For your problem, you can upload your server certificate mannualy on phone WUI to solve this issue.
Please refer to the picture attach to upload the file.

Best Regards,

Hello Lucia,

I did upload the server certificate of CUCM to the phone in the Trusted Certificate section. The phone still sends the "support@yealink.com" signed certificate and CUCM rejects it.
Is there a way to make the phone use exactly the certificate I uploaded and not its own?

Thank you for your help!
