nachdem ich jetzt schon einige Tage mitlese, habe ich heute was festgestellt, was evtl. für alle interessant sein könnte.
Ich habe vorhin mal auf dem Server von Draytek geschaut und gesehen, dass es seit dem 2.6.04 eine neue Firmware gibt. Es handelt sich dabei um die 2.51. Aus dem Changelog geht folgendes hervor:

Ich habe die Firmware auch gleich ausprobiert (ist übrigens englisch!) und kann jetzt auf jeden Fall schonmal auch mit meinem BT-101 über Siptel raus telefonieren und werde auch auf der anderen Seite gehört. Das "Ewig-klingeln" Problem scheint aber immer noch zu bestehen.
Mit der alten 2.3.12 Firmware (IIRC) wurde man noch nicht mal gehört. Da scheint es also wirklich eine Besserung zu geben.

Hoffe ich kann euch damit helfen.
