Transport
Specify the transport protocol
for transmitting the 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.
Default: UDP.
