Transport
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 less prone
to latency, but SIP data may be subject to network
congestion.
TLS (Transport Layer Security)—the VSP725 supports
secured SIP signalling via TLS. Optional server
authentication is supported via user-uploaded
certificates. TLS certificates are uploaded using the
configuration file. See
“"file" Module: Imported File
Settings” on page 136
and consult your service
provider.
