Attention: WebRTC SDK users - please upgrade to v0.4.1


The latest version of Google Chrome, version 57, has introduced a change that causes older versions of RingCentral WebRTC SDK to fail when initiating calls.

Google has started to auto-deploy version 57 this past weekend. While we estimate less than 1% of the browser population is currently on Chrome 57, we expect this to increase quickly.


We have released v0.4.1 of the RingCentral WebRTC SDK which addresses this issue

We strongly recommend that you incorporate our updated WebRTC SDK ASAP so your users do not see service interruption:
