The W70B is Yealink's entry-level DECT base station. A PoE-powered base that supports up to 10 SIP accounts and pairs with Yealink DECT handsets (W53H, W56H). It is sold as a base station only: no handset is included. For businesses that want cordless VOIP at a lower entry price than the W76P bundle, or that need to add a DECT base to an existing handset deployment, the W70B is the starting point.

Base station only -- no handset included. The W70B is the DECT base unit. You need at least one compatible Yealink handset (W53H or W56H) to make and receive calls. If you want a complete DECT system with base and handset bundled, see the Yealink W76P review instead.
Who is this phone for?
The W70B suits three specific use cases. First, businesses that already own compatible Yealink DECT handsets (W53H or W56H from a previous deployment) and need an additional base station -- the W70B lets you expand coverage or add more registered handsets without replacing existing hardware.
Second, businesses shopping for the lowest entry price on a Yealink DECT base who intend to purchase handsets separately. The W70B base costs less than the W76P bundle -- if W53H handsets are available cheaper through a different channel, buying base and handsets separately may produce a lower total cost.
Third, warehouse, hospitality, or retail environments that need extended DECT range -- RT30 repeaters extend coverage from a single W70B base for larger sites.
💡
Who should consider the W76P instead: The Yealink W76P bundle includes a W56H premium handset alongside the base, which has a larger screen and HD audio. For most office deployments where you are purchasing a complete DECT system, the W76P bundle is the cleaner option. See the W76P review for a full comparison.

Compatible handsets
The W70B works with the following Yealink DECT handsets:
W53H -- entry handset, 1.8" colour screen, standard call features. Lower cost per handset. Suitable for general staff positions.
W56H -- premium handset (included in the W76P bundle), 2.4" colour screen, HD audio (G.722), push-to-talk, louder speaker. Better audio and display at higher cost per handset.
Up to 10 handsets can be registered to a single W70B base. RT30 repeaters can extend coverage for larger sites.
Call quality on Australian NBN
DECT operates on its own 1.9GHz radio band, separate from Wi-Fi. DECT operates in Australia's 1880 to 1900 MHz band rather than the 2.4 GHz or 5 GHz Wi-Fi bands, avoiding direct contention with traffic on those Wi-Fi bands. -- warehouses, hospitality venues, and offices with many Wi-Fi devices benefit from this separation. DECT does not compete with 2.4GHz or 5GHz traffic.
G.722 HD audio is supported by the W70B, and Yealink also specifies the W53H as an HD-audio handset. On W56H, call quality is noticeably cleaner than traditional DECT systems.
Register the base to your SIP provider as a standard SIP device. Yealink RPS auto-provisioning handles the configuration if your provider supports it. Ensure SIP ALG is disabled on the router -- DECT base stations are equally affected by SIP ALG as wired phones.
Features
The W70B provides the core DECT infrastructure for a Yealink cordless system:
10 SIP accounts -- register up to 10 separate SIP accounts on the base. Assign different accounts to different handsets or groups.
20 simultaneous calls -- supports multiple active calls at the same time across registered handsets.
PoE powered -- the base is powered from an 802.3af Ethernet switch. No mains adapter needed at the base station, which simplifies mounting (can be wall-mounted near any Ethernet port).
RT30 repeater support -- extend coverage for large-site deployments. Used in warehouses, clinics, restaurants, and multi-floor offices.
G.722 HD audio -- supported with W56H handsets for clear call quality.
SRTP/TLS -- encrypted calls and signalling supported.
Yealink RPS auto-provisioning -- compatible with AU hosted PBX providers that support Yealink provisioning.
What works / What doesn't
Pros
PoE powered -- mounts cleanly near any Ethernet port without a power adapter
The W70B base station retails around $109 AUD from Australian ICT and communications retailers. Handsets are purchased separately -- the W53H is the entry handset and the W56H is the premium option. Pricing updates nightly on this page from StaticICE AU data.
For a complete DECT bundle, compare the total cost of W70B + handsets against the W76P system price before ordering.
The W70B is the right choice when you need a DECT base for an existing handset fleet, are expanding an existing Yealink DECT installation, or need to extend range with RT30 repeaters. As a starting point for a new single-system DECT deployment, compare the total price of W70B plus handsets against the W76P bundle -- the bundle is often comparable in cost and includes a premium W56H handset.
For a single-office DECT system with one base and one to four handsets, the W76P bundle is the cleaner starting point. The W70B makes more sense for volume handset deployments, multi-cell sites, or additions to an existing DECT fleet.
Frequently asked questions
The W70B sits in the DECT cordless category alongside the Yealink W76P. Our best SIP desk phone Australia roundup covers when a DECT base station system is the right choice over a wired handset, and compares the W70B and W76P for businesses where staff mobility is the primary requirement.
The W70B can register with a compatible SIP service or SIP PBX, which may be cloud-hosted or on premises. Our guide to the best VOIP phone system for small business in Australia identifies which Australian hosted PBX platforms support multi-handset DECT deployments and what a full cordless setup costs for a small team.
New to IP phones or setting up a Yealink W70B for the first time? Our new IP phone setup guide covers VOIP provider selection, SIP credential entry, Ethernet connection, auto-provisioning, and troubleshooting the "Not Registered" display -- everything you need before making your first call.
The W70B base also supports the Yealink CP935W wireless conference phone. If your deployment already runs a W70B, the CP935W registers to the same base without a separate SIP line. See our Yealink CP935W review for the full setup details and AU pricing.
The W56H DECT handset is one of the compatible handsets for the W70B base. If you need to expand an existing W70B deployment with additional cordless handsets, the W56H is the option to add. See our Yealink W56H review for specs and pairing instructions.
What handsets work with the Yealink W70B?
The W70B is compatible with the Yealink W53H (entry handset) and W56H (premium handset). Up to 10 handsets can be registered to a single base. The W56H is included in the W76P bundle; The W53H was discontinued by Yealink on 30 September 2022; any standalone availability is limited to residual distributor or retailer stock.
What is the difference between the Yealink W70B and W76P?
The W76P is a complete bundle: W70B base plus one W56H premium handset. The W70B is the base station only -- no handset included. If you need a complete DECT system, compare the total price of W70B plus handsets against the W76P bundle price. The W76P is typically the better value for a single-system purchase.
Can the Yealink W70B be used for multi-cell DECT coverage?
The W70B itself supports up to 10 handsets and 20 simultaneous calls on a single base. RT30 repeaters extend DECT range for larger sites such as warehouses, clinics, hospitality venues, and multi-floor office buildings.
Is the Yealink W70B compatible with Maxotel and other AU hosted PBX providers?
Yes. The W70B supports Yealink RPS auto-provisioning, compatible with AU hosted PBX providers including Maxotel. The base registers as a standard SIP device on your provider's platform.
Does the Yealink W70B require a power adapter?
No. The W70B is powered via PoE (802.3af) from any PoE-capable Ethernet switch. No mains adapter is needed at the base station, making wall-mounting near a patch panel straightforward. A power adapter is included as an alternative if PoE is not available.
