Can I Upgrade Yealink’s Open SIP Phone to Microsoft Teams?
Q: Can I upgrade Yealink’s Open SIP Phones to use with Microsoft Teams? What about getting back to Open SIP from the Teams?
A: By default, the phone has a built-in Teams feature license, which allows the user to use Yealink phones with Teams features directly. Any Open SIP/VCS build upgrades to Teams build will be required to apply and import the license. Any Teams will not be allowed to downgrade to the Open SIP/VCS from this release. If Teams are under temporary license (for demo testing purpose) and want to get back to Open SIP/VCS please contact Yealink support team for technical support for a unlock license.
