Frequently Asked Questions

6 FAQs
Yes. As a standard SIP endpoint, the R20BX5 can register directly to most SIP-based VoIP PBX systems (like 3CX, FreePBX, etc.). This allows incoming calls from the door station to ring on any SIP device registered to the PBX, including desk phones, DECT phones, or softphones on PCs and smartphones.
To answer calls remotely on a smartphone, you need a SIP PBX server that supports mobile app connectivity. The door phone registers to the PBX, and the PBX extends the call to the official mobile app (e.g., 3CX App). The R20BX5 itself does not have a standalone app.
The buttons are programmed via the device’s web configuration interface. You assign a unique SIP extension number (or URI) to each button, corresponding to the tenant’s indoor monitor, SIP phone, or extension on the PBX.
Yes. The two independent relay outputs can be configured to control two different electric lock mechanisms, a door and a gate, or one lock and one auxiliary device like a light. Each relay can be triggered by different RFID cards or via calls from specific tenants.
No, the R20BX5 is an outdoor master station unit. It is designed to connect to and call compatible devices. For a complete system, you will need to pair it with SIP indoor video monitors (like the Akuvox R21H), standard SIP phones, or use it in conjunction with a PBX and smartphone apps.
It supports the most common 125kHz frequency cards (EM4100 format). Please verify card compatibility with your existing system if you plan to integrate.
