Modern business phones are network devices — which means the phone vendor who can't test a cable run is selling you half a system. We install business phone systems the infrastructure-first way: cabling verified, PoE budgeted, power protected, handsets configured, and your old PABX system retired without a single missed call.

The business phone system used to be its own little kingdom — copper pairs, a PABX system in the cupboard, a specialist with a briefcase. That world is gone: modern office phones are VoIP devices on your data network, calls travel the same cabling as your email, and the phone system's reliability is exactly the reliability of the infrastructure underneath it.
Which is why Unified Network Solutions installs business phone systems from the infrastructure up: the cabling behind every handset verified or installed (ACMA Open Cabler #42489), the PoE budget calculated before twenty phones hit one switch, power protection sized so a brownout isn't a missed-order afternoon, and the handsets configured and cut over without your incoming number ever ringing out. We carry no telco plan commissions — the system gets installed right, and you choose whoever you like for the calls.
The NBN transition retired the copper phone network suburb by suburb, and every Brisbane small business phone system has felt it somewhere between the disconnection notice and the dead dial tone: the old lines stopped, the PABX lost its diet, and "NBN business phone system" became the search of necessity. The good news is the replacement architecture is genuinely better — when it's installed by someone who understands what it depends on.
A VoIP office phone system over your NBN service means calls as data — the modern nbn business phone system: handsets on your network, numbers hosted with a provider, features (voicemail-to-email, mobile twinning, auto-attendants) that the copper era charged dearly for. The dependency is the catch — your phones now inherit every weakness of your network and power.
So our installs close those weaknesses first: the data cabling each handset rides tested to spec, voice traffic prioritised on the network, the NBN equipment and switch on a UPS, and failover-to-mobile configured for the outages beyond anyone's control. Phones built for the network they actually live on.
Brisbane's cupboards still hold hundreds of PABX systems — and every PABX system there is running on borrowed time. Migrating one to an nbn business phone system is a sequence, not a swap.
Audit what the PABX actually does. Twenty years of extensions, hunt groups, door phones, and fax lines accumulate undocumented. We map the old system's real behaviour first — the features people rely on are always the undocumented ones.
Port, then cut over. Numbers ported to the VoIP provider on a planned timeline, the new system running in parallel, and the cutover moment chosen — never discovered. Incoming calls don't ring out during our transitions.
Decommission with respect. The old PABX system and its wall of jumper wire removed, the comms space reclaimed, and any worthwhile legacy cabling identified for reuse — the frame work done by people registered to touch it.
Telephone point installation, handset supply, and network configuration have traditionally been three separate purchases — which means the traditional phone system involves three vendors pointing at each other: the dealer who sold the handsets, the cabler who ran the points, and the IT provider whose network carries the blame. When a phone crackles, the triangle starts.
We collapse it to one phone number. The handsets, their configuration, the telephone point installation behind each desk, the patch panel they terminate to, and the network settings that keep voice clean under load — one contractor, one warranty conversation, one accountable party when anything needs attention.
For offices mid-fitout, the phone system folds into the data package — points cabled at rough-in, handsets deployed at final fix, and the whole voice layer documented in the same handover pack as everything else.
The small business phone system and office phone system question isn't "which brand" — it's "what do your calls actually do all day." The common Brisbane shapes:
Two or three handsets, calls that must reach a human, and mobile twinning so the office number rings the ute. Small, robust, and failover-first — the system disappears into the workflow.
Reception-heavy call flow: auto-attendant, hold queues that don't enrage, and handsets that integrate with the booking workflow. Call recording where compliance wants it.
An office phone system with direct-in-dial for every desk, presence so reception sees who's free, and Teams integration where the calls and meetings should share one identity.
Sales and support floors where the phone is the job — wallboards, queue analytics, supervisor tools, and headset-first handsets specified for all-day wear.
Loud environments and roaming staff: rugged or cordless IP handsets, overhead paging tied into the system, and coverage engineered with the site WiFi.
One phone system across every location — free internal calls between sites, one reception able to answer for all, and a single management pane instead of per-site chaos.
A business phone system is judged on its worst day, not its demo. The disciplines that decide it:
Every handset's run tested — marginal cable that survives email corrupts voice, and crackle complaints are cabling complaints wearing a headset.
Twenty handsets drawing power from one switch is arithmetic someone has to do — we do it at design, so phones don't brown out when the APs wake up.
QoS configured so a big file transfer never crunches a client call — the network setting most phone installs skip and most call-quality complaints trace to.
The connectivity chain on a UPS — because a VoIP system without one converts every brownout into a missed-call afternoon.
Outage beyond the UPS? Calls divert to nominated mobiles automatically — customers reach a human either way, and never learn you had a bad day.
