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.
