Gegenstelle hört nichts

[robinsonR]

Ich habe in einer FBF 7270 als Internet-Rufnummer eine Nebenstelle meines Asterisk eingetragen (ähnliche Konfiguration funktioniert bei einem Kollegen einwandfrei). Ich kann dann zwar sowohl von Telefonen an der Fritzbox Nebenstellen des Asterisk anrufen und umgekehrt, es wird aber keine Sprache übertragen, ich höre also nichts. Auf der FBF bekomme ich diese Einträge bei «Sprachübertragung»:

und auf der Asterisk-Seite sowas:

Wobei 51 die Nebenstelle des Asterisk und 82 die der Fritzbox ist.
