Have you enabled Brekeke PBX to use WebRTC?

Which WebRTC client are you using?

Hi Mohney,

Yes, I enable the WebRTC and make the settings on the phone type, the extension connected without issue but my problem is when we sent an INVITE UDP to the WebRTC extension, the invite is going without the DTLS finger print from the Brekeke to the Chrome client.
I'm using Chrome WebRTC client.

Thanks,

It depends on a SIP UAC whether it supports DTLS or not.

If you send a call through Brekeke PBX, the PBX can insert DTLS behalf of UAC.

Hi tazevedo,

Does the call from UAC go through Brekeke PBX?

I think if you already configured WebRTC settings, PBX can insert DTLS without any other additional settings.

Thank you.
