简单视频会议软件

video conferencing. Like most of our services, it is free of charge. It is built on a reliable open-source solution, it is mostly based on WebRTC, which allows communicating in the browser by just clicking on a link. Below we’ll tell you more about its features and some of the problems we’ve run into.视频会议 。 像我们的大多数服务一样，它是免费的。 它基于可靠的开源解决方案构建，主要基于WebRTC，该WebRTC允许通过单击链接即可在浏览器中进行通信。 下面我们将向您详细介绍其功能以及我们遇到的一些问题。

At the beginning of March, we have decided to offer our clients a video conferencing tool. We’ve tested a few options and, in order to speed up its launch and maximize the features, we went with an open-source solution Jitsi meet. There is a ton of materials about it already, so we will not go into detail. But we, of course, did not just implement it, but added a few features and optimized.

3月初，我们决定为客户提供视频会议工具。 我们已经测试了一些选项，并且为了加速其发布和最大化功能，我们选择了开源解决方案Jitsi Meet。 已经有大量的材料，因此我们不再赘述。 但是，我们当然不仅实现了它，还添加了一些功能并对其进行了优化。

可用功能列表 (List of available features)

We offer standard jitsi features + some tweaks and integration with an existing phone system.

我们提供标准的jitsi功能+一些调整和与现有电话系统的集成。

• High-quality WebRTC calls 高质量的WebRTC呼叫
• SSL encryption (not yet p2p, but maybe soon to come)SSL加密(尚未p2p，但可能即将推出)
• iOS/Android appsiOS / Android应用
• Increased conference security: link and password creation in Zadarma personal account (the one who creates is the moderator). So not like in jitsi, where the one who logs in first is the moderator增强会议安全性：在Zadarma个人帐户中创建链接和密码(创建者是主持人)。 因此，与在jitsi中不同，首先登录的是主持人
• Simple text chat in the conference 会议中的简单文字聊天
• Screenshare and YouTube live streaming and recording屏幕共享和YouTube实时流媒体和录制
• Integration with IP-telephony: ability to connect to conference via phone 与IP电话集成：可以通过电话连接到会议

如何使用它？ (How to use it?)

Really simple:

真的很简单：

• Go to video conferencing page (register if you don’t have an account)

  转到视频会议页面( 注册 ，如果你没有一个帐户)

• Create a room (we recommend assigning a password) 创建一个房间(我们建议分配一个密码)
• Share a link and chat away分享链接并聊天

For mobile devices you would need to download an app (available in AppStore and Google Play), and for a computer – opening a link in a browser will be enough. If you do not have internet access, you can join via phone and enter conference PIN.

对于移动设备，您需要下载一个应用程序(可在AppStore和Google Play中获得)，对于计算机，只需在浏览器中打开链接即可。 如果您无法访问互联网，则可以通过电话加入并输入会议PIN。

我为什么需要你？ 我自己动手做 (Why do I need you? I’ll implement Jitsi myself )

If you have resources and desire, why not? But the first thing you need to pay attention to is Jitsi openness. If you are using conferencing for business – it might not work. Jitsi creates conference through any link, moderator right and password creation are assigned to the first one to sign in.

如果您有资源和渴望，为什么不呢？ 但是首先要注意的是Jitsi开放性。 如果您将会议用于商务活动，则可能无法正常工作。 Jitsi通过任何链接创建会议，主持人权限和密码创建分配给第一个登录。

So it is easier to create a server “for everyone” than for yourself. But then you can choose one of services, there are already several open jitsi servers.

因此，“为所有人”创建服务器要比为自己创建服务器容易。 但是，您可以选择其中一种服务，已经有几个开放的jitsi服务器。

However, «for everyone” servers may experience troubles with load and balance. In our case, we have already solved load and scale problem (already implemented on several servers, if needed additional can be added within a couple hours).

