I am late to this thread but I am trying to find out if a "migration license" is needed for my scenario. Client has Cisco 8841 phones that are running the latest multi-platform firmware. Client wants to try to use the phone with Microsoft Teams (only) - so the plan was to remove the device from the Cisco Webex Hub, add the MAC address to Teams, get a phone number, assign a Teams Phone and Calling plan to the user, assign the number to the user. All went well and then after a few reboots we see the purple Teams background on the phone, but we cannot sign in. There is a message over top of the sign in that says a migration license is required. So my question is - to use this device with Teams (and not Webex) - does Cisco require a license? If so, does anyone know what that license is called and how much it is? I have read quite a few links and watched videos, but nothing has been crystal clear as to what is needed or not.
