# WHATPORT(1071)

## NAME

port 1071 — BSQUARE-VOIP — Registered by BSQUARE for a VoIP product; no public protocol details and effectively no modern sightings.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

IANA lists 1071 as `bsquare-voip`, "BSQUARE-VOIP", registered by BSQUARE Corporation, a company known for Windows CE and embedded-device software. The VoIP product behind the registration was never publicly specified, and no current documentation for it exists. Nmap carries the name with no description. Modern VoIP you actually meet uses SIP on 5060/5061 and RTP in the high ephemeral range, not this port, so a listener on 1071 today is almost certainly something unrelated.

## EXPOSURE

**Expose with care.** Unknown service. Fingerprint it; if it is genuinely a signalling or media service, unencrypted VoIP control belongs on a trusted network only.

## CHECK

```sh
nmap -Pn -sV -p 1071 TARGET
```
