TLS SUPPORT
The IP Phones support a transport protocol called
Transport Layer Security (TLS)
and
Persistent TLS
. TLS is a protocol that ensures communication privacy between the SIP phones
and the Internet. TLS ensures that no third party may eavesdrop or tamper with any message.
An Administrator can configure the following parameters for TLS Support.

FILES DESCRIPTION
N/A Transport
Protocol sip transport
protocol Specifies the protocol that the IP phone uses
to send out SIP messages. Default is UDP.
Notes:
1.
If you set the value of this parameter
to 4 (TLS), the phone checks to see
if the “
sips persistent tls
” is
enabled. If it is enabled, the phone
uses Persistent TLS on the
connection. If “
sips persistent tls
” is
disabled, then the phone uses TLS
on the connection. If TLS is used,
you must specify the Root and
Intermediate Certificates, the Local
Certificate, the Private Key, and the
Trusted Certificates.
2.
If the phone uses Persistent TLS,
you MUST specify the Trusted
Certificates; the Root and
Intermediate Certificates, the Local
Certificate, and the Private Key are
optional.

section,
“Transport Layer Security (TLS)” on
