N/A N/A sips persistent tls Enables or disables the use of Persistent
Transport Layer Security (TLS).
Persistent TLS sets up the connection to the
server once and re-uses that connection for
all calls from the phone. The setup
connection for Persistent TLS is established
during the registration of the phone. If the
phones are set to use Persistent TLS, and a
call is made from the phone, this call and all
subsequent calls use the same
authenticated connection. This significantly
reduces the delay time when placing a call.
Notes:
1.
There can be only one persistent
TLS connection created per phone.
2.
If you configure the phone to use
Persistent TLS, you must also
specify the
Trusted Certificate
file
to use. The Root and Intermediate
Certificates, Local Certificate, and
Private Key files are optional.
For more information, see Chapter 6, the
section,
“Transport Layer Security (TLS)” on
page 6-21 .
