The CP925 is Yealink's room-based VOIP conference phone. A standalone unit designed for meeting rooms that need a dedicated VOIP call device rather than relying on a laptop and USB speakerphone. It has a 3.1" touchscreen, PoE, OPUS HD audio, and an omnidirectional microphone array designed for rooms with 4-8 people around a table.

Who is this phone for?
The CP925 is a meeting room phone. It sits in the centre of a conference table and handles VOIP calls for the whole room. It is not a desk phone for individual use. The use case is a dedicated meeting room that regularly hosts conference calls with external parties: client calls, supplier negotiations, team calls with remote staff, or any meeting that requires clear audio from multiple participants around a table.
Why a dedicated conference phone rather than a laptop and speakerphone app: a dedicated VOIP conference phone registers as a direct SIP extension on your hosted PBX. This means the meeting room has its own phone number, call history, and voicemail. Calls are routed through the business phone system rather than a personal account. Audio quality from a purpose-built microphone array consistently outperforms the USB speakerphone option in a room environment.
Room size considerations: the CP925 is rated for small-to-medium meeting rooms with 4-8 people. For larger boardrooms (8+ people around a long table), the CP965 or CP960 with expansion microphones is a better fit. For small 2-4 person huddle rooms, the CP925 is well-matched.
Alternative: if the meeting room already has a video conferencing platform (Zoom Rooms, Teams Room) provisioned on dedicated hardware, a separate VOIP conference phone may be redundant. The CP925 is primarily for rooms running hosted PBX calls rather than video conferencing platform-routed calls.

Build quality and design
The CP925 has the form factor typical of Yealink conference phones. A low-profile disc unit that sits flat on a conference table. The 3.1" touchscreen faces upward for operation from any seat around the table. The capacitive touch interface handles dial, hold, mute, volume, and call management without physical buttons cluttering the unit.
The omnidirectional microphone array is designed for 360° pickup across a table. Yealink rates the effective range at approximately 2 metres radius from the unit. Adequate for a standard 4-8 person meeting room. The full-duplex audio processing suppresses echo and background noise, which matters for any room with hard surfaces (glass walls, tiled floors) that create reflections.
PoE powers the unit from the Ethernet cable. Ethernet connectivity is wired only. The CP925 does not have Wi-Fi. The meeting room needs an Ethernet port at the table, or a cable run from a nearby wall port to the centre of the table.
Call quality on Australian NBN
OPUS and G.722 HD audio deliver noticeably better voice quality than standard G.711 on well-configured NBN connections. In a meeting room context, HD audio is particularly valuable. Remote participants sound clearer, and the full-duplex noise suppression reduces the fatiguing quality of long conference calls.
The CP925 connects via wired Ethernet. Which is the correct approach for a conference phone. A meeting room phone on Wi-Fi introduces unnecessary jitter risk for calls where multiple people are relying on audio quality. If the meeting room does not have Ethernet, running a cable to the table is the right solution before deploying a conference phone.
Ensure SIP ALG is disabled on the router. Conference phones are subject to the same SIP ALG one-way audio issues as desk phones.
Features
The CP925's feature set is purpose-built for room-based conference calling:
360° omnidirectional microphone. Picks up voices from all seats around the table. Rated for 4-8 person rooms. Full-duplex operation allows simultaneous speaking and listening without cutting out.
3.1" touchscreen. Touch-operated call controls (dial, hold, mute, transfer, volume). Faces upward for access from any seat.
OPUS and G.722 HD audio. HD codec support for clear conference call quality on NBN connections.
PoE powered. Single Ethernet cable handles both network connection and power. Clean table installation without a separate power adapter.
USB expansion port. Supports Yealink CPW25 wireless expansion microphone for larger rooms. One expansion microphone extends pickup to rooms up to 16 people.
1 SIP account. Registers as a standard extension on your hosted PBX. The meeting room has its own number, call history, and voicemail.
Yealink RPS auto-provisioning. Compatible with AU hosted PBX providers for zero-touch setup on first boot.

Australian pricing and where to buy
The CP925 retails around $539 AUD from Australian ICT and communications retailers. Pricing updates nightly on this page from StaticICE AU data. Also available on Amazon AU for single-unit purchases.
For multi-room deployments, contact your SIP provider or Yealink's AU distribution channel. The optional CPW25 expansion microphone is available separately for larger room coverage.
The CP925 is the right choice for a 4-8 person meeting room that needs a dedicated VOIP conference phone on a hosted PBX. The audio quality, PoE convenience, and direct SIP extension registration make it a significantly better experience than routing meeting room calls through a laptop or USB speakerphone.
For larger boardrooms, look at the CP965 or CP960 with expansion microphones. For smaller huddle rooms where call quality requirements are lower, a DECT handset or USB speakerphone may be more cost-effective. At AU$539, the CP925 is the right specification for a room that is actively used for external client calls where audio quality reflects on the business.
Frequently asked questions
How many people can the Yealink CP925 accommodate in a meeting room?
The CP925's microphone array is rated for 4-8 people in a standard meeting room (approximately 2-metre pickup radius). For larger rooms or long boardroom tables, the optional CPW25 wireless expansion microphone extends coverage to rooms with up to 16 participants.
Does the Yealink CP925 need Wi-Fi or Ethernet?
The CP925 requires a wired Ethernet connection. It does not have Wi-Fi. This is the recommended approach for conference phones: wired Ethernet provides more consistent audio quality than Wi-Fi for room-based calls. Ensure the meeting room has an Ethernet port accessible at the conference table.
Is the Yealink CP925 compatible with Maxotel and other AU hosted PBX providers?
Yes. The CP925 registers as a standard SIP extension on any hosted PBX, including AU providers like Maxotel, SIPcity, and VoIPline. Yealink RPS auto-provisioning is supported for compatible AU providers.
Can the Yealink CP925 be used for Zoom or Teams calls?
The CP925 is a SIP VOIP conference phone, not a Teams Room or Zoom Room device. It handles calls routed through your hosted PBX. For Microsoft Teams or Zoom video conference calls, you would need a Teams-certified or Zoom Rooms device instead. The CP925 is the right choice for PSTN/SIP conference calls through your business phone system.
What is the difference between the Yealink CP925 and CP965?
The CP965 is a higher-tier conference phone with a larger 5" colour touchscreen, Wi-Fi and Bluetooth support, and a more powerful microphone array for larger rooms. The CP925 is wired-only with a 3.1" screen and suits 4-8 person rooms. The CP965 suits larger boardrooms and rooms that need wireless connectivity.
