We should be able to delete call history to keep the UI clean and usable.

When someone calls me, either internally or externally, and I'm on another call, the default behavior should send the call to voicemail after popping a notification and perhaps a subtle ring. This business of ringing more than once when I'm on a call is not helpful.

How about recording an audio call when initiating a Teams call, similar to how Skype for Business does ?

Teams needs an overview, reports, log about the usage of call queues with some basic features like number of calls answered, missed, average waiting time.
Also a list of answered and missed calls.

I have some small businesses who use or want to use Teams as their primary phone system and need AA/Call Queues for some very basic form of "customer service line" (although that term might overstate what they need) and they want to see missed calls so they can return the call.

When a PSTN user calls you on Microsoft Teams, if the number is in the address book I would like to be presented with the users name on the toast, not just the PSTN number. The same for call history or anywhere else a PSTN number appears in the client

In Skype for Business and most other phone systems, you can select to transfer a caller directly to voicemail (receptionists use this all the time). Teams does not have this option. It is very important for folks to not transfer to a ring-ring-ring experience if they simply need to leave a voicemail.

Add Click-to-dial for tel protocol. Our staff makes a lot of calls and has to copy and paste phone numbers right now. Would love to see an option for Teams to handle "tel:" protocol or another option for the ability to click-to-dial phone numbers within a web browser. This needs to be supported on Windows and Mac.

Our customer should have a function to switch an active call from the computer teams client to a mobile team client.

for example:
You answer a call at the PC/teamsclient and want to leave your desk and continue the call with your mobile phone/Teamsclient.

Normal call forwarding is not really useful in this case. It would be nice if there was something like a "Switch-Button".

If an incoming call is being forwarded from another user or is being forwarded as part of a call pickup group, this is displayed in the popup call notification, however it is not displayed in the users call history. The calls just show as a missed call.

This is causing confusion for users as they see these forwarded/call group calls as missed calls and then try to return the call.

An additional column or a different 'Type' for these calls would resolve this issue.

Please make the contacts that show up in the calling tab to be synced with a persons outlook or global address book of sorts. It's annoying having to manage so many different contact books

As an avid gamer, I feel like we gamers are very good at collaboration.
I would like to have a voice channel much like to see a passive voice channel where your team members can join and passively talk to each other as they work Much like how discord or team speak works in addition to what already exist in teams. This also will break up the monotony of needing excessive Skype meetings. For people whom work in the department, but are Geographically separated, and cant getup from their desk to just ask a teammate a simple question.

Please create a setting a user has the ability to change that automatically blocks incoming calls or allows the user to even forward all calls to someone else when already in a call/meeting if applicable. It is very distracting to have my phone ringing while I'm in a call.

It would be nice to be able to assign more than one user number to a single user. Call qeues are not always a suited solution. E.g. if the user needs to dial out with different numbers.

When putting a PSTN call on hold in Teams the caller will hear music. But when you do a consultative transfer the caller gets total silence before he gets transferred. Please also add music here.

All of us who are starting to use teams are facing the same issue...there is no way to control the volume on the teams calls

From our perspective it is really instrumental for people to use Firefox and still join our calls. There are some clients of ours who only use Firefox and we cannot force them to go through hops to join calls (like installing Chrome or Teams just to talk to us once). Please add that support! Thank you very much in advance!

Video calling works great, but one feature I really wish Teams had in common with Skype for Business is the ability to hide my own video. It's pretty distracting and makes me feel a bit self-conscious, so I often end up turning it off... Skype has a little button in the top right of the user's own video that hides it. This would be really useful!
