Select the SIP transport protocol.
TCP (Transmission Control Protocol) is
the most reliable protocol and includes
error checking and delivery validation.
UDP (User Datagram Protocol) is
generally faster but SIP data may be
subject to network congestion.
TLS (Transport Layer Security)
transport requires security certificates to
establish a secure connection between
phone and server. Optional server
authentication is supported via user-
uploaded certificates. See Servicing >
Certificates on the "file" Module:
Imported File Settings on page 230.
