mISDN und sporadisches CHANUNAVAIL

[steffen_77]

Hallo Forum,

ich habe das Problem eine Asterisk-Installation mit einem Siemens Gigaset CX470ISDN sauber zum Laufen zubekommen.

Die Umgebung:
neu aufgesetztes Asterisk 1.4.18 mit mISDN 1_1_7_2 auf Debian 4.0
Das Gigaset hängt an einem NT-konfiguriertem Port einer 4-Port Karte (hfcmulti-Treiber).

Das Problem:
Bei Anruf auf das Gigaset kommt es sporadisch zu einer Meldung DIALSTATUS = CHANUNAVAIL. Der Anrufer landet daraufhin in der Voicebox des Nutzers - am DECT-Mobilteil wird ein laufendes Gespräch signalisiert.
Der Zustand lässt sich durch sofortiges erneutes Anrufen reproduzieren. Wartet man einige Minuten und versucht es erneut, kommt wieder problemlos ein Gespräch zustande.
Das Problem lässt sich auch mit einem "normalen" ISDN-Telefon nachvollziehen, kann also nicht am Gigaset liegen.

Im Forum hab ich Beiträge mit ähnlichen Effekten bei "älteren" Installation (asterisk 1.2) entdeckt, die sich nur durch einen Neustart von mISDN behoben werden können.
Hat jemand ähnliche Erfahrungen gemacht und /oder sogar einen Lösungsweg?
