Best DECT Cordless Phones for Office Australia (2026)

For most Australian businesses needing cordless phones, the Yealink W76P is the top pick. It supports up to 10 handsets per base station; coverage depends on the premises, and auto-provisioning compatibility varies by cloud phone provider. Below: how it compares against other DECT options, and which scenarios call for a different choice.

Top DECT Cordless Phone Picks for Business

Veterinary clinics are one of the most demanding DECT environments, staff move between reception, consult rooms, treatment areas, and kennels, often while unable to hold a handset. See our full guide to VOIP phone systems for vet clinics in Australia for area-by-area hardware recommendations and multi-cell DECT deployment guidance.

For businesses that need a full multi-handset DECT deployment, including multi-cell coverage across larger or multi-room premises, the Yealink W76P is the strongest current option available in Australia. It supports up to 10 SIP accounts and up to 20 simultaneous calls, with the option to add repeater units for extended range. See our full review for Australian pricing and configuration guidance.

What DECT Cordless Phones Actually Cost in Australia

IP DECT systems for business are sold as a handset-plus-base-station combination. The base station connects to your network and registers with your cloud phone system or on-premise phone system. Additional handsets pair to the same base. Current Australian advertised prices for mainstream one-handset Yealink IP DECT kits are approximately $189-$239 AUD, although prices and stock vary by model and reseller. Additional handsets are sold separately, and pricing varies by model and reseller; check live Australian pricing for the exact handset. Yealink's W80 multicell system uses a W80DM DECT Manager with W80B base stations. Grandstream's DP755 is a single base; Grandstream documents the DP760 repeater for extending its DECT coverage.Consumer DECT phones (Panasonic, Uniden, Oricom sold at JB Hi-Fi and Officeworks) typically run $80-250 AUD for a base plus two to four handsets. These connect to an analog phone port, either the green port on your ISP modem or an ATA adapter, not to a SIP-based phone system. They are cheap but they are not business VOIP phones and do not register with a cloud phone system. The distinction matters enormously, which is why this guide covers both the hardware decision and the underlying service decision.

What Is a DECT Phone and Why Do Businesses Use Them?

DECT (Digital Enhanced Cordless Telecommunications) is a widely used cordless-phone radio standard, including in Australia and Europe. It operates in the 1.9 GHz frequency band in Australia, which keeps it clear of Wi-Fi (2.4 GHz and 5 GHz) and reduces interference in busy office environments. DECT uses digital encryption between the handset and base station, providing better security and audio quality than older analog cordless standards.Businesses use DECT phones where staff need to move around while on a call: warehouse floors, retail spaces, medical practices where clinicians move between rooms, workshops, and small offices where a fixed desk phone does not suit every role. An IP DECT system connected to a compatible PBX can provide portable access to supported features such as hold, transfer, call waiting and voicemail.

IP DECT vs Analog DECT: The Decision That Actually Matters

This is the most important technical distinction for any business buyer, and it is the one most often missed. The two types of DECT system connect to your phone service in completely different ways and have fundamentally different capabilities.

Analog DECT (Consumer-Grade): What It Is and What It Cannot Do

Consumer DECT phones connect to a standard analog telephone line via an RJ11 connector. In the context of modern Australian offices, that RJ11 line comes from one of two sources: the green phone port on your ISP-supplied modem (an ATA adapter built into the modem firmware) or a standalone ATA device connected to your router. Either way, the phone connects to a traditional phone line signal. It does not speak SIP. It cannot register with a cloud phone system. An analog DECT phone does not itself register via SIP, but when connected through a compatible SIP ATA it can operate as an analog endpoint on an IP PBX; available PBX features depend on the ATA, service and PBX configuration.

