如何解决在 Twilio 中终止 Pexip
我们正在尝试设置我们的 Pexip 帐户以向我们的 Twilio 帐户拨打电话。我们成功将 Pexip 连接到 Twilio，但收到“需要 407 代理身份验证”。有没有人成功地让他们的 Pexip 帐户通过 SIP 呼叫 Twilio？

为了保护无辜者而更改了电话号码和 IP 地址。
我们的 Twilio 帐户的 IP ACL 中确实列出了我们的 Pexip IP 地址。
解决方法
您是否在弹性 SIP 中继上定义了凭证列表？ 407 Proxy Authentication required 要求您的 SIP 用户代理使用其身份验证凭据（用户名和密码）进行响应。
