    Troubleshooting
    Review full answer

    If you can't complete the One Talk Desktop app setup, please check the following:

    Maximum number of devices error

    One Talk Desktop app displays a "Too many active SPC_METOKENs" error when you reach the maximum of 5 devices using the One Talk Mobile or Desktop app for that specific One Talk phone number.

    If the maximum number of devices has been reached, you must de-authorize 1 or more devices using the One Talk Admin portal or the One Talk mobile app before adding a new device. Deleting the One Talk Mobile or Desktop app from your device does not de-authorize the device, even though the app can't be used unless set up again.

    Contact you administrator if you're having problems de-authorizing a device.
