We have many 8845 phones with Plantronics headsets (CS540 mostly) with the proper EHS cable that before the upgrade to 12.5 would beep in the headset when a call came in. We were using sip8845_65.12-1-1SR1-4 and it worked fine. With 12.5, it no longer makes any sound at all. We can't find any setting to turn it back on so we're starting to downgrade phones with headsets. Does anyone have any ideas?
