Small Business Line
eSBC Small Business Line VoIP gateway
Fixed interfaces, one job, entry-level price — for sites whose wiring is not going to change again.
Not every site needs a free module slot. A dentist’s practice with one ISDN line, a workshop with two analogue phones and a fax, a branch office with a door intercom — the interface list for those sites was settled when the building was wired and is not going to change. The Small Business Line is built for exactly that case: the configuration is fixed, the price reflects it, and nothing about the device invites a later rebuild.
What does not change is the software. The Small Business Line runs the same beroNet OS as the modular eSBC line, so the web interface, the dialplan syntax, the provisioning files and the beroCloud registration are identical. A technician who has configured a modular gateway does not need to learn a second product, and a fleet can mix both lines without a second management path.
Choose the model by what is actually on the wall. Two or four BRI for an ISDN line or an ISDN PBX, two or four FXS for analogue telephones, fax machines, alarm diallers or lift emergency phones, four FXO for an analogue provider line, and the hybrid with two BRI and two FXS for the mixed case that turns up most often in practice.
Features
- Six fixed configurations covering ISDN, analogue and the common BRI plus FXS mix
- Same beroNet OS and the same web interface as the modular line
- Registers with beroCloud for remote configuration, monitoring and firmware updates
- Compatible with any SIP PBX, on site or hosted
- Fanless aluminium housing, no moving parts
