Since they are actually accepting the call, rather than blocking it, then filtering to a general Error Message, SipBroker cannot determine whether the answering party is the person you wanted or a voicemail, it just sees that a connetion was established with the server (analogically it cannot tell if the right person answered, only that it got an answer)
Something similar happens trying to place calls to PhoneGnome users (web account only) without a PhoneGnome Box....