IP DECT (Business-Grade): How It Actually Works

IP DECT phones connect their base station to your office network via an Ethernet (RJ45) cable. The base station registers directly with your cloud phone system or on-premise phone system as a SIP endpoint, exactly the same as a wired SIP desk phone. Handsets then pair wirelessly to the base station using the DECT radio standard. The result is a cordless phone that has all the features of your business phone system: extensions, ring groups, hold, transfer, call recording, voicemail-to-email, and so on.IP DECT base stations are configured the same way as any SIP desk phone: you enter SIP account credentials (from your cloud phone system company) into the base station's web interface, or use auto-provisioning if your provider supports it. Yealink and Grandstream provide automated-provisioning mechanisms, but support for each DECT base model varies by Australian cloud-phone provider and must be confirmed with that provider.

Base Station Requirements: What You Need Before Buying Handsets

Every IP DECT handset requires a compatible DECT base station on your network. Handsets do not connect directly to your router or phone system, they pair to the base station, and the base station talks to your VOIP system. This means for every set of handsets you deploy, you need at least one compatible base station on your LAN.Base station capacity varies by model. The Yealink W70B supports up to ten registered DECT handsets or headsets, ten SIP accounts and twenty simultaneous calls. The Grandstream DP752 supports five handsets and five concurrent calls. The Grandstream DP755 supports ten registered handsets and up to sixteen simultaneous calls across up to eight active handsets, limited to two calls per handset. For larger deployments, Yealink's W80B multi-cell DECT Manager system allows multiple base stations to be managed together with handset roaming across the coverage area.

DECT Range: What the Specs Mean in Practice

DECT manufacturers typically quote outdoor open-area range of up to 300 metres. Indoor range through walls and floors is always significantly lower, Manufacturers generally specify up to 50 metres indoors under ideal conditions. Actual indoor range depends on walls, floors, interference and base placement, so larger or complex premises require a site survey or coverage test. The DECT 6.0 standard (used in North America) and the European/Australian DECT standard use different frequencies but both deliver similar real-world indoor ranges.For multi-storey buildings or large floor plates, a multi-cell DECT deployment (multiple base stations configured to work together) is the correct solution. Yealink's W80B system and similar enterprise DECT solutions allow seamless handset roaming between base stations, so a user walking from one end of a warehouse to the other stays on the call without dropping.

Battery Life: What to Expect

Business-grade IP DECT handsets typically offer 15-30 hours of talk time and 200-400 hours of standby. The Yealink W78H claims up to 21 hours talk time, while the W73H claims up to 35 hours, which means a handset could, in theory, be in active use all day without recharging. Actual time between charges depends on call volume, signal conditions, settings, battery age and whether the handset is returned to its charging cradle.The Grandstream DP722 offers up to 20 hours talk time and 250 hours standby; the DP730 offers up to 40 hours talk time and 500 hours standby; both are more than adequate for most business use. The difference in battery life between Yealink and Grandstream DECT handsets is unlikely to be a deciding factor for most buyers. What matters more is whether the handset supports the DECT base station you are deploying and whether it integrates with your cloud phone system's provisioning system.

Multi-Handset Pairing: How Many Can You Connect?

Each DECT base station supports a fixed maximum number of registered handsets and simultaneous calls. These two numbers are different and both matter. You might have five registered handsets but the base station only supports four simultaneous calls, meaning if all five users try to call at once, one call will fail. Match your base station capacity to your actual simultaneous call volume, not just your headset count.For a small business with five staff where two or three might be on calls simultaneously, a single Yealink W70B base station with W73H or W78H handsets is sufficient. A single W70B is rated for up to 20 simultaneous calls overall, so five staff making one call each do not exceed its stated base capacity. Check SIP-account, per-handset and provider limits before selecting a larger system.

