be able to turn down the level of incoming calls so it does not ring as loud in the headset. as well as being able to turn volume up & down while on a teams calls. chat alerts should have the same volume option not just mute or un mute

When transferring a call, you should first be presented with a user managed list of favorites like what is on the home screen (MP56). The process of typing in a name for every transfer is unnecessarily time consuming.

It would be great to hide some call queues from users so that they cannot be directly called. Currently if someone is transferred to a call queue it will appear in their chat history and will be able to call the call queue. for this case we don't want people to see the queue so they can skip the queue process.

Not all screems or sub screens rotate when Ms Teams is rotated on a Phone from portrait to landscape. For example the chats or participants screen does not rotate...it is only the main screen that rotates.

Teams can only call internal people but If it has External calling option like dial pad that will be on added advantage.

Currently the Teams IP Phones do not auto dial when you enter 4-digits of a contact number. This feature was available in Skype IP Phones.

when a call comes through to a business and another team member picks it up, the people who do not pick the phone up, have the call shown as a missed call when it should realistically say picked up by team member and their name

How do I add the contact information into teams from O365 so that instead of displaying the number of the person calling it displays the name as well as the number?

How do I do this on a company-wide scale?

As an Admin you should be able to disable the confirm accept call prompt for queue calls. Let me provide an example so that the request is clear:
Customer calls call queue
Call queue rings user
User answers the phone
Teams then ask the user to press one to accept the call.

That is the prompt that as a Teams Admin (Voice Admin), however, the rights get setup, you should be able to disable.

Automatically assign teams device policy to new teams devices.

Add the features from Skype for business that we left out

Won't be using Office 365 Calling until there's a choice of providers.

I'd like to see additional infos in the incoming call popup, like the Outlook contact info (like Company or personal notes i made for the contact).

In Skype there was a thing like SuperToast or others, that could do it i think.

Please let us configure the amount of info to show. Ad the time it will be visible too.
That would be great.

Can you make a simple function that allows you to merge phone calls in teams? Regularly I will be on call with a team mate & another one calls in. I have to hang up and call both back. Should be able to simply merge as many calls as needed. Should also be able to forward a "JOIN" invite while in a meeting.

Teams IP Phones do not have distinct PowerShell commands to manage them. They have to be "cobbled together" through other means.

The management in the Admin Center is present

I have outlined here what would be needed: https://github.com/MicrosoftDocs/office-docs-powershell/issues/7017

In Summary:
Get-TeamsIPPhone (querying all three below)
Get-TeamsCommonAreaPhone
Get-TeamsConferencePhone
Get-TeamsMeetingRoom
This would be analog to what we have in the Admin Center right now.

Thanks,
David

Currently, if you forward your Teams Phone (external VOIP calls) to voicemail, all of your internal Teams Audio calls (employee to employee with no telephone number) are also forwarded to voicemail. I would suggest handling them separately. Forward to voicemail for telephone VOIP calls, but use the presence / do not disturb to avoid internal audio calls. I get many cold calls from vendors each day and want to forward my telephone, but not my Teams audio from internal colleagues.
