Special services for video conferencing
There are quite a large number of specialized services on the Russian market that were developed specifically for video conferencing.

Yandex Telemost
Yandex Telemost is one of the popular domestic analogues of zoom, part of the jamaica phone number list Yandex 360 virtual office. The service allows you to hold free video conferences for teams of up to 40 people. The time of calls is unlimited. The recording of the meeting can be saved to your computer.

Telemost has the basic tools needed for video conferencing. For example, screen sharing, chat, and file sharing. But there are also some features that need to be taken into account in advance:

Only the owner of a Yandex Mail account can create a video meeting. Anyone can participate in the meeting, even without registration.
Conference recording in Yandex browser and Google Chrome will be limited to 30 minutes. In Mozilla Firefox and Chromium browsers, it will not be possible to record a call at all. If you need a recording longer than 30 minutes, you will have to download the application.
In screen sharing mode, the speaker is not visible. This is sometimes important for training purposes.
The video will be saved in WebM format. If editing is required later, the format will need to be converted to Mp4.
For video conferences with more than 40 people, you need to purchase a paid subscription to Yandex 360.
Yandex Telemost is suitable for teams that usually call in small groups or one-on-one, and for whom video calls are sufficient.
