Certificate not trusted

[James_Yealink]

Hi JayPeg,

You can import a certificate through autoprovision in large deployment. Below are some related parameters

#Enable or disable the phone to only accept the certificates in the Trusted Certificates list;
#0-Disabled, 1-Enabled (default);
security.trust_certificates =

################################################################################​#######
## Trusted Certificates ##
################################################################################​#######
#Before using this parameter, you should store the desired certificate to the provisioning server.
trusted_certificates.url =

#trusted_certificates.delete = http://localhost/all,delete all the trusted certificates.
trusted_certificates.delete =

################################################################################​#######
## Server Certificates ##
################################################################################​#######
#Before using this parameter, you should store the desired certificate to the provisioning server.
server_certificates.url =

#server_certificates.delete = http://localhost/all, delete the server certificate.
server_certificates.delete =
