Changing account options regularly crashes app, can't register with TLS on VoIP.ms
Here's a list of things that don't seem to work :
Changing account settings regularly crashes the application. When the application resumes, the previous account settings are missing altogether. If I can add an account with a different name without having it crash, the original account shows back up again.
TLS registration doesn't work with VoIP.ms. When I'm on the Accounts page, the slider won't lock to online.
UDP registration will work with VoIP.ms (I can see the softphone registration on their website) but I don't get any audio. The call goes through because it records a blank voicemail, but I don't hear the announcement and it doesn't record my voice. I tried this in a Parallels Desktop VM on a Mac and audio works elsewhere in the VM (tested in the GNOME Settings-Sound in the VM).. Incoming calls won't ring in GNOME Calls, but will ring on other softphones. Might be a firewall issue - investigating.
FYI: I have tried enabling and disabling their option for "Encrypted SIP Traffic" and it doesn't seem to make a difference for either protocol, nor does it affect registration (I can see registration only for UDP, as described above, and it shows not encrypted, even when encrypted SIP traffic option is enabled).
Trying this on Fedora Workstation 35 with GNOME Calls from Flathub (installed new same day as this post).
