UDP 2094
Synopsis
- UDP port 2094 is used by 3Com NBX IP telephony systems; it is registered by IANA as the nbx-au service.
- In practice, 3Com NBX PBXs (e.g., NBX 100, V3000, V5000) and NBX IP phones (e.g., 2102, 2106) require UDP 2094 (along with 2093 nbx-cc) open between handsets and the NBX call processor for phone services/management, as documented in vendor firewall guidelines.
