freeswitch - freeswitch 在呼叫呼叫​​中心的代理期间至少 60 秒无法接收 b-leg dtmf

Question

正如标题所说，我从 b-leg 获取 dtmf 数字时遇到问题。当我在呼叫中心呼叫队列时，可以桥接两条腿。但是当我在我的b-leg电话上按'*7'时它没有任何反应。

这是拨号方案：

    <extension name="Queue90">
        <condition field="destination_number" expression="^90$">
            <action application="bind_meta_app" data="7 ab s execute_extension::att_xfer XML features"/>
            <action application="callcenter" data="90"/>
        </condition>
    </extension>

而且，这是控制台日志：

但我可以从我的电话中捕获 dtmf 数据包。这对我来说太奇怪了。有人可以告诉我为什么吗？

我现在知道如何解决它。这是由于freeswitch set 2833 dtmf send payload to 105 recv payload到101，但电话仍然发送105 dtmf payload类型到freeswitch。我将 sip_profiles/internal.xml 中的“rfc2833-pt”修改为“105”，它对我有用。
