I received a response from Poly this morning asking for the OBI number of the 1062. I responded and then they told me to look in expert. That said I had removed the sidecar, but reattached it. It immediately was functional. But I reconnected it no different than several prior attempts.
Did they push something to the phone? Unknown but it is shown as connected and the buttons work.
That said I believe a limitation is that a pause cannot be programmed say for a conference call (e.g. phone number, pause, participant code).