Yealink DECT Range: W73H and W78H

Yealink's current DECT range includes the W73H and W78H handsets for the W70B base station. The current mainstream handsets are the W73H and W78H, both designed to pair with the W70B base station.The Yealink W73H is the standard entry model: 1.8-inch colour screen, up to 35 hours talk time and up to 400 hours standby under Yealink's current specifications. It also offers a contact list of up to 1000 entries and full SIP feature support including hold, transfer, conference, and voicemail. Priced around $120-160 AUD per handset (check current pricing), it is the default recommendation for a small team needing one or two mobile handsets on their cloud phone system system.The Yealink W78H adds Bluetooth connectivity (allowing you to pair a wireless headset to the DECT handset) and a slightly larger 2.4 inch display with enhanced resolution. It targets users who want to use a Bluetooth earpiece while mobile. Priced approximately $190-225 AUD per handset. For most offices, the W73H is adequate; the W78H makes sense for staff who frequently use a headset while handling calls on the move.The W70B base station (required for both) connects via Ethernet, supports PoE, and can handle up to ten registered handsets and twenty simultaneous calls. It registers with your cloud phone system exactly like a SIP desk phone. Yealink auto-provisioning is supported by major Australian cloud phone system companies including Maxotel.

Grandstream DP Series: DP722 and DP730

Grandstream's DP series offers a cost-effective IP DECT alternative with strong feature parity against Yealink at a slightly lower price point. The DP722 is the entry handset (1.8 inch screen, 20 hours talk time, basic SIP feature set) pairing with the DP752 base station. The DP730 is the mid-range handset with a larger 2.4 inch colour screen and up to 40 hours talk time.The DP752 base station supports five registered handsets and four simultaneous calls, with PoE support. For larger deployments, the DP755 extends this to ten registered handsets and ten simultaneous calls on a single base, a meaningful difference if you have five or more staff who might call concurrently. Grandstream DECT is supported by major Australian cloud phone system companies via SIP configuration, though auto-provisioning support varies by provider. Check with your provider before purchasing.

Snom and Poly DECT Options

Snom is a German manufacturer with a strong reputation in the European market, increasingly available through Australian distributors. The Snom M-series (M65 handset, M900 base) targets the business market with emphasis on audio quality and build durability. A single-cell M900 can register up to 30 users and supports up to 10 narrowband or 5 wideband calls; in multicell operation, each base supports up to 8 narrowband or 4 wideband calls. Snom DECT pricing is marginally higher than Yealink and Grandstream equivalents but offers a robust alternative if preferred by your provider or IT team.Poly produces DECT headset systems such as the CS540, while its Voyager ranges are primarily Bluetooth headsets. rather than full DECT phone systems. Depending on the model, these wireless headsets connect to a desk phone, a PC, or multiple device types and allow movement within their rated range. They are not IP DECT systems, they do not register with a cloud phone system independently, but they are a legitimate use case for staff who want wireless freedom at a single workstation. If you need a standalone DECT handset that replaces a desk phone, look at Yealink or Grandstream instead.

What Most Businesses Get Wrong When Buying DECT Phones

Avoiding three common mistakes can help Australian SMBs make better-informed DECT purchasing decisions.

Mistake 1: Buying DECT Handsets Without a Compatible Phone System in Place

IP DECT handsets are handsets. They are the last step, not the first. A Yealink W78H sitting in a box without a SIP account to register to is useless. Before you order a single handset, you need: a cloud phone system company (who gives you SIP credentials and supports Yealink or Grandstream provisioning), a phone system plan, and ideally a test desk phone working on your service. Then you add DECT handsets. Buying handsets first and figuring out the service second almost always results in compatibility problems, configuration friction, or discovering that your ISP's bundled VOIP service does not support SIP registration at all.See our guide to choosing a VOIP phone system for small business and use the Phone System Sizing Wizard to confirm what you need before buying hardware.

Mistake 2: Confusing the ISP ATA Port With a VOIP-Capable Port

The green phone port on your NBN modem is an analog telephone adapter (ATA) port. It converts your ISP's cloud phone system service into an analog signal for a standard telephone. It looks like a phone port. It acts like a phone port. But if you plug a DECT base station's Ethernet cable into your router and try to register it with the service behind that green port, it will not work. Those are two completely different systems.This is the single biggest source of confusion for DECT buyers in Australia. ISP policy varies: some providers lock SIP credentials to supplied equipment, while others, including Aussie Broadband, provide credentials and BYO VoIP settings. Whether an ISP supplies usable SIP credentials varies by provider; confirm its BYO VoIP-device policy before purchasing an IP DECT system. You need a compatible SIP service that supplies usable credentials. This may be a business VoIP provider or an ISP voice service that permits BYO SIP devices; advanced PBX features require a suitably capable service.

