The Fanvil X303-2 Wire is a SIP phone that receives both data and power over a single pair of wires from a Fanvil PN8 or PN24 switch, at distances up to 300 m. With a 2.4-inch color screen and 4 SIP lines, it suits hotels and older buildings moving to IP while keeping their existing telephone cabling.
====
The Fanvil X303-2 Wire tackles a problem common in older Saudi buildings: an aging analog PBX, a single pair of telephone wires running to every room, and no network cabling at all. This phone takes both data and power over that same pair from a Fanvil PN8 or PN24 switch, so you can move to IP phones with a color screen and 4 SIP lines without opening walls or pulling new cable.
How the Fanvil X303-2 Wire works
In the old PBX room, install a PN8 (8 ports) or PN24 (24 ports) switch and connect its RJ45 uplink to your network and IP PBX. Terminate the existing telephone pairs on the switch ports, and plug the other end into the 2-Wire port on each phone. The switch sends data and power together, over distances of up to 300 m on Cat5e, RVV 2x0.5 or HYV 2x0.5 cable. To bring an ordinary network device onto a 2-wire line, Fanvil also offers the PN1 converter with one 2-Wire port and one RJ45 port.

Why upgrade over two wires?
Running new network cable to every room in an operating hotel or school means drilling, closing rooms and a large bill. A 2-wire upgrade leaves the cabling in place and only swaps the equipment at each end. Fanvil notes that networks with 60 or more phones, or cable bundles of 100 pairs or more, need network grouping configured with its PLC tool for stable operation, so plan that with your installer before the rollout.
Where the X303-2 Wire fits in Saudi Arabia
- Older hotels and serviced apartments in Makkah and Madinah that want an IP PBX without taking rooms offline.
- Schools and government buildings wired for analog phones.
- Hospitals and residential compounds with long internal cable runs.
- Offices that inherited an analog PBX and want IP features such as transfer, conferencing and voicemail.
PBX compatibility
The phone registers like any SIP endpoint. Fanvil's official compatibility list names the X303-2 Wire as supported on Yeastar P-Series and Yeastar Cloud PBX. It is configured through its web interface and can be found on the network with Fanvil's Device Manager tool.
X303-2 Wire or X303P?
Both have the same 2.4-inch color screen, 4 SIP accounts and 3 line keys. The difference is the connection: the X303P needs an RJ45 network cable at every desk and takes power from a standard PoE switch, while the X303-2 Wire runs on an existing telephone pair and needs a PN8 or PN24 switch. Choose the X303P for new buildings with network cabling, and the X303-2 Wire when telephone wiring is all you have.
Frequently Asked Questions
Does the X303-2 Wire run on ordinary telephone wiring?
Yes. It runs on a single pair from a Fanvil PN8 or PN24 switch at up to 300 m over Cat5e, RVV 2x0.5 or HYV 2x0.5 cable.
Do I need a power adapter for the X303-2 Wire?
Not when it is connected to a PN8 or PN24, which powers it over the same pair. A 12V/1A adapter is optional and sold separately.
Which switch does the X303-2 Wire need?
Per Fanvil's guide, the phone's 2-Wire port connects to a PN8 (8-port) or PN24 (24-port) switch.
