INSTALLATION SYDNEY
Every Socket Rings.
Every Call Connects.
SECURE A COM provides professional phone line installation across Sydney, connecting existing phone sockets to your NBN router so every handset in the property carries a live dial tone. For FTTN and FTTC connections, the router's VoIP port signal is routed through the second pair of the lead-in cable to each wall socket. All phone line installation work is quoted individually, backed by a 12-month workmanship guarantee from Open Registered Cabler A10089 via ASIAL.
WHY YOUR PHONE SOCKETS
STOPPED WORKING WITH NBN
When NBN replaces the old copper telephone network, existing phone sockets throughout the property lose their dial tone — but the router sitting in the lounge has a working phone port the whole time. Here are the five most common phone line installation problems we see across Sydney every week.
NBN Installed But Phone Sockets Are Dead
Only One Room Has a Working Phone
Call Quality Is Poor or Drops Out
Home Office Needs Additional Phone Points
FTTC or FTTN Socket Configuration Is Wrong
WE WIRE IT.
YOU ANSWER IT.
EVERY TIME.
Every phone line installation is assessed on-site before a single cable is touched. We identify your NBN type, trace your existing copper pairs, and determine the most efficient wiring approach — then quote before starting any work.
WATCH HOW WE RESTORE PHONE SOCKETS AFTER NBN HFC
Phone sockets commonly stop working after an NBN HFC cutover — and ISPs rarely fix it. The old Telstra copper lead-in is often left active with 52 volts still feeding from the exchange. These are real jobs where a licensed cabler was the only way to get every socket working again.

Getting a phone line installation right means understanding your NBN connection type, your existing socket layout, and how your router's VoIP port is configured — before a single cable is touched. Here's exactly what happens when you contact SECURE A COM for a phone line installation across Sydney.
Enquire and Receive a Written Quote
Every phone line installation starts with a brief discussion — not a booking. Because every property has different socket layouts, NBN connection types, and router positions, we discuss requirements before quoting. Tell us your NBN type — HFC, FTTC, FTTN, or FTTP — how many sockets you want connected, and where the router currently sits. We use this to calculate the cabling approach, materials required, and total cost. You receive a clear written quote before any work is scheduled. Most phone line installations across Sydney are straightforward and quote quickly. Once you approve the quote, we schedule a time and send a confirmation with your technician's details.
On-Site Assessment Before Any Cable Is Run
Your Open Registered Cabler arrives and begins with a full property assessment before touching any cabling. We locate your NBN router, confirm the phone port is active and delivering a live dial tone, then trace every existing telephone pair throughout the property. For FTTC and FTTN homes, we identify the lead-in copper cable and confirm which pairs are available for VoIP distribution. We note every existing phone socket location, assess whether the current internal wiring is suitable for reuse, and confirm any additional cable runs required to reach sockets that cannot be served from the existing pairs. This assessment forms the basis of the installation plan executed during the same visit.
Cabling and Socket Termination to Standard
With the assessment complete, we carry out any necessary cable runs — through ceiling cavities, wall spaces, or in surface conduit where required — to reach each phone socket location cleanly. New cable is telephone-grade and run with fixings or concealment wherever accessible. Every socket is terminated using a Krone punch-down tool to AS/CA S009:2020 standard, ensuring a clean connection without twisted pairs or unterminated stubs that would introduce noise or impedance mismatch. Where existing sockets are wired in an old ring-main configuration — common in Sydney homes built before 2000 — we rewire to a star configuration from the router position, eliminating the bridge taps responsible for VoIP audio degradation and call dropout across multiple handsets on the one line.
VoIP Signal Distributed Through the Property
Connecting existing sockets to the router's VoIP phone port requires a different wiring approach depending on the NBN connection type. On HFC and FTTP connections, we run a pair directly from the router's phone port back through the internal cabling to every socket in a star or home-run configuration. On FTTC and FTTN connections, the lead-in copper cable carries two separate pairs: the primary pair terminates at the first socket for the router's VDSL data signal, while the secondary pair becomes the return circuit distributing the router's VoIP dial tone back through the house to every socket. This dual-pair configuration ensures NBN data and phone service operate correctly without interfering with each other — both in signal quality and regulatory compliance.
Every Socket Tested — Walkthrough Before We Leave
Before the visit ends, every phone socket in the property is tested for live dial tone using a handset and line tester. We then place a test call from an external number to confirm the phone rings at every connected point simultaneously — as it should. Call audio is checked at each socket for crackle, noise, or low volume that might indicate a termination issue or residual impedance mismatch from an unterminated stub. If any socket fails the ring test or shows audio issues, we identify and correct the cause before leaving. You receive a verbal handover confirming what was installed, how the configuration works, and what to do if any issue arises within your 12-month workmanship guarantee period.

