Technical Details

what runs on :2142

This assignment covers TDM-over-IP traffic on both TCP and UDP port 2142. The technique transports timeslot or circuit-emulation data in IP packets; UDP is generally preferred for real-time carriage because it avoids retransmission delay, while the exact encapsulation, synchronization, keepalive behavior, and any handshake are implementation- or profile-specific. It should not be assumed that every standards-based TDM pseudowire profile uses this port, since related deployments may use other encapsulations, signaling channels, or provider-specific ports.

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

network services averages 2.7 across 1,437 ports — this one sits 2.3 above.

udp is connectionless — source addresses are trivially spoofed and it is a reflection favourite

security overview

TDM-over-IP traffic is normally not encrypted by the service itself, so exposed links can disclose carried voice or data and may permit traffic injection, replay, or disruption if the implementation lacks authentication and integrity protection. Port 2142 should generally be restricted to known peer gateways or a provider transport network, with encryption or authenticated tunneling used when the underlying circuit is sensitive.

service: TDM over IP
transport: TCPUDP
encryption: cleartext
assignment: iana registered
risk: 5/10caution
category: Network Services
usage: TDM over IP (TDMoIP) encapsulates legacy T1, E1, or similar circuit traffic for transport across packet networks. Engineers typically encounter it in carrier, enterprise telephony, and industrial gateway equipment rather than ordinary hosts.
