Tip: Changes to the Default TLS Cipher Suites in UC Software 4.0.0
Changes have been made to the default TLS cipher suites in UC Software 4.0.0. If you created
customized TLS cipher suites in a previous release of the UC Software, your changes will be lost
unless you backup the configuration files.
Configurable TLS Cipher Suites

Secure Real-Time Transport Protocol

Secure Real-Time Transport Protocol (SRTP) provides a way of encrypting audio stream(s) to avoid
interception and eavesdropping on phone calls. As described in RFC 3711, both RTP and RTCP
signaling may be encrypted using an AES (advanced encryption standard) algorithm. The parameters
used to configure SRTP are shown in
Polycom, Inc.
