Since firmware updates were released for Teams native phones in January, the calling options (including call forward) were moved to behind the Admin Only settings menu, which is undesirable because we put a password on those settings to stop people messing with them.

See https://answers.microsoft.com/en-us/msteams/forum/all/call-forwarding-has-disappeared-from-our-common/aaf4ad07-9e94-4fb5-bf7c-4597b3c5cce5

We have some use cases where users who sign in to phones in CAP and Meeting modes need to use call forward functionality. Rather than arbirarily putting those options behind the the Admin Only menu, this is a suggestion to make it a configurable option using the "CsTeamsIPPhonePolicy" set of commandlets.

IP Phones configured in Common Area Mode should support a speed dial or favourites list allowing specific contacts or groups to be dialled with a single button push rather than dialling a person or group's phone number.

Scenarios where this would be beneficial are a lobby phone, hallway phone or reception phone.

Ideally, modifications would be locked on the IP Phone to prevent unauthorised modifications, and access to the dial pad would also be optionally locked the same as with the search and call park features.

When a person is using the calling feature on Teams, you can see this state if you hover over the presence indicator (which is red). It would be handy if there was a presence indicator which showed them being actually on a call (while using teams calling/pbx). Something similar to the do not disturb, which is the red with a white line in it. Maybe a red dot with a small white phone icon or other dedicated status indicator

We would like to have the ability to downgrade the firmware version on IP Phones. If a newer version coming with a bug, we can immediately to downgrade the version to the old one to avoid outage until the latest version without bug is released.

When calls are forwarded to another external extension (i.e. mobile) the number that came up on the mobile is the user phone number and not the original number of the person calling who has been forwarded to the mobile. It would be great to retain the original caller so user knows who is calling.

This made the new back in 2020, announcing support in the first half of 2021.

I cannot find any information.

This is a must and can definitely onboard all those companies that have invested in hardware and offset the cost.

The Devices (IP phone) management in Teams (from Teams Admin center Devices menu) is just a mess. No way to know which device was already assigned to a "Configuration profiles".
it does not push the new settings to the device when the "Configuration profiles" changed.
some IP phones are never show up as an IP phones from "Devices".
Need to see the member of a "Configuration profiles".
It is the best to have powershell cmdlets to manage the device.
Such as "Get-CSteamsdevices, Set-CSteamsdevices, Set-CSTeamsDevicesProfiles, Grant-CSTeamsDevicesProfiles, get-csteamsDevicesProfilesmememer, set-csteamsDevicesProfilesmememer, Update-csteamsdevice, reboot -csteamsdevice, remove-csteamsdevice, remove-CSTeamsDevicesProfiles...
etc.

Currently there are only two available Time Formats in the IP Phones > Configuration Profiles.
The Time Formats are: DD\MM\YYYY & MM\DD\YYYY. We would like to have especially in APAC for YYYY\MM\DD & YYYY\DD\MM

I use Teams to make external audio calls. I would like an option to be able to export a log of the outgoing calls I made, or incoming calls received/missed. I'm currently in dispute with a supplier about how many times I've called it recently and how long I've been on hold.

I can drag the cursor over the screen and copy/paste or take a screenshot, but a csv export log of call, number, date, time, duration, etc. would be perfect.

Our VoIP phone system is up for renewal in 18months. I'd like to move the company across to Teams for telephony but without TAPI I cant do that. Any chance of creating a Teams TAPI extension our plugin so we can use with a variety of CRMs?

The Poly CCX received an update that causes handset and speaker phone to have issues and right now the only way to revert is touching every phone with a usb to downgrade to previous version of the software. The Teams admin portal should be able to give a choice of software so the software can be pushed out exactly like an upgrade.

Trying an automated tool like Instant Data Care OST to PST Converter Software can the one stop solution for your OST to PST migration.

As we implement TEAMS to our global organizations the TEAMS enabled phone options is lacking for manufacturing areas and common areas.

The Poly, Audiocodes and Yealink devices are great for general office spaces. But need a simpler phone for common area like guest phone in front lobby or ruggedized phone for manufacturing areas that does require a large touchscreen display.

Both features are crucial. They used to both be available on the Skype firmware.
Users should not have to wait for the device to timeout to lock itself. They should be able to tap to 'lock' i.e. when moving away from their desk.
There should be a symbol/ icon to indicate that the call forwarding feature has currently been turned ON. This is crucial in Service scenarios where a number of people (i.e. working different shifts) use the same phone, so they are aware it is currently ON and can then turn it OFF.

In order to pull a simple inventory report of user name, email,phone numbers,license type etc I had to spent couple of hours with support on case#26867893 and I would recommend you to make this report available in Teams Admin Console.
