Configuring TLS Certificates

The TLS Contexts table lets you configure X.509 certificates which are used for secure management of the device, secure SIP transactions, and other security applications.

●

The device is shipped with an active, default TLS setup (TLS Context ID 0, named "default"). Therefore, configure certificates only if required.

●

Since X.509 certificates have an expiration date and time, you must configure the device to use Network Time Protocol (NTP) to obtain the current date and time from an NTP server. Without the correct date and time, client certificates cannot work. To configure NTP, see Configuring Automatic Date and Time using SNTP.

●

Only Base64 (PEM) encoded X.509 certificates can be loaded to the device.

●

Modifying TLS Contexts doesn't require a device restart and therefore is not service affecting.
