Steps to reproduce


Repro Steps:

I’m trying to use Edge’s ORTC in order to have real-time communication with other web browsers. I’ve successfuly made this work using peer-to-peer connections but I’m having problems after adding a gateway in between.

The DTLS handshake for some reason fails when I start the call using Edge (controlling), I’ve turn on wireshark to see if any DTLS messages were being executed but none was “sniffed” (this can be an wireshark issue though). If I answer from Edge (controlled) the connection works (even with the gateway in between).

It’s important to notice that the ICE Connection is successfuly established in every case, it seems that by some reason Edge doesn’t initiate the DTLS handshake and I can’t understand what is the trigger point (I even get the “checking” status on the “ondtlsstatechange” event for the dtls transport object). After about 30 seconds the failed event triggers!

Expected Results:

The connection should be successfuly established.

Actual Results:

    • Thank you for your feedback! 

      The repro info you provided is not sufficient for our engineering team to investigate.  We don’t have access to the specific “gateway” mentioned in the repro, and don’t have access to the specific repro app either.  Please feel free to contact my colleague directly (ShijunS@microsoft.com).  And he can work with you to understand the problem, and then reactivate the bug when needed.

      All the best,
