The gate is already built. The CAT6 is already pulled. The client wants the visitor to press one button, call reception, speak clearly, and release the door from the desk phone. That is the buyer moment for the Fanvil i23 / i23S SIP audio door phone — not a retail handset purchase, but an ELV and PABX requirement that has to match the cabling, PoE switch, SIP platform, and door-release wiring on site.

For Dubai villas, warehouse entrances in JAFZA or DIP, staff doors, service gates, and office receptions, the i23 is specified as a SIP audio door station. It sits at the entrance, registers as a SIP endpoint, calls an extension or ring group, and triggers a door lock or gate controller through relay wiring. The important word is requirement. If the site does not have the right network point, power, SIP account, and relay path ready, the door phone cannot be handed over cleanly.

Vector Digital Systems LLC supplies Fanvil project hardware from Dubai, operating since 2009, with staging, provisioning, and installation across the UAE. For i23 and i23S enquiries, we confirm the exact site readiness before quoting: quantity, SIP platform, PoE availability, entrance type, lock wiring, and whether RFID card access is part of the scope.

What the Fanvil i23 SIP audio door phone is

The Fanvil i23 / i23S is an audio SIP door phone for entrance communication and access control. It is not a desk phone, not an analogue intercom, and not a standalone Wi-Fi doorbell. It is a network device that connects by CAT5e or CAT6 cable to the site LAN, registers to a SIP PABX or SIP server, and places a call when a visitor presses the call button.

In a normal Dubai office installation, the i23 is created as an extension on the PABX. Pressing the call button rings reception, security, a guard phone, or a ring group. The person answering can speak to the visitor and send a DTMF code to release the door, where the door-release circuit has been wired correctly. For villa gates, the same idea applies: the i23 calls the indoor extension or guard phone, then triggers the gate controller through its relay output.

The model supports 2 SIP lines, 10/100 Ethernet, PoE 802.3af Class 3, 12V DC power as an alternative, RFID card access, relay door release, indoor switch input, IP65 weather protection, and IK10 impact resistance. Those numbers matter because site teams often ask for “one door phone” without checking the switch, lock type, cabling route, or SIP credentials. We check those points before dispatch.

The i23 / i23S is best treated as part of the full entrance system: network switch, PABX, receiving phone, relay wiring, lock power supply, exit button if required, and card access if required. Supplied alone, it is only the door station. Supplied against a proper site requirement, it becomes a working SIP entrance point.

2 SIP lines — what that means on a door phone

The i23 has 2 SIP lines. On a desk phone, buyers sometimes confuse SIP lines with the number of outside calls a company can make. On a door phone, the explanation is different but just as important. The 2 SIP lines mean the device can register SIP call identities and handle call appearances according to its door-phone role. It does not mean the door unit is a mini call centre.

In practice, one SIP extension is usually enough for the entrance. The i23 may be extension 301, “Main Gate,” “Warehouse Door,” or “Reception Entrance” on the PABX. When the visitor presses the button, the door phone calls extension 100, a reception ring group, or a guard desk phone. The PABX decides who rings, how long it rings, whether calls overflow, and whether calls can be answered remotely.

That is why the call plan must be confirmed before installation. For a Business Bay office, the call may ring reception first, then security after 20 seconds. For a JAFZA warehouse, the entrance may ring the warehouse supervisor and the guard post together. For a villa compound, the call may ring an indoor SIP phone. The i23 starts the call. The PABX call route decides where that call goes.

The real differentiator: it is a SIP device, not a loose intercom

The useful part of the i23 is that it becomes part of the telephone system. A visitor at the gate can call a normal SIP extension. Reception can answer from a desk phone. Security can answer from a guard phone. A PABX installer can route the call by time, department, or branch policy. This is different from a closed intercom pair where the door unit only talks to one matching indoor station.

For a PABX replacement project in Dubai, this matters. Many buildings still have old analogue entrance panels tied to a small analogue exchange. When the office moves to SIP, the entrance should not remain separate. The i23 allows the entrance to sit on the same call plan as the rest of the office. Reception does not need a second answering device on the desk. The door call appears like a normal extension call, labelled by the PABX.

For integrators, that also makes staging easier. Before dispatch, Vector Digital Systems can register the extension, apply the provisioning details, set the call destination, configure the DTMF door-release code, and test the call path where the customer provides the SIP details. On project quantities, this reduces site work to mounting, cabling verification, relay testing, and final call testing.

This is the reason we ask for exact information at quotation stage. “Need Fanvil i23” is not enough. We need to know whether the site has PoE, which SIP platform is used, which extension should ring, what lock or gate controller is installed, whether RFID cards are required, and whether the entrance is wall-mounted or flush-mounted.

Access control requirement — call, RFID, password, and indoor switch

The i23 is specified for more than visitor calling. It also supports access by RFID card, password, call control, and indoor switch input. For a small office, that may mean reception releases the door after speaking to the visitor. For a staff entrance, it may mean authorised staff use RFID cards. For a warehouse, the indoor push button lets staff exit without calling security.

RFID capacity is useful only when the card process is planned. The customer should confirm how many cards are needed, who maintains the card list, and whether the cards are managed one by one or loaded during setup. If RFID is not part of the project, the cleaner scope is call button plus relay door release. Fewer moving parts. Easier handover.

The door-release side must be wired by the access-control or ELV installer. The i23 provides the relay trigger. The electric lock, magnetic lock, strike lock, or gate controller normally has its own power and control wiring. We do not treat the door phone as the lock power supply. On a proper drawing, the i23 relay is shown as the dry contact or trigger path into the lock power circuit or access controller input.

