SIP Intercom Configuration

Starting from BioStar Air v2.10, SIP intercom functionality is supported on the BioStation 3 (BS3). This enables two-way audio calls between the reader and administrators, as well as remote door unlocking.

Note: This feature requires a SIP server, which must be purchased and configured separately. Suprema does not provide SIP service.


About SIP

The Session Initiation Protocol (SIP) is a communication protocol widely used for initiating, maintaining, and terminating real-time voice and video calls over IP networks. In this case, SIP enables the BioStation 3 to act as an intercom endpoint, making and receiving calls through a compatible SIP service.


Receiving Calls

Incoming calls from the BioStation 3 can be received via:

  • BioStar Air Web – Receive calls directly in your web browser.
  • BioStar Air Mobile App (iOS / Android) – Receive calls on the go.


Remote Door Control

When answering a SIP call, doors can be opened using DTMF commands from:

  • A physical SIP phone
  • The BioStar Air Mobile App
  • The BioStar Air Web interface


Configuration Steps

Configuration is required in two places: device settings and administrator account settings.


1. Device Settings

  1. Go to Device Management in the BioStar Air Portal.
  2. Select your BioStation 3 from the device list.
  3. Enter the following SIP server details:
    • Server Address
    • Port
    • Login Credentials (username and password)


2. Account Settings

  1. Each administrator who needs to receive calls must log in to the BioStar Air Portal or Mobile App.
  2. In Account Settings, add the same SIP login information used in the device configuration.
  3. This allows calls from the BioStation 3 to be routed to their browser or app.
