You have got to be kidding me. The fix says:
"By downloading the beta firmware file, you expressly agree that the use of the firmware i your own risk and discretion."
As far as I am concerned, the dir-825 is not even a router if it is not capable of forwarding packets for a fundamental protocol. For d-link to claim this thing is a router is at least false advertising - it is not capable of performing its advertised task. And d-link wants me to take the risk in patching the firmware to get it to work as advertised? Hello, FTC, you there? This is not a router. Keep your nose out of my sip packets and forward them like a router would.
I want my money back because of that disclaimer. Only after I do some more complaining elsewhere.
Once again. The dir-825 is NOT a router.
