TLS Transport Protocol
When using SIP account, SIP IP call, or logging in to Zoom, Pexip, BlueJeans or a custom third-party
platform, you can choose the TLS transport method for the SIP protocol to ensure the confidentiality of the
communication and the security of the information transmission.
About this task
