Yealink endeavors to maintain a built-in list of most common used CA Certificates. Due to
memory constraints, we cannot ensure a complete set of certificates. If you are using a certificate
from a commercial Certificate Authority not in the list above, you can send a request to your
local distributor. At this point, you can upload your particular CA certificate into your phone. For
more information on uploading custom CA certificate, refer to Transport Layer Security (TLS) on