Mistake 3: Undersizing Base Station Capacity

A base station that supports five registered handsets but only four simultaneous calls cannot support all five staff on calls at once; the additional call may fail or be rejected. This is rare but predictable in a busy service environment, reception desk, or a medical practice where multiple clinicians take calls simultaneously. Before purchasing, calculate your peak simultaneous call requirement, not just your headset count, and choose a base station with adequate capacity, or deploy two base stations if needed.

Australian Considerations for DECT Deployment

NBN and VOIP Call Quality

DECT phones on an IP DECT system are only as good as the underlying VOIP call quality. If your NBN connection has high jitter or packet loss, call quality will suffer on DECT handsets exactly as it would on a wired SIP desk phone. Before deploying IP DECT, confirm your internet connection meets the requirements for your expected call volume. As a baseline, each simultaneous VOIP call requires approximately 100 Kbps upload and download bandwidth using the G.711 codec. Four simultaneous calls need roughly 400 Kbps dedicated bandwidth, easily achievable on most NBN plans, but worth confirming.Use the VOIP Cost Calculator to check bandwidth requirements for your team size, and review our VOIP call quality guide for NBN-specific optimisation steps including SIP ALG disabling and QoS configuration.

PSTN Shutdown and Analog DECT

Legacy copper disconnection was progressive by area and began well before 2022; most mandatory disconnections in the NBN fixed-line footprint were complete by June 2023, with exceptions including Fixed Wireless and Sky Muster areas and some special or business services. In affected fixed-line areas, legacy copper services were generally disconnected or migrated; Fixed Wireless, Sky Muster and certain special or business services are exceptions, and the replacement voice arrangement depends on the provider. Confirm with your provider which voice service is active and which PBX, multi-call and routing features it supports.

Number Porting and DECT Deployment

When switching from an ISP voice service to a dedicated business phone company, you will likely want to port your existing number. Australian number porting generally takes 8-15 business days for standard geographic numbers under ACMA's Local Number Portability Code, and 1300 or 1800 numbers follow the separate Inbound Number Portability process. During the porting window, your existing number stays active on the old service. Plan your DECT deployment timeline to align with the port completion, configure and test your IP DECT system on a temporary number first, then the ported number takes over automatically once the port completes. See our PBX guide for more on how number porting works with hosted phone systems.

Power Outage Considerations

IP DECT base stations require power and a working internet connection to operate. Unlike a traditional PSTN phone, an IP DECT handset will not work during a power outage unless your network equipment (router, switch) is on an uninterruptible power supply (UPS). This is worth factoring into deployment planning for businesses where call availability during outages is critical, medical practices, emergency service adjacent businesses, and similar. For emergency-call backup, keep a charged mobile phone available. An analog phone on an ISP ATA works during an outage only if all required connection equipment, including the ATA or modem, has functioning backup power; limited FTTP battery-backup arrangements may also require a non-powered corded handset.

Choosing the Right Provider Before You Buy Handsets

The single most important step before purchasing any DECT hardware is confirming your cloud phone system company supports the model you are considering. Auto-provisioning, where the provider sends configuration to the phone automatically when it comes online, dramatically reduces setup friction and support calls. Auto-provisioning support for the W70B and its handsets varies by provider, firmware and purchase channel; confirm the exact base model with the provider before ordering. Grandstream is well supported but coverage varies by provider.Contact your provider before ordering hardware. Ask specifically: does your provisioning system support Yealink W70B (or your chosen base station model)? Can you pre-configure the handset for me? What SIP credentials do I need to enter manually if auto-provisioning is not available? The answers will shape your hardware choice more than any spec sheet.If you do not yet have a cloud phone system company, read our comparison of cloud phone system versus on-premise PBX and our overview of the best VOIP phone systems for Australian small business. Choosing the right service first will determine which handsets make sense.

