Continuous ringing
GNOME Calls keeps sometimes ringing after accepting the call. Maybe this is related to a missed call, that did not fully come through (due delays?), and the connection was broken for the other side, after which the other side called immediately again. I see this mainly by calls I get to authenticate from Microsoft. This issue does not always happen, and I do not know how to reproduce it.
See also the Purism Librem 5 forum for a discussion about this issue.
Here is a log from my phone when this happened: continuous_ringing.log
