If I'm following what you say correctly, the fact that you have added your OBi110 device to the OBiTALK Dashboard, it will override any changes made to the device, even after reset of any form. You should delete the device from the OBiTALK and then do a reset. Also, once you add the Device to the Dashboard, all changes to the configuration must be done there, as oppose to the local web interface, unless you disable the provisioning from the local web interface. Do some more reading on the basic, but I think that is what is happening.
