I have several Crexendo branded Yealink T28P phones. They will take a configuration and work but they are stuck at firmware: 2.61.37.6
Is there an upgrade process for this? I have attempted install using TFTP and the web GUI and each time the phone says firmware upgrade but then it does not upgrade.
I have attempted to contact Crexendo but they have not responded.