QUESTIONS
Everything Sydney homeowners and businesses ask before booking a phone line installation. If your question is not here, call us directly.

When NBN is installed, the Telstra copper network connection to your property is disconnected at the lead-in cable or at the street-side MDF. This removes the analogue PSTN dial tone from your internal wiring entirely — every phone socket in the house goes dead. To restore a working dial tone, the internal copper wiring must be reconfigured to carry the VoIP signal from your NBN router's phone port to each socket. This is a standard phone line installation job carried out by an Open Registered Cabler — it is not covered by the NBN Co connection process.
Phone line repair addresses faults in existing, previously-working telephone wiring — broken pairs, corroded terminations, damaged sockets, or water ingress. Phone line installation is a new or reconfigured wiring job where internal cabling is set up to carry a VoIP signal from your NBN router to each phone socket in the property.
If your sockets were never connected to NBN VoIP, that is an installation job. If they were working on NBN and then stopped, that is a repair job. SECURE A COM handles both — see our phone line repair page if your sockets were previously working on NBN.
Most NBN routers supply one FXS (foreign exchange station) port for VoIP. The number of physical sockets it can drive depends on the ringer equivalence number (REN) of each handset. Most handsets carry a REN of 0.1 to 1.0, and most routers support a combined load of up to 5 REN.
In practice, a single VoIP port can support four to six standard corded handsets, or a DECT cordless base station plus several additional corded handsets. We confirm your router's output capacity during the on-site assessment and configure the wiring accordingly.
Yes — DECT cordless phone systems are fully compatible with NBN VoIP. The base station connects to a wall socket carrying the VoIP dial tone from your router, and all registered handsets work exactly as they did on the old PSTN network, including incoming ring and outgoing calls.
If your DECT system has multiple handsets registered to a single base station, only the base station contributes to the REN load — not each individual handset. DECT is the recommended solution for whole-of-property phone coverage from a single VoIP connection, and we can advise on base station placement during the installation visit.
Yes. Installing new phone socket outlets in rooms that lack existing phone points is a standard part of the phone line installation service. New cable is routed from the nearest existing point or directly from the router's VoIP port, run through ceiling and wall cavities where possible to minimise visible conduit. All new sockets are Krone punch-down terminated and tested for dial tone before we leave.
We quote new socket installation based on cable run length and access difficulty. Multiple new sockets can be installed in a single visit. Contact us to discuss your requirements before booking.
All phone line installation work is carried out to AS/CA S009:2020 — the Australian standard for customer cabling. This standard specifies cable type, socket placement, termination method, wiring configuration, and testing requirements for telecommunications cabling in residential and commercial premises. Compliance is a legal requirement for any registered cabler in Australia.
SECURE A COM holds Open Cabler Registration A10089 via ASIAL, an official national cabling registrar accredited by the Australian Communications and Media Authority (ACMA). All installation work is backed by a 12-month workmanship guarantee referenced to your cabler registration number.
Number porting — transferring your existing landline number to a VoIP service — is managed by your telephone service provider, not by the cabling technician. Most major providers support number porting for residential and business lines, and the process typically takes a few business days once requested. Your current provider or NBN phone service provider can advise on eligibility.
SECURE A COM's role is to ensure your internal cabling is correctly configured so that the VoIP service works from every phone point in your property once the number port completes and your service is active. Wiring and porting are separate processes.
No. NBN Co installs the equipment at the premises boundary — the NTD or FTTC connection point — and your RSP connects your router to that equipment. Neither NBN Co nor your RSP is responsible for the internal telephone wiring inside your property.
Connecting your existing phone sockets to the router's VoIP port, running new cable to additional phone points, and configuring your internal wiring for VoIP are all customer-side tasks outside any NBN service contract. This work must be carried out by a registered cabler — exactly the phone line installation service SECURE A COM provides across Sydney.
