proc init { } {
    global param1    
    set param1(interruptPrompt) true
    set param1(abortKey) #
    set param1(terminationKey) *
    set param1(maxDigits) 1
}
proc Start { } {
    global param1    

    infotag set med_language 1

    leg setupack leg_incoming
    leg proceeding leg_incoming
    leg connect leg_incoming

    leg collectdigits leg_incoming param1

    media play leg_incoming _you_have.au %a100
#    media play leg_incoming _you_have.au  - если так то всё работает

}
proc act_Cleanup { } {
    # прекратить звонок, положить трубку
    call close
}

requiredversion 2.0
init

set fsm(any_state,ev_disconnected)   "act_Cleanup  same_state"
set fsm(CALL_INIT,ev_setup_indication) "Start  same_state"

fsm define fsm CALL_INIT
