VoIP Phone Accessories & Power Adapters

Why Might My VoIP Phone Need a Replacement Power Supply?

There are several reasons you may need a new IP phone power adapter.

Lost Power Adapter

Business phones may be moved between desks, offices or locations, and the original adapter can be misplaced during relocation.

Damaged Adapter

Power cables and adapters can become damaged through everyday use and may require replacement.

Moving From PoE to a Non-PoE Connection

A phone previously connected to a PoE-enabled network may need a local power adapter when moved to a network port or switch without PoE.

Setting Up an Additional IP Phone

An additional handset may require its own compatible power source depending on the phone and network configuration.

Testing and Configuration

IT technicians may use an external power supply while testing or configuring compatible phones away from the permanent PoE network.

Frequently Asked Questions

What accessories do VoIP phones need?

The accessories required depend on the phone and installation. A business IP phone may require a compatible power adapter if PoE is not being used. Other VoIP installations can use manufacturer-compatible accessories depending on the handset and business requirements.

Do Yealink phones come with a power adapter?

It depends on the phone model, package and supplier. Some Yealink IP phones are commonly deployed using PoE and may not include a power adapter. Check the individual product listing to confirm exactly what is included.

Do I need a power adapter if my Yealink phone supports PoE?

Not necessarily. If your Yealink phone supports PoE and is connected to compatible PoE network equipment, it can receive power through Ethernet without a separate mains adapter.

What is the Yealink SIPPWR5V2A-AU?

The SIPPWR5V2A-AU is an Australian-specification Yealink power adapter with a 5V DC, 2A output designed for selected compatible Yealink IP phones.

Which phones use the Yealink SIPPWR5V2A-AU?

The adapter supports selected Yealink models including phones from the T29, T38, T43, T46, T48, T52, T54, T56, T57, T58 and MP ranges. Check the full compatibility list on the product page before ordering.

Can I use a Yealink power adapter with any Yealink phone?

No. Different Yealink phone models can have different power requirements. Match the exact adapter model and electrical specifications to your specific handset.

Can I power a VoIP phone without PoE?

Yes, provided the phone supports an appropriate external power adapter. A compatible power supply can power the phone while the Ethernet connection provides network connectivity.

Is a VoIP phone power adapter the same as a normal power adapter?

It is still an AC-to-DC power supply, but that does not mean any generic adapter is suitable. The voltage, current, connector and polarity must meet the phone manufacturer’s requirements.

How do I know which power supply my IP phone needs?

Find the exact phone model and check the manufacturer’s specifications or compatibility information for the required power supply. If you are unsure, confirm compatibility before purchasing rather than selecting an adapter based only on its voltage.

Should I use PoE or a power adapter for my office phones?

PoE is often convenient for larger office deployments because compatible phones can receive data and power through Ethernet. A mains power adapter can be suitable for individual phones or locations where PoE infrastructure is unavailable. The right option depends on your network and phone models.
