I have Ooma office, with the Freedom headset. The only way I could get the device to register was to go into the portal and enable Dect scan. 3 attempts and 2 reboots and success. Then I went an assigned it to my extension as an added device, again success, (though device ID isn’t obvious, last 6 digits of the SN). I made an inbound call to Ooma, and attempted to answer with the headset, but I get the message that the device isn’t assigned an extension. It is per the Office manager, but shows offline. I tried a number of “dummy” updates, but it remains offline, and it will not receive calls.
