The team is working to address issues with call controls that occur for users running both Teams and Skype for Business. We will let you know when there is more to share.
For organizations that need call recording for compliance purposes, admins can set via policy. To see how this works for calling and meetings, please see https://docs.microsoft.com/MicrosoftTeams/teams-recording-policy.
1:1 convenience recording is currently on the teams backlog. We will share an updated here as soon as it is available.
Currently we have Teams defaulted to show you the first (up to five) channels ever created. If you want to add more channels to your left rail view, just click the ellipses next to the channel name and select “Favorite”. When you favorite the channel, it will then be “pinned” to your left rail under that team name.
Try that and let me know if that meets your needs!
Thank you for your continued feedback. We are currently working on this, and recently announced this feature for developers in Beta.
