Can anybody confirm whether the UC520 supports the ATA-186 as a registered phone?
The Data Sheet and other documents i have checked so far doesn't make any reference. All they say is that you can use cisco IP Phone 79XX and of course the phone CP52XX series... too.
Would appreciate any link that directs me to a Cisco official statement.
I need to plug an analog polycom conference phone and don't want to give up my expansion slot with an FXS card.
