<div>&nbsp;That's what I had thought originally too, but apparently there is/was an issue with the 3.1.5gw and below firmware where it was possible for AC noise coming from the power supply to be falsely identified as a ring. Sipura has apparently just released 
3.1.7 to deal with this. </div>
<div>&nbsp;</div>
<div>&nbsp; I've never had this particular problem I think because I have the spa3k's here on an online UPS, but doing a bit more reading, Paul is certainly not alone with what he's been experiencing.<br><br>&nbsp;</div>
