Please add a save dial number feature like on Skpye

When window is not maximized you should be able to double click the video call to maximize the screen

Many times when i get a call mobile teams app get ring but not desktop. So give an option to stop getting incoming calls on mobile

Similar to BTOE but no third party software to install.
The ability to choose and control the Teams phone device for inbound calls, outbound calls, and meetings from the desktop or mobile client based on logged in phone device.
Also allow switching the audio between devices and clients without having to transfer the call.

Make the Teams 'Calls' UI more like a cell phone.
My company has started using teams and almost everybody (well everyone I have called, and I do it too) hits the 'hang up' icon rather than the 'answer' icon. The correct icon to hit to answer the call is counter intuitive.

When using Teams as you office phone system it would be a great feature to be able to record the voice conversation.

Teams and Cisco should work together to integrate video calls from Cisco TelePresense unit into Teams.
Audio is possible with a usual PSTN dial-in but Video and Audio should work on SIP. Enviroments with 100 VC or more are not able to have a video call with a Teams member. Only additional software like Pexip are neccessary to build a bridge to both platforms.

Please add a ring-out option to the Teams mobile app when WiFi is unavailable (i.e., outgoing calls are dialed over cellular networks, not data networks).

This will prevent excessive data usage when in an area where WiFi is unavailable.

Like in Outlook email. difference between Delete and Archive. Archive will be searchable and locatable and delete will be permanently deleted.

Currently, when assigning a PSTN phone number through the Skype for Business admin center, there is no way to see who the number was previously assigned to or how recently it was in use. This information would help ensure that a recently unassigned number is not reassigned to a new user too soon after it was previously used to avoid misdirected calls.

It would also be helpful to be able to add a note to an unassigned PSTN number—for example, to indicate that a number is reserved for a particular user or department.

Would like to see the ability to search for a user and call from the results instead of:
Searching for a user, opening the chat window with them, opening the contact card by clicking on their picture, copying the PSTN line from the contact card, going back to the calls tab, pasting the phone number into the dial pad and then calling the user.

The current process is not efficient and a better work flow is needed!

Would like the ability to move the video streams while in a group Teams meeting sharing content. All the video streams appear below so all participants are looking down. If streams were on top (where most webcams located) then users would appear looking straight ahead.

Direct Routing in Teams works almost exactly the same as in Skype for Business on-premises except there is no support for trunk translation rules. This means that if you have to do any manipulation of numbers before sending to the PSTN, you have to do it at the PSTN gateway level. This probably isn't possible if you are using a service provider for Direct Routing.

It would be useful to have this feature added (maybe to the CsOnlineVoiceRoute cmdlet ) to give more flexibility when communicating with third party PSTN providers.

Is there any possibility to recover the recordings during the call which was not saved as the teams got closed unexpectedly?

Ability to forward a voicemail to another internal Teams user from the mobile and desktop apps. This is a valuable productivity feature.

For Office 365 phone system and teams to really start replacing PBX deployments it needs to add some missing features. One of the easy (hopefully) ones is to allow a user to have multiple lines associated with them such as region specific direct dial numbers. At present you can only associate one number.

When in a meeting, you can join from mobile as a companion device.

Need the ability to pull a regular voice call to mobile to keep going when you need to leave your computer
