CONFIGURATION FILES

DESCRIPTION
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:
• There can be only one persistent TLS connection created per
phone.
• 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.
