Cisco IP Phone encryption

Hi there,

I want to know if the communication encryption is enabled without installing an LSC certificate.

On the phone i can see : security mode : encripted , but the LSC is not installed.

Thank you in advance

Cisco IP Phone encryption

Hi Youssef,

As per the CUCM Security guide

Locally significant certificate (LSC)—This  certificate type installs on supported phones after you perform the  necessary tasks that are associated with the Cisco Certificate Authority  Proxy Function (CAPF). The LSC secures the connection between Cisco  Unified Communications Manager and the phone after you configure the  device security mode for authentication or encryption.
