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.

Description
N/A Transport Protocol sip transport protocol Specifies the protocol that the RTP port on the
IP phone uses to send out SIP signaling
packets. Default is USP.
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.
For more information, see Chapter 6, the
section, “Transport Layer Security (TLS)” on
page 6-26.