Setting Up an IP DECT System: What the Process Looks Like

For a business deploying IP DECT handsets with a cloud phone system company, the setup process has five steps.Step 1: Confirm your cloud phone system company supports your chosen DECT base station model and can provide SIP credentials (or a provisioning URL if auto-provisioning is available).Step 2: Connect the DECT base station to your office network via Ethernet. Position it centrally for the coverage area you need. If using PoE, your switch powers the base station automatically. If not, connect the optional power adapter.Step 3: Register the base station with your cloud phone system. If your provider supports auto-provisioning (Yealink DECT is widely supported), this is as simple as entering the provisioning server URL into the base station's web interface. If configuring manually, enter the SIP server address, SIP username, and SIP password as provided by your cloud phone system company.Step 4: Pair handsets to the base station. Each handset is paired via the base station's registration mode. On the Yealink W70B, this involves pressing the FIND/INTERCOM button on the base to enter registration mode, then navigating to the registration menu on the handset. Step 5: Test calls, both inbound and outbound. Confirm call quality, hold and transfer functions, and that voicemail works correctly. Walk the coverage area to confirm range is adequate for your building.Setup time for a single-base, three-handset deployment varies with provisioning, firmware, network and provider requirements. Most cloud phone system companies offer guided setup support, Maxotel, for example, provides configuration assistance as part of their onboarding, so you do not need to have IT expertise to get a DECT system running.

When DECT Is the Right Choice (and When It Is Not)

DECT phones are the right choice when staff genuinely need to be mobile while on calls. Warehouses, retail floors, clinics, workshops, and small offices where the same person covers reception and walks to other rooms are all good use cases. The wireless range, battery life, and call quality of a modern IP DECT system is excellent for these environments.DECT phones are not the right choice when the user sits at a fixed desk all day. Depending on the models compared, a wired SIP desk phone from ranges such as the Yealink T-series or Grandstream GXP-series may offer a larger screen and more programmable buttons than a DECT handset. See our comparison of the best SIP desk phones for Australian business for desk phone recommendations.DECT phones are also not a substitute for a proper VOIP setup. The available line count, PBX features and scaling options are determined by the ISP voice service, ATA and PBX configuration, not by the analog DECT handset alone. If your business needs hold music, call queuing, after-hours routing, or multiple simultaneous calls, start with a cloud phone system company and then add IP DECT handsets. The phone comes last.

Your Next Steps

Before you buy any DECT hardware, work through this checklist:1. Confirm you have (or are getting) a cloud phone system or on-premise phone system with SIP credentials. If you are currently using the green port on your ISP modem, you need to address this first. Visit Get a Recommendation to discuss options.2. Confirm your cloud phone system company supports your chosen DECT base station model and can assist with provisioning or configuration.3. Calculate your peak simultaneous call requirement (not just your headset count) and choose a base station with adequate capacity.4. Check the coverage area you need. For a suitably sized open-plan office, one base station may be enough, but coverage should be confirmed with a site test. For a multi-storey building or large warehouse, plan a multi-cell deployment.5. Decide whether you need Bluetooth headset flexibility (Yealink W78H adds Bluetooth for headset pairing) or whether the standard W73H meets your needs.6. Use the Phone System Sizing Wizard to cross-check your seat count and call volume against the right system configuration before ordering anything.7. Order a base station and a single handset first. Test fully before ordering additional handsets.

DECT cordless phones are a common choice in hospitality for housekeeping and floor staff who move around the building. For the full context on phone system setup in hospitality environments, see VOIP for Hospitality Australia.

