Source note · Webex Calling ICE media path optimization
Cisco states that UDP is its preferred transport protocol for Webex Calling media and recommends using only SRTP over UDP, and that TCP and TLS as transport protocols for media are not supported for Webex Calling in production environments because their connection-oriented nature affects media quality over network loss.
