Technical Details

what runs on :2095

NBX SER is a proprietary 3Com NBX telephony service registered for both TCP and UDP on port 2095. It carries NBX system or endpoint service traffic rather than a standardized SIP or HTTP exchange; deployments commonly use it with the related NBX directory service on port 2096. Exact framing and session behavior depend on the NBX software and appliance version, and the service is normally found only on legacy NBX systems.

security overview

This legacy telephony service should not be exposed directly to the Internet. It is not expected to provide modern encryption by default, and an exposed instance can disclose or affect PBX services depending on its version and configuration; restrict it to trusted voice-management and endpoint networks and investigate unexpected listeners.
