Ensure compatibility with the Yealink T46U Version 2 running firmware version 87
A Yealink T46U is already running v87 firmware. RingCentral auto-provisioning targets v86 and pushes a downgrade as this results into a boot loop. It appears that the issue they are experiencing is a boot loop issue caused by firmware conflicts within their provisioning files forcing them to downgrade from V87 to V86. As confirmed from support, V87 is not yet supported
