Server Certificate
: When clients request a TLS connection with the system, the system
sends the server certificate to the clients for authentication. The system has two types of
built-in server certificates: a unique server certificate and a generic server certificate. You
can only upload one server certificate to the system. The old server certificate will be
overridden by the new one. The format of the server certificate files must be *.pem and
*.cer.
-
A unique server certificate
: It is installed by default and is unique to a system
(based on the MAC address) and issued by the Yealink Certificate Authority (CA).
-
A generic server certificate
: It is installed by default and is issued by the Yealink
Certificate Authority (CA). Only if no unique certificate exists, the system may send a
generic certificate for authentication.
The system can authenticate the server certificate based on the trusted certificates list. The
trusted certificates list and the server certificates list contain the default and custom certificates.
You can specify the type of certificates the system accepts: default certificates, custom
certificates, or all certificates.
Common Name Validation feature enables the system to mandatorily validate the common
name of the certificate sent by the connecting server.
And Security verification rules are
compliant with RFC 2818.
TLS parameters on the system are described below:
Parameter Description Configuration Method
Transport
Configures the type of transport protocol.
You can configure it for the
Zoom/Pexip/BlueJeans/Mind/Custom
platform, or SIP account separately.

UDP
—provides best-effort transport
via UDP for the SIP signaling.

TCP
—provides reliable transport via
TCP for SIP signaling.

TLS
—provides secure communication
for SIP signaling.

DNS-NAPTR
—performs the DNS
NAPTR and SRV queries for the service
type and port if no server port is
given.
Default:
For Zoom/Pexip/BlueJeans/Mind/Custom
platform, the default value is TCP.
For SIP account, the default value is UDP.
