This section describes Transport Layer Security (TLS) and certificate management.
27.1 SIP over TLS Overview
TLS is a cryptographic protocol which provides communication security over the transport
layer (TCP). Generally, the TLS protocol uses private and public keys for authentication.
The authentication is performed by the certification authority (CA). Full protocol
specification is updated in RFC 5246.
Note: You must obtain the relevant CA, Private and Certificate (Public Key)
files from your Certificate Authority (CA).

The Certificate Authority (CA) is a body that certifies the ownership of a public key by the
name subject of the certificate.
