I've upgraded to FF 150 with digital voice. It's been 2 days since the install and the grandstream ht801 ATA is not registering, so the phone led is not turning on. A fault was opened but I see that this has been closed, I also received an SMS saying engineer had fixed the fault that was at 12:34. Nothing has changed. Have gone through all the advice that has been given on previous issues with this. Nothing is working. I don't believe that the ATA is factory resetting, have been able to login to the ATA admin page and says its been unable to download the xml config.
Anyone have any ideas how to resolve this, or could it be a faulty ATA?
