Note:
The most common used CA Certificates are built in Yealink phones. Due to memory constraints,
we cannot ensure a complete set of certificates. If there is no the desired certificate in the above
list, contact your distributor for the desired one. After that, you can upload the certificate into your
phone. For more information on uploading custom CA certificate, refer to Transport Layer Security
(TLS).
