I have a SPA525G voip phone, I have a Motorola bluetooth headset that was working, but now it isn't (not sure why, but it works on my iPhone, and was working on both devices at the same time). I have tried to reset, setup etc. I have gotten as far as asking for a security code, which I didn't need before, but even if I had one, the keys do not work - none of them. So there is no way to even enter a code. The phone is out of any help from Cisco, so I would appreciate any suggestions anyone can give.
