使用lua的Asterisk挂机处理程序

我正在尝试在我的拨号计划中添加一个挂机处理程序，以捕获拨打多个分机的未接来电。但不幸的是，我的挂机处理程序根本没有执行。 以下是我的extensions.lua

CONSOLE = "Console/dsp" -- 演示用控制台界面
IAXINFO = "guest"       -- IAXtel用户名/密码
TRUNK = "SIP"

GSMTRUNK = "Dongle/dongle0/"
PRITRUNK = "DAHDI/g0/"
TRUNKMSD = 1
local inspect = require ('inspect')
--从这里开始我们的逻辑是Rajesh
function dialtomobind(number)
        app.Dial(GSMTRUNK..number, 50,'egb(add-hangup-handler^'..number..'^1)')
        local dialstatus = channel['DIALSTATUS']:get()
        app.NoOp('DIAL STATUS:'..dialstatus)
        app.Hangup(16)
end

function add_hangup_handler(context, extension)
        channel['hangup_handler_push']='hangup-handlers,s,1'
        app.NoOp('pre-dial handler, Adding Hangup Handler'..channel['hangup_handler_push']:get())
        app.Return()
end

function h_handler(context, extension)
        app.NoOp('After Hangup:'..extension)
        --app.DumpChan(3)
end

function directdialing(c,e)
        app.Answer(5)
        app.Playback('tt-monkeys')
        dialtomobind(string.sub(e, 4))
        app.Hangup(16)
end

function hangup_handler_1(c,e)
        --channel['hangup_handler_push']
        app.NoOp('Hangup Handler 1执行')
        app.Return()
end

extensions = {
        ['from-internal-sip']={
                ['h']=h_handler;
                ['_500XXXXXXXXXX']=directdialing;
        };
        ['dongle_incoming']={
                ['_.']=gsm_dongle_handler;
        };
        ['add-hangup-handler']={
                ['_.']=add_hangup_handler;
        };
        ['hangup-handlers']={
                ['_.']=hangup_handler_1;
        };
}
