i am not sure how is call handler working. I created a profile under call handler, then i went to a subscriber to associate the greeting to this call handler. As a result, when i dial the extension via the unity hunt group, instead of hearing the call handler profile greeting and allow me to leave a voice mail, unity tells me that " sorry, Test A is busy or is not answer, i am sorry i could not recognise that's a valid entry ". Even after i had removed the call handler greeting. The outcome is still the same.
