SIP Intercom = old‑school intercom, but smarter. Remote open, real‑time talk – all over your existing network.

Say Goodbye to Proprietary Wiring, Embrace SIP

In the past, building intercom systems often relied on closed proprietary protocols and dedicated cabling. Difficult upgrades, complex cross‑building connectivity, and limited mobile access were common pain points.

Now, FARHD integrates SIP (Session Initiation Protocol) into intercom systems, merging your access control network with your everyday communication network. No need for extra dedicated wiring or learning complicated interfaces – use your familiar phone, PC, or front desk deskphone to answer visitor calls and control door access.

What Can SIP Intercom Do for You?

1. One‑Tap Call, Multiple Endpoints

When a visitor presses the call button on the door station, the call is routed to your preset devices:

• Mobile App (SIP softphone) – Wherever you are, as long as you have an internet connection, you can answer the doorbell like a normal phone call and see live video (if the door station supports video).
• PC (office scenario) – Employees can answer entrance calls via a SIP softphone on their computer, verify the visitor, and remotely unlock the door.
• Front desk / IP desk phone – Visitors can directly reach the reception desk, where staff can transfer the call or open the door – enhancing professionalism.

One door station can ring multiple endpoints simultaneously or sequentially, ensuring you never miss a call.

2. Remote Unlock + Real‑Time Talk – Security and Convenience Combined

• Remote unlock – After answering, press a DTMF code (e.g., “*”) on your phone or deskphone to release the door lock remotely. Receive packages, welcome guests, or grant temporary access – without leaving your seat.
• Real‑time two‑way talk – SIP supports high‑definition audio with minimal latency. For video‑enabled door stations, you can also see the visitor for visual verification.

3. Deploy Over Your Existing Network – Simple and Cost‑Effective

SIP intercom runs on standard IP networks (LAN/WAN). No need to lay dedicated intercom cables:

• The door station only needs a network connection (PoE or DC power) and registers with your existing IP PBX (e.g., Asterisk, 3CX, FreeSWITCH) or a cloud SIP service.
• No dedicated indoor monitors required – staff or residents can use SIP softphone apps on their own smartphones.
• For those who prefer a hardware terminal, FARHD also offers SIP indoor monitors with touchscreens and additional features.

Typical Use Cases: How SIP Intercom Empowers Different Projects

Scénario	Value of SIP Intercom
Office buildings / corporate campuses	A visitor calls the front desk; the receptionist transfers the call to the employee. The employee answers via desk phone or mobile app and remotely unlocks the door. No need to install dedicated intercom units at every desk.
Apartment buildings / residential communities	Residents answer door calls on their mobile phones – delivery people can enter without physical contact. Property managers centrally manage door stations via the backend, saving hardware costs.
Schools / dormitories	A visitor calls the dormitory management office; the staff verifies and remotely unlocks the door. In an emergency, one‑button calling to the security centre is available.
Hospitals / nursing homes	The nurse station IP phone answers calls from the ward entrance, preventing unauthorised access.
Parking lots / guard booths	A visitor presses the intercom button; the booth or control centre answers, verifies, and remotely raises the barrier.

Case Study: SIP Intercom Retrofit for a Multinational Tech Campus

Défi : The campus had an old intercom system that could not integrate with the company’s IP telephony system (3CX PBX). Visitors required manual verification by security, which was inefficient.

Solution : FARHD supplied SIP door stations that registered with the existing 3CX system. Visitors entered the employee’s extension on the door station, and the call was routed directly to the employee’s IP desk phone or mobile softphone. The employee answered, verified the visitor, and pressed “9” to unlock the door remotely. The front desk could monitor all entrance calls and take over in emergencies.

Résultats : Visitor waiting time reduced by 70%; security staffing reduced by 2 people per shift; employee satisfaction significantly improved.
