Description The protocol that the Real-Time Transport Protocol (RTP) port on the IP
phone uses to send out SIP signaling packets.

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.

If the phone uses Persistent TLS, you MUST specify the Trusted
Certificates; the Root and Intermediate Certificates, the Local
