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

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.

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.

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.

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.

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".

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

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.

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.

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.

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 you call someone using Teams as your Phone system, the caller ID on the receiving end only shows a phone number and location. It should be possible to tag the company name to the number for Caller ID purposes.

In the desktop app, at least, show the call history for calling queues of which the user is a member.

If the user is a member of multiple queues, make the list filterable or selectable by calling queue.

The history should also show which user/agent answered a call so the other members of the calling queue can tell what happened, including whether the call was transferred and to whom (but there should be some security around this detail so administrators can configure this for the necessary amount of privacy).

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!

When making a PSTN call from Teams for browser or teams for VDI(Web RTC), PSTN Ring back tone/Early Media is not played.

User can hear the ring back tone of teams, but user cannot hear the PSTN Ring back tone or Early Media.
also as, user can hear PSTN Ring Back tone or Early Media when user use Teams for desktop client or Mobile Apps(iOS/Android).
