Technical Details

what runs on :4307

Port 4307 is the IANA-assigned TrueConf service endpoint over both TCP and UDP. It is used for TrueConf's proprietary client-to-server communications rather than a general-purpose protocol such as HTTP; the precise division of signaling and media traffic can vary by product version and configuration, and media may also use separate configured UDP ports. Do not infer that all conferencing traffic uses only 4307.

worth attention. how exposed you are depends on configuration — don't leave it reachable from the internet without a reason.

security overview

An exposed listener can reveal a TrueConf conferencing service and gives remote clients a point of contact for authentication and connection attempts. Conference services may carry sensitive audio, video, and organizational information: expose the port only where remote clients require it, enforce authentication, and keep the server current. TrueConf traffic is normally encrypted in supported deployments, but encryption does not make an unnecessary public listener safe.
