Business telephony
Business phone systems and hosted PBX for Australian offices only.
Number porting, Yealink desk and Teams phones, virtual mobile numbers, and online call management. Layer 3 designs, supplies, and supports voice across Newcastle, the Hunter Valley, Central Coast, Brisbane metro, and national multi-site footprints without the capital cost of an on-premise PBX.
Business telephony
Layer 3 is your business phone partner: hosted PBX, VoIP, number porting, Yealink handsets, and online management for teams in Newcastle, the Hunter Valley, Central Coast, 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
Ease of use
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
We design extensions, hunt groups, and voicemail around how your team actually answers the phone. No generic template pulled from a brochure.
Your rules
After-hours routing, public holiday schedules, departmental hunt groups, and music on hold that sounds professional. Not a stock lift playlist.
Keep your numbers
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.
Typical porting flow
Audit
List every number, hunt group, fax, and alarm line still in use.
Plan
Agree port date, business-hours impact, and who tests what.
Port
Carrier transfer with Layer 3 monitoring registration and inbound routes.
Verify
Inbound and outbound test matrix signed off before you tell customers.
Hosted PBX
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 Newcastle, Hunter, or Brisbane site is unreachable.
Align voice resilience with disaster recovery planning when uptime is contractual, not just nice to have.
Yealink handsets
We standardise on Yealink for reliability, spare availability, and consistent provisioning, supplied through our hardware and software practice with warranty and rollout support.
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.
DECT cordless for warehouses, showrooms, and clinics where staff move around but still need a proper business handset, not a personal mobile on speakerphone.
Yealink CP series for boardrooms and training rooms. Wide pickup, echo cancellation, and USB or Bluetooth pairing for hybrid meetings.
Teams-certified Yealink devices for organisations on Microsoft 365. Shared calendars, presence, and one number whether someone is at their desk or in Teams.
Handset lineup
Most sites end up with a mix: a couple of premium handsets where video and screen real estate matter, and a consistent workhorse everywhere else. Here is how we usually split the range, with links to Yealink's own specifications if you want the full detail.
Best for: Directors, executives, and anyone who wants video from the desk phone
The top of the range. A large adjustable touch screen and built-in HD camera mean desk-based video calls without a headset-and-laptop juggle, and the cordless Bluetooth handset lets someone keep talking while they walk to the printer.
Big screen, no camera
Best for: Reception, service desks, and high call volume
A large touch screen without the camera. Ideal where someone is transferring calls all day and wants a clear view of who is on hold, who is free, and which line is ringing.
Wireless ready
Best for: Managers and desks where running new cable is awkward
The mid-range pick with wireless built in. Handy for home offices, fitted-out heritage buildings, and any desk where you would rather not chase a data point across the floor.
Standard workhorse
Best for: General desks, accounts, clinics, and volume rollouts
A strong option for standard non-video users. Everything a normal desk needs, nothing it does not, which keeps per-seat cost sensible when you are fitting out twenty desks rather than two.
Hardware-level security
The current range uses trusted-execution hardware encryption and modern TLS, so handsets are not the weak link on your network.
Zero-touch provisioning
We pre-stage configuration centrally. Phones power on, pull their profile, and register without anyone reading a manual.
One template across models
A shared provisioning template across the T7 range means mixing screen sizes on one site does not multiply the admin.
Specifications above are summarised from Yealink's official product pages; full datasheets are published in the Yealink support portal. Cordless DECT, conference, and Teams-certified models are available too, so tell us how your team works and we will match handsets to desks.
Hosted PBX plans
We do not publish a one-size price card. Plans are scoped around extension count, concurrent calls, sites, and handsets, then quoted after a short discovery so Brisbane SMBs and Hunter clinics are not shoehorned into the same package.
Reception, accounts, and a handful of desks that need a proper business phone system without a cupboard full of PBX hardware.
More concurrent calls, departmental queues, and softphones or apps for staff who are not always at a desk.
Newcastle, Hunter, Central Coast, Brisbane, or remote sites under one dial plan with consistent caller ID and support.

Business continuity
When flooding, NBN faults, or urgent projects send staff elsewhere, your phones should move with them. A Yealink desk phone from your Newcastle, Central Coast, 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
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
Mobile integration
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 Newcastle, Hunter, Central Coast, or Brisbane based.
