1:1 Call Gives An ICE Error

2. Initiate a voice or video call
3. Be shown this error message:

[t3chguy]

@TheDarkula please use the prescribed mechanism for sending logs so it goes through the appropriate parsers. I don't want to have to manually unpick the stack traces.

[t3chguy]

It works fine for me on official Element Desktop on macOS. The call goes through and rings on both sides.

Seems like an issue specific to either the community maintained package which you are using or your setup.

[TheDarkula]

@t3chguy I am happy to send over a rageshake.tar file, as long as you are happy with me anonymising personal information in it.

[t3chguy]

@TheDarkula you're welcome to use the rageshake yourself to figure out the problem, otherwise we only tend to want submissions via the rageshake server as it does additional processing for us which I'd not have the time to do manually.

[TheDarkula]

@t3chguy I understand that you want a parser to read through things for you. Is there a reason why the rageshake mechanism does not anonymise things like usernames and homeserver domains?

[t3chguy]

Presumably because those details can be relevant for correlating 2 sides of a rageshake, or even up to 4 sides if federation is involved
