Business telephony

Hosted PBX and VoIP phones for Australian businesses

Layer 3 is your business phone partner: hosted PBX, number porting, Yealink handsets, and online management for teams in Newcastle, the Hunter Valley, Brisbane metro, and national remote sites. We work with businesses only, scoped around how your team actually answers the phone.

Pair voice with managed IT, on-site rollout, and hardware supply so one team owns the network, handsets, and support path.

What we deliver

  • Hosted PBX & extensions
  • Number porting
  • Yealink handset supply
  • Portal admin & support

Ease of use

Straightforward setup and day-to-day control

Setting up new phones should feel straightforward. We stage extensions, test call flows, and hand over admin access with documentation your office manager can actually use, not a forty-page carrier PDF nobody reads.

Fast start

Simple setup, sensible defaults

We design extensions, hunt groups, and voicemail around how your team actually answers the phone. No generic template pulled from a brochure.

  • Pre-staged handsets that register when they hit your network
  • Softphone and mobile app options for hybrid staff
  • Call flows documented so anyone can follow the logic
  • Training in plain language for reception and managers

Your rules

Customisation without a telecom degree

After-hours routing, public holiday schedules, departmental hunt groups, and music on hold that sounds professional. Not a stock lift playlist.

  • Time-of-day rules per site or team
  • Overflow and failover when lines are busy
  • Per-extension permissions for international or mobile diverts
  • Changes tested before they go live on your main number

Keep your numbers

Porting existing numbers without the drama

Your customers should not need a new main number just because you modernised telephony. Layer 3 coordinates porting of geographic numbers, 1300 and 1800 inbound services, and direct-dial extensions from your current carrier, with a written cutover plan and a sensible backup if timing shifts.

  • LOA and account detail checks done once, correctly
  • Overlap windows where both old and new paths work
  • Test calls before you announce go-live to staff
  • Hunter, Brisbane, and multi-state footprints handled the same way

Hosted PBX

Why hosted PBX beats an on-site phone system

An on-premise PBX tied you to hardware refresh cycles, licence keys, and a single point of failure in the comms cupboard. Hosted VoIP moves the brains to the cloud: lower capital spend, faster changes, and continuity when a site is unreachable.

On-site PBX

  • Up-front hardware and licensing capital
  • You patch, power, cool, and replace the box
  • Capacity upgrades often mean new cards or chassis
  • DR means a second site or crossed fingers

Hosted PBX (VoIP)

  • Predictable per-extension operating cost
  • Platform maintained in geo-redundant datacentres
  • Add lines and sites without rack space
  • Failover and mobile apps built into the model

Align voice resilience with disaster recovery planning when uptime is contractual, not just nice to have.

Yealink handsets

Business phones we supply and support

We standardise on Yealink for reliability, spare availability, and consistent provisioning, supplied through our hardware and software practice with warranty and rollout support.

Desk phones

Yealink T4 and T5 series for reception, accounts, and managers. Colour screens, Bluetooth headsets, and sidecar expansion for high call volume and one-touch BLF keys.

Cordless handsets

DECT cordless for warehouses, showrooms, and clinics where staff move around but still need a proper business handset, not a personal mobile on speakerphone.

Conference phones

Yealink CP series for boardrooms and training rooms. Wide pickup, echo cancellation, and USB or Bluetooth pairing for hybrid meetings.

Microsoft Teams phones

Teams-certified Yealink devices for organisations on Microsoft 365. Shared calendars, presence, and one number whether someone is at their desk or in Teams.

Business continuity

Working from home or another office, same number

When flooding, NBN faults, or urgent projects send staff elsewhere, your phones should move with them. A Yealink desk phone from your Newcastle or Brisbane office can sit on a home router: plug in power and network, wait for registration, and the same extension rings with the caller ID your customers already trust.

Prefer not to move hardware? Softphone and mobile apps keep the extension in a pocket. Hot-desking lets visiting staff log in at any office handset. That is why we treat hosted PBX as continuity infrastructure, not just another phone bill. See top reasons businesses switch to VoIP and pair voice with sensible internet failover in our NBN outage guide.

Online management

Feature-rich portals. Changes without waiting on hold.

Modern hosted PBX includes web administration for the tasks that used to mean a carrier ticket: routing, voicemail, conferencing, and reporting. Layer 3 sets sensible permissions so managers can fix business hours while we keep architecture changes on our side.

Self-service and assisted admin

  • Extension and voicemail management in a browser
  • Call routing, IVR, and time-of-day rules without ticket queues
  • After-hours and public holiday schedules per site
  • Call reporting for billing reconciliation and coaching
  • Hot-desking: log in at any desk phone and your extension follows
  • Conferencing bridges and moderator controls for client calls

Mobile integration

Virtual mobile numbers and on-the-road presence

Virtual mobile numbers let staff present a consistent business mobile identity without carrying a second physical SIM. Calls route through the hosted platform with recording and reporting options where your policy allows. Setup is quick, and monthly cost is typically far less than legacy mobile PBX add-ons.

Existing mobile numbers can often be ported into the same environment as your desk phones, so field teams keep the digits already printed on vans and business cards. Pair with toll-free 1800 or 1300 inbound services for national campaigns while your team stays Hunter or Brisbane based.

VoIP and hosted PBX: common questions

Straight answers before you request a quote. Read our guides on what a VoIP phone is and top reasons to move to VoIP, or browse all Resources.

What is business VoIP?
Voice over IP delivers your phone service across your internet connection instead of legacy copper lines. A hosted PBX runs in the cloud; desk phones, softphones, and mobile apps register securely to it. Call quality depends on good internet, and we help you validate that before you port numbers.
Can we keep our existing phone numbers?
Yes. We coordinate number porting from your current carrier so customers still dial the same main, direct-dial, and toll-free numbers. Porting is planned to minimise downtime, often with a short overlap window while routing cuts over.
Do you supply residential or home phone services?
No. Layer 3 provides business VoIP only for offices, clinics, trades, and multi-site operators across Newcastle, the Hunter Valley, Brisbane metro, and Australia-wide remote deployments.
What internet do we need?
Stable business-grade internet with sensible bandwidth per concurrent call. We review your NBN, fibre, or failover links and can pair VoIP with our networking and support services so voice is not an afterthought on a congested link.
Can staff work from home with the same extension?
Yes. Take a Yealink desk phone home, plug it into internet, and it registers like the office. Or use the mobile or softphone app with the same extension and caller ID. That is core to how we design continuity plans with clients.
How does VoIP relate to Microsoft Teams?
Teams is brilliant for chat and meetings; many businesses still want desk phones and PSTN dial-in. We supply Teams-certified Yealink handsets and can align VoIP with your Microsoft 365 tenant where that is the right fit.
