UDP 49190
Synopsis
- Microsoft Lync and Skype for Business clients/servers use UDP ports 49152–57500 for RTP/RTCP media; UDP 49190 commonly appears as one of these negotiated media ports during voice/video calls and conferences. In real deployments, Skype for Business 2015/2019 Front End servers and Windows clients frequently bind to and exchange audio/video on UDP 49190, which shows up in packet captures and firewall logs. IP phones certified for Skype for Business (e.g., Poly/Yealink running SfB firmware) also use this same media port range, so RTP on UDP 49190 is routinely observed in those environments.