DECT handsets add a base station to the compatibility equation, not all business phone companies support DECT base station SIP registration directly. Our Phone Compatibility Checker covers major DECT models and assesses their compatibility with your VoIP platform.

Can I use a DECT phone with my ISP's NBN voice service?

Yes, but only an analog DECT phone connected to the analog port (green port) on your ISP modem. Consumer DECT phones (Panasonic, Uniden, Oricom) plug into that port via an RJ11 connector. Business IP DECT phones (Yealink W-series, Grandstream DP-series) connect via Ethernet to a SIP-based cloud phone system service, they cannot use the ISP's ATA port. You need a SIP service that supplies usable credentials and supports the device; this may be a business VoIP service or an ISP voice service that permits BYO SIP equipment.

How many handsets can I pair to one DECT base station?

It depends on the base station model. The Yealink W70B supports up to ten registered handsets and twenty simultaneous calls. The Grandstream DP752 supports up to five handsets and five concurrent calls. The Grandstream DP755 supports ten registered handsets and up to sixteen simultaneous calls across up to eight active handsets, limited to two calls per handset. For larger deployments, the Yealink W80 system provides true multicell roaming. Grandstream DP75x handsets can register to multiple bases, but base selection is manual; DP760 repeaters extend coverage within a compatible single-base system.

Do IP DECT phones work with all cloud phone system companies?

IP DECT compatibility depends on the provider's SIP implementation, credentials, codecs, security settings, firmware and device-support policy. In practice, the important question is whether your provider supports auto-provisioning for your chosen model. Yealink DECT systems have the broadest auto-provisioning support among Australian cloud phone system companies. Grandstream is well supported but check with your specific provider. If the provider supplies usable SIP credentials and supports the device's SIP settings, manual configuration may be possible through the base station's web interface.

What is the range of a business DECT phone?

Manufacturer specifications for IP DECT base stations typically quote up to 300 metres in open outdoor conditions. Manufacturers specify up to 50 metres indoors under ideal conditions for these systems. Actual indoor coverage depends on the building materials, layout, interference and base placement and should be tested on site. For coverage beyond a single floor or room, deploy multiple base stations. Yealink's W80 multicell system supports seamless roaming and handover. Grandstream DP75x handsets can register to multiple bases but switch between them manually; a compatible DP760 repeater can extend a base's coverage with seamless handover.

How long does the battery last on a business DECT handset?

The Yealink W73H is rated for up to 35 hours talk time and 400 hours standby; the W78H is rated for up to 21 hours talk time and 166 or 320 hours standby depending on hardware revision. Grandstream DP722 and DP730 offer up to 20 hours talk time and 250 hours standby. Actual time between charges depends on call volume, signal conditions, battery age and how often the handset is returned to its charging cradle. Placing handsets on the charging cradle when not in use, as most desk workers naturally do, effectively eliminates battery concerns for typical office usage patterns.

Do I need a separate phone line for each DECT handset?

No. In an IP DECT system, the base station registers the SIP accounts and maps them to selected handsets. An account may be shared across multiple handsets, or handsets may be assigned different accounts or extensions. Multiple handsets can receive the same incoming calls (ring all or ring in sequence), and the base station handles simultaneous call routing. You can also configure individual handsets with their own SIP accounts if needed, for example, if each person has their own extension. Your cloud phone system company configures this as part of your phone system setup.

Is a DECT phone better than a Wi-Fi softphone for mobile staff?

In office environments where Wi-Fi coverage or roaming is inconsistent, IP DECT may provide more reliable call quality than a Wi-Fi softphone on a mobile device. Wi-Fi softphones (apps on smartphones or tablets) are dependent on the quality and consistency of your Wi-Fi coverage, which is often patchy in warehouses and multi-room buildings. DECT uses a dedicated radio frequency separate from Wi-Fi, is designed specifically for voice, and provides predictable battery life and call quality. For staff who primarily work on mobile devices and make occasional calls, a softphone is adequate. For roles where call handling is a core activity, IP DECT is the more reliable option.
