SIP Transport Protocol
Select the SIP Transport Protocol type from the drop-down list for using. There are two types of
Internet Protocol (IP) traffic. They are Transmission Control Protocol (TCP) and User Datagram
Protocol (UDP). To ensure proper connection, verify if both calling parties are using the same
transport protocol. By default, it is set to UDP.
TCP:
TCP is connection oriented. Once a
connection is established, data can be sent
bidirectional.
UDP:
UDP is a simpler, connectionless Internet
protocol. Multiple messages are sent as packets
in chunks using UDP.
TLS:
TLS is a cryptographic protocols designed
to
provide
security over
a computer network. SIP payloads will be
encrypted to prevent malicious or unwanted
modifications. NAT-traversal can be achieved by
TLS connections since SIP payloads will not be
altered by NAT-enabled routers
SIP Port
Change this value only if you use specific
settings in your network system. By default, the
SIP port is set to 5060.
