I`m trying this trick in dialplan:

exten => 100,1,DBPut(TEST/test=${EXTEN})
exten => 100,2,Dial(MGCP/aaln/4 at aaa,,t)

exten => 160,1,Dial(SIP/160,,t)
exten => 160,102,Wait(5)
exten => 160,103,DBget(a=TEST/test)
exten => 160,104,Dial(Local/${a})

I call from other phone extension 100, then from this phone I transfer 
it to a busy 160, and immedeatly hangup 100.  but I get only this on 
console:

    -- Executing Wait("MGCP/aaln/3 at aaa-1", "10") in new stack
    -- Endpoint 'aaln/4 at aaa-1' observed 'hu'
    -- MGCP handle_request(aaln/4 at aaa-1) ast_channel already destroyed
    -- MGCP handle_request(aaln/4 at aaa) set vmwi(-)
    -- Executing DBget("MGCP/aaln/3 at aaa-1", "a=TEST/test") in new stack
    -- DBget: varname=a, family=TEST, key=test
    -- DBget: set variable a to 100
    -- Executing Dial("MGCP/aaln/3 at aaa-1", "Local/100") in new stack
  == Everyone is busy at this time

the exten 100 is mgcp/aaln/4 and the calling channel is mgcp/aaln/3

why is it busy?
