Verbindungen brechen ab bzw nach iniger Zeit forbidden bei Telekom Voip

Support
1

Guten Abend zusammen,
seit einiger Zeit gibt es Probleme mit 2 Telekom Anschlüßen. Beide sind in der MB-Anlage eingerichtet und funktionierten eine Zeit lang ohne Probleme. Seit ca 6 Wochen gibts aber Probleme.
Die Anlage läuft Virtuell. Das Internet wird über eine 7490 geregelt. Nach der 7490 kommt eine Firewall mit Portfreigabe.
Nach einem Reboot der MB kann man meistens einige Zeit telefonieren. nach Durchschnittlich 65 Minuten bricht dann die Verbindung ab. Manchmal nach 3 Minuten, manchmal aber auch erst anch 3 Stunden.
In einigen Fällen kann man direkt wieder extern Anrufen. Manchmal kommt direkt nach diesem Fehler beim wählen “forbidden” im Telefon.
Meistens kommt dieses forbidden auch, ohne ein vorheriges Telefonat.
Ein Reboot der Anlage hilft für maximal 36 Stunden.
Dieser Fehler tritt auch mit einer anderen Telefonanlage auf.
Beide funktionierten längere Zeit ohne Probleme.
An der Config und am Setup wurde nichts geändert.
Sipgate funktioniert korrekt.
Ausgabe “asterisk -r”

Hallo,

wir haben seit ca. 2 Tagen genau das gleiche Problem, schau dir das hier mal an:

Hi,

wie in dem Beitrag angemerkt, ist es sichtig den Telekom DNS (auch den von der Telekom am Anschluss bereitgestellten “lokal zuständigen” DNS) zu verwenden, entweder direkt oder über den Router. Leider ist die Telekom hier sehr “dynamisch”, wodurch sich ein alter Host relativ zügig nicht mehr zuständig fühlt.
Auch liefern wir ab 17.10 bzw 15.12 ein im default bei Telekom Ämter Nutzung aktiviertes Script mit, welches diese IP Wechsel prüft und dann einen “sip reload” absetzt, wodurch das Problem nicht mehr auftreten sollte.

Grüße,
Steve

Die änderung vom DNS hat mir nichts gebracht. Aber danke Steve. ein “sip reload” behebt das Problem. Dies kann auch wärend eines Gesprächs gemacht werden, ohne das die Verbindung weg bricht. Von daher ist ein Cronjob nun bis auf weiteres mein Workaround :slightly_smiling_face:
Gruß und danke für eure bisherige Hilfe.
