Conference Call Signaling
UDP port 1167 is commonly associated with signaling traffic for telephony and conference calling solutions, particularly legacy or specialized systems. It enables the setup, management, and teardown of audio conference sessions across IP networks. The use of UDP facilitates low-latency communication ideal for real-time voice traffic, though it can introduce challenges related to reliability and security. This port is often utilized in enterprise conferencing setups or hardware appliances supporting VoIP-based conference call features..
Port 1167 over UDP is typically leveraged by conferencing systems for signaling and control message exchange during multi-party voice calls. These communications often manage session initiation, participant management, media negotiation, and termination. Because it relies on UDP, communication benefits from minimal overhead and reduced latency, making it suitable for real-time scenarios like voice communications.
While this is not an IANA officially assigned port, some proprietary or legacy telephony solutions have standardized on UDP 1167 for internal operations or within enterprise networks. Usage may vary across different vendors, but generally encompasses signaling traffic — this does not usually carry the voice payload itself, which tends to use dynamically negotiated RTP streams.
Integration with larger VoIP environments can see this port facilitated by PBX systems, conference bridges, or dedicated hardware appliances. The reliance on UDP requires additional mechanisms such as sequence numbering and retries in higher-layer protocols to compensate for potential packet loss or disordering.
