Ich habe bei allen Telefonanlagen das Logging auf CF Karte eingeschaltet. Bei einer Fehlersuche ist mir im Logging folgendes aufgefalle:

meine frage ist, was verursacht diese Fehlermeldung?

20180517-144010 CALL 10 B:Rel 17:Gabi+***********@Goerzwerk->081413536*** / RS1:17:SIP->TONE:081413536***: Cause: Resources unavailable, unspecified

Hat jemad so etwas bereits erlebt?
