ditch voip/sip

Hi,
I would like to bring up again the voip/sip issue. At least in my case it is impossible to connect using sip and I always end up dialing in using skype. I am wondering why sip is still the used method, especially given that ZOOM is used for other calls, even in the same group (e.g., did-resolution). I read in the mailing list archives that one of the reasons is audio recording, but AFAICT the audio recordings from most of the last meetings are missing (e.g., https://w3c-ccg.github.io/meetings/2020-05-19/audio.ogg  https://w3c-ccg.github.io/meetings/2020-04-21/audio.ogg https://w3c-ccg.github.io/meetings/2020-04-07/audio.ogg and many others)

Best,
Nikos
