Hi @Vincent Lobaccaro,

CP-8861-K9 will not work out of the box with Webex Calling. These are meant for CUCM environment. There are now two options:

1. Replace these with CP-8861-3PCC-K9 or

2. Convert CP-8861-K9 from Enterprise Firmware to Multiplatform firmware using below procedure:

Hi @Vincent Lobaccaro,

Make sure these phones are Multiplatform Firmware (MPP) models (3PCC-K9). It is mentioned on back of the phone.
