Some more things missing from Voice that are quite important:
- Pull call - or the ability to change from desktop to mobile/vice-versa
- Transfer calls to PSTN - the ability to transfer to an off-net (non-PhoneSystem) number
- iOS CallKit Integration including CarPlay
- Dialpad in mobile by default instead of having tap 4 things to start to dial a number
- Dial from command bar in desktop client
- Dialpad focus - when on the Calls tab, the text box for the phone number should have focus by default
- Improvements with Click To Dial - some protocols work, others don't - ability to specify and take over: tel: dial: callto: ucdial: sip: skype: and (wishful thinking) tapi interception - with number formatting auto-correction would be a dream
Also, ever since adding a Polycom phone to my account, and we are in "Teams Only" mode, some of my colleagues see me listed as "Using Skype for Business" on occasion.
Lastly, I've seen some strangeness with incoming calls:
- a call was coming in, ringing on one laptop, not on my mobile device
- a call came in, I clicked to answer in Teams right away and the call disappeared - have to let it ring a full ring before answering so that the calls don't disappear
