Yealink CP935W Review -- Australia 2026

Who is this phone for?

The CP935W is for businesses that need a conference phone in a meeting room without a fixed desk phone cable point -- or that want a conference phone that can be shared between multiple rooms. The cordless design means it can sit in the centre of a meeting table during a call and be stored when not in use, without dealing with cable management. Buy it for: meeting rooms without a patch point at the table, boardrooms where a cabled conference phone would require disruptive installation, businesses that move their conference phone between meeting spaces, and any environment where the cable management of a wired conference phone is a practical problem. The CP935W has built-in Wi-Fi and Bluetooth and can register directly to a SIP account over Wi-Fi -- no base station required. It can also run in DECT mode, pairing to a Yealink W70B DECT base station (or compatible W-series base) if you already have one deployed for other DECT handsets, sharing that base's SIP registration. If a wired conference phone is acceptable and cost is a factor, the Yealink CP925 is the cabled alternative at a lower price. The CP935W's premium is for the wireless freedom.

Specs at a glance

Setup -- what you need to get it working

The CP935W supports two setup modes. In Wi-Fi mode, it connects to your Wi-Fi network and registers a SIP account directly (from your VOIP provider, e.g. Maxotel) -- no base station involved. In DECT mode, it pairs to a Yealink W70B DECT base station (or compatible W-series base) and shares that base's SIP registration, useful if you already run Yealink DECT handsets (W56H, W76P) on a W70B. For Wi-Fi mode: join the phone to your Wi-Fi network via its touch screen settings, then enter your SIP account details directly on the device. For DECT mode: hold the pair button on the W70B base and the phone simultaneously until they register to each other, the same process as pairing a DECT handset. The entire setup takes a few minutes either way.

Audio quality -- microphone range and call performance

The CP935W's 6-metre 360-degree microphone pickup covers standard boardroom and meeting room configurations without needing to position participants close to the device. In practice, a conference table of 6-8 people around a standard table will be covered without anyone needing to lean in. For larger rooms or long tables, the pickup range is a limiting factor. In a 10-metre boardroom with participants at both ends of the table, the far end may sound distant. External microphone expansion units are not supported on the CP935W -- if coverage is a concern, a fixed conference phone system with expansion mics is a better choice for that environment. The built-in noise suppression reduces background noise in typical office environments -- HVAC, keyboard sounds, and ambient conversation. It does not eliminate noise from close sources (a fan directly beside the device, heavy traffic outside an open window) but handles normal office noise levels well. On Australian NBN, call quality through the W70B base is consistent with standard VOIP call quality. The DECT wireless link between the CP935W and W70B adds negligible latency and does not affect the quality of calls in normal indoor environments.

CP935W vs CP925 -- wired or wireless?

The CP925 is Yealink's wired conference phone at a lower price. It connects directly to the network via an Ethernet cable and is provisioned as a standalone SIP phone -- no separate base station required. Buy the CP925 when: your meeting room has an accessible patch point, cable management is not an issue, and you want a simpler setup without a DECT base. The CP925 is the lower-cost option for a single meeting room with a fixed location. Buy the CP935W when: you want to eliminate the cable, the meeting room does not have a table-accessible patch point, or you need to share the conference phone between multiple rooms. If you already have a W70B DECT base in your deployment, the CP935W is the logical choice -- it shares the base's SIP registration without requiring a separate provisioned SIP account.

What works / What doesn't

Australian pricing and where to buy

The CP935W is stocked by Digiphone at around $713 AUD. Because it has built-in Wi-Fi, it does not require a W70B base to operate -- factor in a W70B purchase only if you specifically want to run it in DECT mode alongside existing DECT handsets. For a new meeting room deployment, the CP935W over Wi-Fi is typically the simpler and lower-cost path versus adding a W70B base. If a W70B is already in your deployment for other DECT handsets, DECT mode is also available with no separate SIP account needed.

Verdict

The CP935W is the right conference phone when wireless placement is a genuine requirement -- no patch point at the table, multi-room sharing, or a preference to eliminate cable management from the meeting room. The 6-metre microphone pickup covers standard meeting room configurations, and the DECT wireless link is reliable in normal office environments. The cost is higher than a wired CP925 installation, and it requires a Yealink W70B DECT base. For businesses that already run a Yealink DECT deployment, the CP935W slots in without additional infrastructure. For a new deployment with no existing W70B, evaluate whether the wireless convenience justifies the combined cost versus the CP925.

Frequently asked questions

Does the Yealink CP935W need a base station?

No. The CP935W has built-in Wi-Fi and can register a SIP account directly, without any base station. A W70B DECT base is only needed if you specifically want to run the CP935W in DECT mode alongside existing DECT handsets, sharing that base's SIP registration.

Can the CP935W share the W70B with other DECT handsets?

Yes, in DECT mode. If your deployment already uses a Yealink W70B base station for DECT handsets (W56H, W76P), the CP935W can register to the same base and share its SIP registration. Check the maximum handset registration limit for your W70B firmware version. This is optional -- the CP935W also works standalone over Wi-Fi without a base.

CP935W vs CP925 -- which should I buy?

Buy the CP935W if you need wireless placement (no table cable, multi-room sharing, or cable-free setup) -- it registers over Wi-Fi with no base station required. Buy the CP925 if your meeting room has an accessible patch point and cable management is acceptable, since it costs less. If you already have a W70B base in your deployment, the CP935W can optionally join it in DECT mode instead of using Wi-Fi.

How long does the CP935W battery last?

The CP935W battery supports up to 15 hours of talk time under ideal conditions. It charges in the base cradle when not in use. For a meeting room used for calls during business hours, a single daily charge overnight is sufficient for most usage patterns.
