UDP 4060
Synopsis
- UDP port 4060 is commonly used by Unify (formerly Siemens) HFA/CorNet-IP, the proprietary signaling protocol for their IP telephony systems. Examples include Unify OpenStage and optiPoint desk phones registering and signaling with OpenScape Voice and OpenScape/HiPath 3000/4000 PBXs, which typically require UDP/TCP 4060 open on firewalls. Many Unify deployment guides explicitly cite 4060 for HFA signaling and keepalives.
