Twilio起源呼叫问题 - 间歇性传入问题

时间：2016-07-04 21:14:39

标签： twilio asterisk sip sip-server freepbx

我正在尝试在我的Asterisk / Freepbx实例上设置Twilio Elastic SIP Trunking并且很难设置可靠的发起（终止工作非常好）。

背景 - 我按照twilio指南完成了所有设置，在freepbx和stackoverflow上发布了很多论坛帖子，而且大部分都是一个有效的设置。

  1. 来自分机/ pbx的出站 - 效果非常好，清晰度很高。
  2. 从PSTN到Twilio的入站号码：我先听到一些短铃声，然后是几声长铃声，它'可能'最终会拨打我的分机号码。呼叫到达我的分机的时间的25％（并且从一个Twilio白名单IP成功和随机地，不一定是相同的IP）。 75％的时间呼叫与哔声断开，呼叫无法连接等消息。
  3. 当我使用“拨打测试呼叫”按钮从Twilio'Origination'设置页面拨打电话时，该呼叫是即时的，并且工作正常。

    4. 在上面的＃2中，我注意到我听到的每个戒指都在Twilio中有一个“失败”的日志。我无法从日志中解读太多信息（没有任何401,403等）。有人可以帮忙吗？为什么＃3总是有效（Twilio的测试呼叫按钮）？

    以下是失败电话的Twilio日志：
