When I join a meeting with the WEB SDK i get to following error on pressing the “Phone Call” button:

```
Uncaught TypeError: Cannot read property 'label' of null
    at zoom-meeting-1.8.3.min.js:2
    at Td (react-dom.min.js:82)
    at hi (react-dom.min.js:102)
    at Qg (react-dom.min.js:144)
    at Rg (react-dom.min.js:145)
    at Sc (react-dom.min.js:158)
    at Z (react-dom.min.js:156)
    at ah (react-dom.min.js:159)
    at xf (react-dom.min.js:40)

```

Also I can’t disable the Phone Call button via the ZoomMtg.init options. I tried as such:  
disableCallOut: true  
disableJoinAudio: true

Finally I tried to switch between versions 1.8.0 1.8.1 and 1.8.3, but that didn’t solve the problem

Thanks,

Hey @triluvio,

Thank you! We have made some fixes relating to the phone button in Web SDK version 1.8.5. Can you please try upgrading and see if you experience the issue?

> [@(ACTION REQUIRED) Web SDK update version 1.8.5](https://devforum.zoom.us/t/action-required-web-sdk-update-version-1-8-5/39004):
>
> Hello Zoom Developers, here are the updates for the Web SDK version 1.8.5 release: Please note that as of January 10th, all older versions of the Web SDK (versions 1.8.3 and below) will no longer have computer audio functionality within meetings. Please upgrade to version 1.8.5 or above to avoid service disruption. To complete alignment with Zoom’s security initiative, including the new AES 256-bit GCM encryption, we will disable un-encrypted audio within meetings that are not using AES 256-bit…

Thanks,  
Tommy
