SIPS
SIPS are SIP data encrypted using the TLS protocol. The network protocol sets up a communication session between two or more subscribers.
The provider encrypts external connections to prevent listening in. The processes used to set up and shut down a connection, and signalling, are all encrypted by SIPS.
Requirement for configuration
The phone's certificate must be known on the PBX.
