CA12CD and Cisco Cp-8851

I am attempting to use a CA12CD with new CP-8851s that were just installed. We do not need the PTT function, since this will just be to a phone. The CA12CD uses a 6 pin connector with 4 wires, where the CP8851 has a 4 pin connector with 4 wires. I can't find an adapter that Poly makes for this situation. Any ideas?

Hello @ted_langdon 


Welcome back the Poly community. 

As per our compatibility guide, CA12CD is not compatible with CISCO 8851 phone and will not work so I am afraid we do not have any official solution to recommend.
