You're right, unfortunately. ;-(
If I execute ChanIsAvail on a physically disconnected
port then I get:

    -- Executing ChanIsAvail("SIP/4053-0823fc18",
"Zap/32&Zap/33&Zap/34&Zap/35") in new stack
    -- Hungup 'Zap/32-1'
    -- Executing NoOp("SIP/4053-0823fc18", "Zap/32-1")
in new stack
    -- Executing NoOp("SIP/4053-0823fc18", "0") in new
stack

${AVAILSTATUS} is 0 AST_DEVICE_UNKNOWN - "Unknown";
channel is valid, but unknown state.
