Hello, just want to bring this question up again.
Is someone able to tell me, yes you can disable echo can on a per call basis and it is done this way, or not it is not possible, go away ... If it is not possible, why is that so ? Is there really no need to do this and i am totally mistaken? Generally receiving faxes works fine, but sometimes they break and i assume i might have something to do with echo can.
