Call Kit is a full-featured voice + video component, which enables one-on-one and group calls with just a few lines of code.

Once you integrate the Call Kit, you can embed it in any website or app, and you can also add or remove various in-call features by customizing parameters.

When do you need the Call Kit

If you want to integrate one-on-one or group voice/video calls ASAP and consider speed or efficiency as the first priority, then the Call Kit is your best choice:

  1. Adaptive to PCs and mobile devices, and handles complex network and device exceptions in a standard way, with no more complex concepts to be learned and understood.
