vxml自定义队列传输

Question

我要转移到线路号，而无需在此线路上设置跟进呼叫转移。

以下是一些代码：

<?xml version="1.0" ?>
<vxml version="2.1" xmlns="http://www.w3.org/2001/vxml" xml:lang="fr-FR">
<var name="destinations" expr="['0033xxxxxxxxx', '0033xxxxxxxxx']"/>

<form id="transferCall">
    <var name="currentDestination" expr="'number/'+destinations.shift()" />
    <transfer name="transferResult" type="consultation" destexpr="currentDestination" connecttimeout='20s'>
        <prompt>
            <audio src="./files/samples/waiting.wav"/>
        </prompt>
        <filled>
            <if cond="transferResult=='noanswer'" />
                <assign name="transferDuration" expr="transferDuration+20" />
                <goto next="#transferCall" />
            <elseif cond="transferResult=='busy'" />
                <assign name="transferDuration" expr="transferDuration+20" />
                <goto next="#transferCall" />
            <else/>
                <prompt> <value expr="transferResult" /> </prompt>
            </if>
        </filled>
        <catch event="connection.disconnect.hangup">

        </catch>
    </transfer>
</form>

谢谢
