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 on page 223 .
