Note:
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 but is 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.
