The Ooma Telo setup app is intended to only perform very basic setup of the device. Once this setup has been completed, OomaSetup doesn’t offer much value.
One huge problem with OomaSetup is that it does not recognize the replacement LTE Adapter device that Ooma recently sent out (June 2022) to replace the old LTE Adapter, in order to move LTE connectivity from the old Sprint LTE network to the T-Mobile LTE network. While the new LTE Adapter does work, OomaSetup indicates that the LTE Adapter is disconnected. So it’s not useful at all now, because OomaSetup used to be able to check the LTE signal strength, and could be used to find an optimum location for the LTE Adapter.
Please update OomaSetup to recognize the new LTE Adapter.
