I was wondering if anyone else has ever had issues with this model phone? I recently purchased some refurbed 6416D+M phones to which I attached a headset and a brick for some new CS agents we recently added. For some weird reason, the handsets on two of them have gone "dead" but the headset still works. ? I've swapped phones and handsets and it seems to cure the problem for a short while until the handsets go dead again. What's going on here? Any ideas?
