TLS Transport Protocol
When using SIP account, SIP IP call, or logging in to Zoom, Pexip, BlueJeans, EasyMeet or a custom third-
party platform, you can choose the TLS transport method for the SIP protocol to ensure the confidentiality
of the communication and the security of the information transmission.

Parameter Description Configuration Method
Transport
Specify the transport protocol
for SIP signaling.
The supported protocols are as
follows:
• UDP—it provides the best
transmission for SIP signaling.
• TCP—it provides a reliable
transmission for SIP signaling.
• TLS—it provides a safe
transmission for SIP signaling.
TLS is available only when the
device is registered on a SIP
server that supports TLS.
• DNS-NAPTR—the device
performs the DNS NAPTR
and SRV request to find the
service type and the port if
no server port is given.
Note:
• Yealink Cloud Platform and
StarLeaf Cloud platform
cannot be configured.
• The default value of the
Zoom/Pexip/BlueJeans/
Videxio/Custom Cloud
platform is TCP.
• The default value of EasyMeet
Cloud platform is TLS.
• The default value of the SIP
account is UDP.
• If you use TLS, you need to
upload the CA certificate to
the server for the devices.
