Google Chrome 麦克风问题 OpenVBX
我正在使用 Twilio 的 OpenVBX 电话软件，每次通话时 进入软件，我单击“应答”，它会弹出 Flash 对话框 盒子，但里面什么也没有。它在 Firefox 中完美运行，我只是更喜欢 使用 google chrome
这是我的屏幕截图：

I am using the OpenVBX phone software by Twilio and everytime a call
comes into the software and I click answer it pops up the flash dialog
box but nothing is there. It works perfect in firefox, I just prefer
to use google chrome

Assuming that you have flash installed do this:
Go to http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager02.html
Click the first tab (privacy) that shows a globe and an eye in the computer display. Make sure that you set to "always ask".
It is also possible that you set it to deny the first time it asked you. In this case, make sure you clear out all settings in flash and try again. If you selected deny and had remember settings checked, it won't ask you again.
我通过安装 SSL 证书并通过 HTTPS 运行 OpenVBX 解决了这个问题。 Chrome 似乎不允许不安全的网站访问麦克风，但当网站通过 HTTPS 提供服务时，它可以正常工作。
注意 如果您像我一样首先倾向于使用自签名 SSL 证书，请不要这样做。 Twilio 似乎不适用于自签名 SSL 证书。我能够使用 LetsEncrypt（这似乎是一个免费的 SSL 证书服务）并且运行良好并被 Twilio 接受。此外，还有一个很好的命令行工具，允许您只需几个控制台命令即可为您的 Web 服务器安装和配置 SSL。强烈推荐。
I was able to resolve this issue by installing a SSL certificate and running OpenVBX via HTTPS. It seems like Chrome doesn't allow access to the microphone for unsecured sites, but it works fine when the site is served via HTTPS.
note If like me your first inclination is to use a self-signed SSL certificate, don't. Twilio doesn't seem to work with self-signed SSL certificates. I was able to use letsencrypt (which appears to be a free SSL certificate service) and that worked fine and was accepted by Twilio. Additionally, there's a nice command line tool that allows you to get the SSL installed and configured for your web server with just a few console commands. Highly recommended.
