

ich habe leider ein kleines Problem mit einer Telefonanlage (Panasonic NS700) und O2 Trunk. Vor eigentlich genau 2 Monante wurde von Telekom Trunk auf O2 Trunk umgestellt und ich habe die Telefonnalge dementsprechend konfiguriert, diese lief bis diesen Dienstag problemlos. Jetzt auf einmal herrscht das Problem, das eingehende Anrufe nach etwa genau 30 Sekunden wieder getrennt werden. Ausgehend stellt gar kein Problem dar.

Ich habe jetzt soweit rausgefunden, dass es wohl ein NAT oder re-invite Problem sein könnte. An der Telefonanlage wurde aber seit der Einrichtung nichts mehr geändert. NAT Keep Alive steht auf 20s und sollte wohl auch passen.

Ich habe jetzt ein Wireshark Auszug von einem Telefonat was nach 30 Sekunden abbricht. Nur bei den Wireshark Logs bin ich noch nicht 100%ig fit und hoffe ihr findet hier einen Lösungsansatz.

Nur bei den Wireshark Logs bin ich noch nicht 100%ig fit
Bei Formatierungen und Datenschutz auch nicht.

Ich sehe in deinem Auszug einige INVITE aber kein ACK, sodass wahrscheinlich am Ende mit BYE bzw. 405 Method not allowed aufgegeben wird. Da ich die Anlagen von Panasonic nicht kenne, kann ich da nicht mehr zu sagen. Ein Problem mit NAT schließe ich aber aus.

Einen Schuss ins Blaue möchte ich aber wagen: aktiver SIP ALG auf dem Router.
 
Hatte wohl noch den unbearbeiteten Text in der Zwischenablage. Danke für den Hinweis.

SIP ALG hatte ich auch gelesen, nur der Router ist von der O2 und wir haben kein Zugang zu. Kann man dies irgendwie prüfen?
 
Wenn ihr keinen Zugang habt, lässt sich anhand vom Modell nur nachsehen, ob SIP ALG grundsätzlich drin ist oder nicht. Ob man von außen erkennen kann, ob das Ding an oder aus ist, kann ich nicht sagen.
 
Kostenlos!