Typical Dubai project use cases

Villa gate: one i23 at the gate, one CAT6 cable from the network switch, PoE from the comms cabinet, SIP call to the indoor phone or guard phone, relay trigger to the gate controller.

Office entrance: one i23 at the glass door or service entrance, SIP call to reception, DTMF code for door release, and optional exit button on the indoor side.

Warehouse door: one i23 at the loading-bay entrance, SIP call to supervisor or security, RFID for authorised staff if required, and relay wiring to the access controller.

Power and network truth for Fanvil i23 / i23S

The clean way to install the Fanvil i23 / i23S is one CAT5e or CAT6 cable from the network switch to the door-phone location, with PoE feeding the unit from the comms room. The model supports PoE 802.3af Class 3 on the WAN port. That means the ELV contractor does not need a local power socket beside the gate or entrance if the switch is PoE.

There is also a 12V DC / 1A power option. That matters on older sites where the network switch is not PoE, or where the door station is being added to an existing entrance after the fit-out is complete. For a new Dubai office, villa gate, or warehouse project, we normally specify PoE because it gives one cable, one UPS-backed switch, and less clutter at the entrance.

The Ethernet ports are 10/100BASE-TX RJ45, not Gigabit. For a door phone, that is normal. Voice traffic and access-control signalling do not need Gigabit. What matters more is a stable cable route, correct VLAN tagging if the site uses voice VLAN, and a fixed IP plan so the door unit is easy to find during future service visits.

Requirement details that usually get missed

Most i23 installation delays are not caused by the door phone. They are caused by missing site details. The PABX extension is not created. The PoE switch is in another cabinet. The lock cable goes to the access controller but not to the door phone location. The customer wants RFID access, but no card list is ready. These are small items, but they decide whether the handover takes one visit or three.

For a proper staging job, we need the SIP server address, extension number, username, password, SIP port, transport choice, ring destination, unlock code, unlock duration, and IP plan. If the site uses a voice VLAN, we need the VLAN ID. If the i23 will open a gate, we need to know whether the gate controller accepts a dry-contact trigger and where that trigger cable lands.

Platform compatibility in Dubai projects

The i23 / i23S works as a SIP endpoint. In Dubai projects, that normally means registering it to 3CX, Grandstream UCM, Yeastar, Asterisk, or a hosted SIP platform. For business voice, Etisalat and du SIP services are usually presented through the customer’s PABX, not directly as a visitor-door call plan. The door phone should be treated like an extension with a clear call route.

During staging, Vector Digital Systems registers the extension, sets the call button destination, enters the DTMF unlock code, applies the IP settings, and checks the call path where the customer provides access to the SIP server. For a single villa gate, that may be one door phone and one indoor extension. For a warehouse, it may be two entrances, a guard desk, and a supervisor ring group. For an office tower floor, it may be a reception phone plus after-hours call routing.

The receiving side can be a desk phone, reception phone, guard phone, softphone, or ring group, depending on the PABX design. The important part is that the door phone does not make those call-policy decisions by itself. The PABX decides what rings, when it rings, and where calls go if nobody answers.

Fanvil i23 requirement check — choose by site condition

Choose the i23 / i23S if the requirement is SIP audio calling, RFID access, relay door release, PoE power, and outdoor entrance use. Do not choose it as a standalone doorbell. It needs a SIP platform, a receiving extension, network cabling, and relay wiring to become a working entrance solution.

AED quotation includes the unit quantity, power method, mounting scope, relay requirement, and any add-on items needed for the site. For project quantities, we can quote multiple entrances under one engagement with staging before dispatch.

Frequently asked questions

Will the Fanvil i23 work with our 3CX / Grandstream UCM / Yeastar?

Yes. The i23 / i23S registers as a SIP endpoint on 3CX, Grandstream UCM, Yeastar, Asterisk, and hosted SIP platforms where the customer provides the SIP account details. We configure the extension, call destination, and door-release code during staging.

Does the Fanvil i23 come with a power adapter, or do I need PoE?

The i23 / i23S supports PoE 802.3af Class 3 and 12V DC / 1A power. PoE is preferred for clean entrance installation. If the site has no PoE switch, we quote the power adapter as an add-on in the same order.

What does 2 SIP lines actually mean — can I make 2 calls at once?

The 2 SIP lines are SIP call identities and call appearances for the door phone role. In most installations, one SIP extension is used for one entrance. The PABX controls ringing, overflow, and simultaneous call limits.

Can the Fanvil i23 open a gate or electric lock?

Yes, where the relay output is wired correctly to the electric lock, gate controller, or access controller input. The lock normally needs its own power supply. We configure the DTMF unlock code and relay duration during setup.

Does the Fanvil i23 support RFID cards?

Yes. The i23 / i23S supports RFID access, with capacity for up to 500 RFID cards. For project setup, share the required card count and access method before staging.

Does Vector Digital Systems configure the Fanvil i23 before delivery?

Yes. Staging includes SIP extension registration, IP settings, call button destination, DTMF unlock code, relay timing, and test calls where SIP details are provided before dispatch.

Is VoIP legal in the UAE and will this work with Etisalat or du?

Business VoIP over licensed services is used in the UAE under TRA regulation. For door-phone projects, the i23 normally registers to the customer’s PABX, while Etisalat or du SIP trunking is handled by that PABX for outside calling.

Is the Fanvil i23 covered under Fanvil warranty in the UAE?

Warranty handling is managed through Vector Digital Systems from Dubai for supplied units, subject to Fanvil warranty terms, site condition, and availability status. Outdoor installation must follow proper cabling, power, and mounting practice.
