Hi, @bwindels

@efazenda what is the url of your widget? Can we use it to try and reproduce your issue?

It's a private room but here a new one where the problem is similar.

URL of the conference room on out BigBlueButton instance.
https://conference.csti.ch/b/faz-ttj-xkw

It you need more information don't hesitate to ask.

Best Regards, Edouard Fazenda.

Sorry for the late reply, was on holiday 🙂

I can reproduce this. Thanks for the test URL, it was quite useful. I get an error in the JS console in Chromium:

ERROR: clientLogger: Error getting microphone - {NotAllowedError: Permission denied}

which comes from here in BBB's source code.

Element does allow widget iframes microphone and camera permissions, however it looks like the widget's inner iframe does not have the microphone or camera properties, which would block access to the iframe. I'll have a play around and see if I can modify scalar's iframe to allow this.

[anoadragon453]

Adding the camera; microphone feature policies to the inner iframe has allowed the widget to request camera/microphone permissions :)

A fix is now in development - will keep you posted.

sip.Inviter | Session.getOffer: SDH getDescription rejected... sip.js:9594:25

@danielfomin96 Judging by the logs I think you're attempting a SIP call instead of a BigBlueButton one?

This issue was something specifically broken in the BigBlueButton widget. If you're having issues with SIP calling in Element, please open a new issue 🙂