但是，“对于所有人”服务器可能会在负载和平衡方面遇到麻烦。 在我们的案例中，我们已经解决了负载和规模问题(已经在多台服务器上实现，如果需要，可以在几个小时内添加其他服务器)。

Also, to avoid peak overloads from unregistered users there are limits.

此外，为避免未注册用户造成的峰值过载，还有一些限制。

有什么限制？ (What limits?)

Video conference limits:

视频会议限制：

• 1 room up to 10 participants for registered users1个房间，最多可容纳10位参与者(注册用户)
• 2 rooms each up to 20 participants after topping up your account balance (at least once in six months) – so for existing Zadarma clients 充值后，每个房间最多2个房间，最多可容纳20个参与者(六个月至少一次)–对于现有Zadarma客户
• 5 rooms each up to 50 participants for clients with Office bundle 5个房间，最多可容纳50位参与者(带Office捆绑包)
• 10 rooms each up to 100 participants for clients with Corporation bundle 10个房间，每间最多可容纳100位参与者，可享受公司捆绑服务的客户

But most browsers and devices can adequately display 60-70 people in a conference. For larger numbers, we recommend live streaming to YouTube or utilize integration VoIP.

但是大多数浏览器和设备可以在会议中充分显示60-70人。 对于大量用户，我们建议向YouTube直播或使用集成VoIP。

电话整合 (Telephony integration )

With all additional services, Zadarma is first and foremost a telecom provider. So, naturally, we’ve added an integration with VoIP.

凭借所有其他服务，Zadarma首先是电信提供商。 因此，自然地，我们添加了与VoIP的集成。

With this integration, you can combine audio and video conferences (both via Zadarma PBX or your own PBX if you have it). You just need to dial 00300 and enter PIN displayed under video conference room link.

通过这种集成，您可以将音频和视频会议(通过Zadarma PBX或您自己的PBX进行组合)组合在一起。 您只需要拨打00300并输入视频会议室链接下方显示的PIN码即可。

In Zadarma PBX you can create an audio conference (by dialing 000) and adding a “participant” with a number 00300.

在Zadarma PBX中，您可以创建音频会议(通过拨打000)并添加带有号码00300的“参与者”。

You can also join the conference by calling a phone number (numbers in 40 countries are available).

您也可以通过拨打电话参加会议(可以使用40个国家/地区的电话号码)。

你为什么需要它？ (Why do you need it?)

It is not the first or the last service offered by Zadarma for free. Before we’ve offered PBX, CRM, Callback widget, Call tracking, and Click-to-call widgets. There is only one reason – attracting clients in the hope that part of them will start using paid services (virtual numbers and outgoing calls). So instead of investing in advertising, we are developing free products. Free services have already helped us to attract over 1.6 million clients, and the successful model keeps on working.

它不是Zadarma免费提供的第一个或最后一个服务。 在我们提供PBX ， CRM ，回调小部件，呼叫跟踪和点击通话小部件之前。 只有一个原因–吸引客户希望他们的一部分将开始使用付费服务(虚拟号码和去电)。 因此，我们不投资广告，而是开发免费产品。 免费服务已经帮助我们吸引了超过160万客户，并且成功的模式一直在起作用。

聚苯乙烯 (P.S.)

As you can see, we’ve already been through balancing, fault tolerance, additional security. Aside from that, there was quite some debugging and small twitching. We’ve also tried to make VoIP integration as convenient as possible. App moderation for both iOS and Android had become quite a hassle (but it was worth it, Android downloads surpassed 1000 in one week).

如您所见，我们已经经历了平衡，容错和额外的安全性。 除此之外，还有很多调试和小的抽搐。 我们还尝试使VoIP集成尽可能方便。 适用于iOS和Android的应用程序审核工作非常麻烦(但值得，Android下载量在一周内超过了1000次)。

You can try and set up your server or use our free video conferencing.

您可以尝试设置服务器或使用我们的免费视频会议。
