I purchase the Yealink W79p with 1 phone and I purchased 2 extra phones. I can get them registered to the base but cannot get them provisioned enough though I am following the instructions to the T. I reset the base and phones to their factory settings, the I followed the instructions for auto provisioning. They have also been updated with the latest firmware.
I am at a lose.
I even tried manually provisioning and at least that gave me a green status on one of my lines in the admin portal but the provision still failed on the phones.