Extensions, points, and config recorded — so the next change is administration, not archaeology, whoever performs it.
Handsets needed, the current system's real behaviour mapped, and the cabling each phone will ride checked — the quote built on facts.
Cabling fixed or installed, handsets deployed and configured, the network's voice settings done — priced per handset, no surprises.
Numbers ported on a planned timeline, both systems live through the transition, and the cutover moment chosen for your quietest hour.
Test calls in and out, failover tested for real, documentation delivered — and the old PABX system leaves the building with dignity.
Because the phone system's failures are infrastructure failures — and we're the infrastructure trade.
ACMA Open Cabler #42489 — the registration the physical phone work legally requires, and the trade knowledge that makes VoIP behave.
No telco kickbacks, no plan margins — the system recommendation serves your call patterns, and the provider choice stays yours.
Phone systems installed to slot into your MSP's management — or white-label deployments under their brand, our hands.
A modern VoIP business phone system for a small Brisbane office — quality handsets, the system configured, cabling verified or installed — typically runs $250–$500 per handset installed, plus whatever monthly call plan you choose with your provider. A ten-phone office usually lands $3,000–$5,000 for the physical and setup side. No hardware lock-ins or plan commissions from us — fixed install pricing, call Chris on 0412 853 618.
A VoIP system, almost certainly. The copper services old PABX systems relied on have been switched off — the nbn business phone system era replaces them, and the transition, and the replacement is IP telephony: handsets running over your data network, a cloud or on-site system, and your numbers ported across. The replacement is usually cheaper to run than the PABX was, with more features — and we handle the decommissioning of the old system and the cutover without dropping your incoming calls.
Yes — that's the modern architecture. An office phone system now runs as VoIP over your NBN data service — the nbn business phone system pattern: the handsets connect to your network, calls travel as data, and your numbers live with a VoIP provider rather than on copper pairs. The catch is dependency: the phones are only as reliable as the network and power under them, which is why our installs include the cabling verification, PoE budgeting, and UPS conversation most phone vendors skip.
Yes — numbers port between providers under Australian portability rules, including from old copper services to VoIP. The porting process has lead times and one brief cutover moment, both of which get planned so incoming calls never ring out unanswered. Whatever provider you choose for calls, the porting fits into our installation timeline.
Because modern business phones are network devices, and their failures are nearly always physical: a marginal cable run, an exhausted PoE budget, a network that drops voice packets under load. Telco dealers sell systems and assume your infrastructure; we verify and fix the infrastructure as part of the install — registered cabling work included (#42489). The result is phones that keep working after the demo.
Without planning, VoIP phones die with the power — handsets, switch, and NBN equipment all need electricity. The fix is a properly sized UPS on the connectivity chain (we install these) plus call-forwarding failover to mobiles configured in the phone system, so outage calls divert instead of ringing out. Five minutes of configuration that saves entire trading days.
No — deliberately. We install and cable the system, configure the handsets, and make the physical layer bulletproof; you choose the VoIP provider and plan that suits your call patterns (we'll explain the options honestly, having no commission in the game). It keeps our advice clean and your monthly costs negotiable.
We service Brisbane CBD, North Brisbane, South Brisbane, Gold Coast, Sunshine Coast, Ipswich, Logan, Moreton Bay, Redlands, and the wider South East Queensland region. For larger projects, we can service regional Queensland by arrangement.
Yes — for offices already living in Teams, calling can run through it (Teams Phone with calling plans or direct routing), with physical handsets for the desks that want them and the boardroom gear sharing the same identity. Whether Teams-as-the-phone-system or a dedicated VoIP platform suits you better depends on your call patterns and licensing — we'll lay out both honestly, since we sell neither plan.
A small business phone system — handsets deployed, configured, cabling verified — is typically a single day on site. The number porting runs on the providers' timeline (commonly one to three weeks), with your old service staying live until the planned cutover moment. Larger systems and multi-site rollouts are programmed per project, and PABX decommissioning adds a half-day at the end.
Business phone systems Brisbane companies actually rely on: small business phone system installs, office phone system fit-outs, NBN business phone system migrations and PABX system replacements across Brisbane CBD and metro, Logan, Ipswich, Redlands, Moreton Bay, the Gold Coast, and the Sunshine Coast — three-handset shopfronts, fifty-extension offices, and the cutovers in between. Installed on certified cabling, protected against the grid's moods, and cut over without a missed call. The phone system is how customers reach the business — it deserves infrastructure-grade treatment, and that's the only grade we install.
Tell us the handset count and what's limping along now — we'll quote the install fixed, port the numbers without drama, and leave you with telephony built like infrastructure.
