Quick answer
- Best all-round desk phone: Yealink T54W (~$289–330). Best speakerphone: Poly Edge E450 (~$327–359). Best value: Grandstream GRP2634 (~$129–210) or GRP2602P (~$62–85).
- For a reception desk with lots of BLF keys: Yealink T46U/T54W, Fanvil X6U (~$252) or Grandstream GRP2670 (~$249).
- For walking around: Yealink W76P DECT kit (~$159–199). Wi-Fi only if you must: Grandstream WP822 (~$169).
- “Reception” in VoIP is not radio reception. There is no SIM or aerial: the phone is only as good as the Ethernet/Wi-Fi/DECT link, the codec and the provider path.
- Providers do differ — mainly codec policy, transcoding, POP/peering, jitter handling and whether they let you control codecs. But handset, LAN and NBN usually matter more.

The chain, not the box
VoIP quality is a chain with five links:
- microphone, speaker and echo canceller
- codec
- local network
- provider and transcoding
- destination network (PSTN or mobile)
A $400 phone on bad Wi-Fi will sound worse than a $90 phone on a cable. That is not a slogan; it is the most common support ticket in the category.
Wideband (“HD voice”) only survives if both endpoints and every network in between negotiate it. Australian fixed networks default to G.711a; mobile networks default to AMR narrowband (Communications Alliance G672:2023). So calls to mobiles are usually narrowband no matter what phone you buy.
Internal calls — extension to extension, same platform — are where G.722 and Opus actually shine.
What you can control: handset acoustics, wiring, QoS, codec order, provider choice, and the destination (mobile vs fixed vs internal). What you cannot control: the mobile network at the other end.
The terms, measured properly
Full duplex. Both sides can talk at once; half-duplex clips. Look for “full-duplex speakerphone” and acoustic echo cancellation (AEC) in the datasheet, not the marketing page.
HD voice / wideband. G.722 at 16 kHz sampling, roughly 7 kHz of audio, about 64 kbps — same bitrate as G.711, so it costs nothing extra on the wire.
Opus. 6–510 kbps adaptive, with forward error correction; best on lossy links. Supported by better phones and some providers, but not universal on desk phones, and often transcoded at the PSTN edge.
MOS. G.711 ≈ 4.2, G.722 4.1–4.5, Opus 4.3–4.9, G.729 ≈ 3.9. These are lab scores, not guarantees of what you will hear on a Tuesday at 10am.
Noise suppression. Poly Acoustic Fence / NoiseBlockAI, Yealink Acoustic Shield, Snom and Cisco equivalents. It matters in open-plan offices and almost nowhere else.
Speaker wattage is rarely published. Do not trust a dB claim without a datasheet. Bigger housings and dedicated conference phones beat any desk phone for group calls.
Headset beats handset for all-day use: RJ9, USB or EHS. A $150 headset often improves perceived quality more than a $150 phone upgrade.
Editorial ranking (subjective)
Poly Edge E series → Yealink T5x/T4x → Cisco 8800 / Snom D8xx → Grandstream GRP / Fanvil → budget T3x → DECT handsets (small speakers; use for mobility, not conference). This ordering is our opinion from the specs and hands-on reports, not a measurement.

Three different problems wearing one word
- Front-desk reception. Needs BLF keys, transfer, a headset and a loud handset. Picks: T54W/T46U, Fanvil X6U, GRP2670, Poly E450. Add EXP50 or EXP43 sidecars past 15 extensions.
- Radio/coverage reception. There is no RF in VoIP. DECT runs at 1.9 GHz with ~50 m indoor and ~300 m outdoor range; warehouses need multi-cell. Wi-Fi needs 5 GHz, WMM/QoS and good roaming. Wired Ethernet always wins. PoE 802.3af and a UPS keep it alive in an outage.
- How you are heard at the other end. Mic placement, echo cancellation, background noise. Speakerphones in open offices pick up HVAC and keyboards; a headset fixes it.
Do providers actually differ? Yes — but not how most people think
“The internet is the same” is only half true. You buy the same NBN line, but you do not buy the same path, the same codec policy or the same transcoding.
