Enables or disables the use of Persistent Transport Layer Security

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.

• There can be only one persistent TLS connection created per

• 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.
