We have bought some cisco 9841s to use on our on prem CUCM v15. I noticed in the documentation that this model of phone has a anti spam feature. I seem to be not able to add this feature to the phone. Is this feature only for Webex calling as when you boot the phone up you can select either webex or CUCM. Has any one been successful at adding the anti spam feature on these models to on prem.