| Provider | What they are | Codec notes | Why it matters |
|---|---|---|---|
| Crazytel | SIP trunk / CrazyPBX, Brisbane; POPs in Sydney, Melbourne, Brisbane, Perth, NZ, LA | publicly documents G.711a/µ; G.722 not declared | reliable narrowband, cheap, multi-POP; no HD between endpoints |
| MaxoTel | hosted PBX / SIP trunk, Melbourne, AU support | G.722 supported alongside G.711; UDP only | good SMB fit, HD possible, simpler network |
| SIPcity | trunk / PBX, AS63971, Equinix Fabric peering | G.722, Opus, G.711, G.729, iLBC; TLS/SRTP | strongest codec and security menu, good for HD |
| MyNet (mynet.au) | SIP trunk | prefers G.722, then G.711a/µ; DSCP EF/CS3 guidance | QoS-aware, AU-only geo-lock |
| Telnyx | global CPaaS with AU numbers | G.722 HD voice on AU numbers since Oct 2025; Opus with SRTP | good for integrations, not a handset-and-support vendor |
| Aussie Broadband | ISP + business SIP trunks; owns Symbio/MNF wholesale | codec support varies by product — ask | one throat to choke, strong AU network |
| Telstra | Business SIP / SIP Connect | G.711 baseline; accredited on-prem PBX, not cloud PBX | premium support, least flexible |
| VoIPLine Telecom | hosted | Opus preferred internally, G.711 to PSTN | great extension-to-extension, normal external |
| Click2Call | hosted | G.722 / G.711 / G.729, 20 ms ptime | simple quality presets |
| Teams Phone / Zoom | UCaaS | Opus internally; PSTN breakout often G.711/AMR | best internal, mobile calls still narrowband |
| Compiled from provider documentation and published network notes. Codec menus change; ask for the current list. | |||
The seven differences that matter
- Codec menu and default order. If G.729 is first, you get narrowband by default.
- Transcoding at the edge. G.722 in, G.711 out, is still G.711 to the person you called.
- POP location and peering. Sydney vs Los Angeles is 150 ms of latency before anything else goes wrong.
- Jitter buffer, packet loss concealment, congestion engineering. Invisible until the network is busy.
- QoS and whether DSCP EF is honoured. Many providers mark, few police.
- Encryption and transport. TLS/SRTP versus UDP-only.
- Commercial support, and whether you can change codecs at all. Some portals have no codec page.
For most Australian SMBs the impact order is: handset/headset > LAN/Wi-Fi > NBN access type > provider path > codec. But two providers on the same NBN line can sound different at peak if one forces G.729, transcodes, or routes via a distant POP.
Three questions to ask any provider: Do you support G.722? Do you transcode to G.711 at the PSTN edge? Where is your nearest media POP?
What a call actually sounds like
| Call type | Typical codec | What to expect |
|---|---|---|
| Extension to extension, same platform, both HD phones | G.722 or Opus | best case; noticeably clearer |
| VoIP to fixed line in AU | G.711a | good narrowband; no HD benefit |
| VoIP to mobile | AMR-NB via PSTN/mobile gateway | narrowband; handset and network matter more than codec |
| VoIP to overseas fixed | G.711 or G.729 depending on carrier | variable; latency and transcodes dominate |
| Conference call / speakerphone | G.722 if all endpoints support it | room acoustics and speaker quality dominate |
| Teams / Zoom internal | Opus | excellent; PSTN dial-in is the weak link |
Twelve things to do before you blame the phone
- Wire it. Ethernet plus PoE. Never Wi-Fi for a primary reception phone.
- Codec order. G.722 → G.711a → G.711u; drop G.729 if upload is fine; Opus only if the provider supports it end to end.
- ptime 20 ms and DTMF RFC 4733.
- Disable SIP ALG on the router. Test before and after — it commonly breaks one-way audio.
- QoS. DSCP EF (46) for RTP, CS3 (24) for SIP, and set trust boundaries on the switch.
- VLAN for voice if you have managed switches.
- Keep upload headroom. About 100 kbps per concurrent call, plus 30–50%.
- Test. Latency under 150 ms one-way (ideally under 80 ms), jitter under 30 ms, loss under 1%.
- Firmware and auto-provisioning. Confirm the exact model is supported by your provider.
- Headset. RJ9, USB or EHS — match the cable to the phone.
- UPS on NBN NTD, router and PoE switch. Keep a mobile for 000 fallback.
- On FTTN, HFC or fixed wireless, test at peak. Consider G.729 only as a last resort.
Buying in Australia
- Buy Australian stock with the RCM mark. Warranty is typically 12–24 months. Grandstream’s warranty policy excludes some marketplace sales.
- Retailers: MSY, Umart, Mwave, Scorptec, SkyComp, JW Computers, Device Deal, VTech, MegaBuy. Providers such as MaxoTel sell pre-provisioned units.
- A PoE injector is $20–50 if your switch is not PoE.
- Prices are one-off. Provider plans are separate and usually per user or per channel.
- 000 and IPND: register the service address. VoIP needs power and internet, so have a fallback.
- Do not buy a consumer Panasonic or Uniden DECT phone expecting SIP. It needs an ATA and is not a business endpoint.
What we would buy
- One phone for a busy desk or reception: T54W.
- Best sound above all: Poly Edge E450.
- Tight budget: GRP2602P or T31P.
- Walking around: W76P.
- Provider: pick one that supports G.722, has an AU POP and lets you set codec order. Then fix the LAN before blaming the phone.
