+ 0 Votes RE: Shoretel issue Blackhatter1 1 year ago I take it nobody else has had a similar issue? Another related one we've noticed in addition to this is that you can add an additional phone to ring when a certain extension is dialed. (We have some wireless Polycom Spectra8300 phones with our Shoretel system.) Unfortunately the AddOn/AddOff button is no longer working to turn on/off the extra phone from ringing. It did originally when we first set them up and now it does not (although the AddOn/AddOff softkey is not grayed out like the Speed Dial softkey).
