Hi,

Any option to retain or make sure  7937 and 7975 IP Phones works in CUCM cluster, where cucm version 12.5 and TLS 1.2 enabled. As per cisco compatibility matrix, it doesn't work.

Any options please suggest.

Recommended option will be to  replace the 7975 and 7937 with a replacement phone models.

Replacement models will be 88xx series  and it support 1.2.

As these models of phones do not support TLS 1.2 your options are these, either you set the allowed TLS version to be lower than 1.2 or you replace the phones to models that do support TLS 1.2.
