Ageing OneAccess Gateway? Move to Modern Internet + SIP
On an ageing OneAccess gateway? As carriers retire MPLS and IP VPN, we move you to managed business internet and SIP trunks — numbers kept, cutover planned.
If your business still runs an older OneAccess gateway or router, the ground underneath it is shifting. OneAccess is now an Ekinops brand and the current OneOS6 models are very much alive — but the earlier OneOS5-era units that many Australian businesses inherited on a carrier WAN are now legacy, and the MPLS and IP VPN services they sat on are being retired in favour of internet and SIP. SIP Connect moves you off that ageing kit cleanly, onto modern managed internet with SIP trunks — usually for less than you pay today.
The honest situation
Let's be accurate: OneAccess is not dead. Ekinops (France) owns the brand and still sells and supports current OneOS6 routers and gateways. What is happening is narrower — older OneAccess models from the OneOS5 era are now legacy, and Ekinops points those customers toward its newer OneOS6 products. The bigger shift is the network underneath. OneAccess units were widely deployed as managed CPE on Australian carrier WAN services such as Optus Evolve IP VPN, and as Integrated Access Devices on Telstra business services. As carriers retire legacy MPLS, IP VPN and TDM-voice in favour of NBN, fibre and SIP, that older CPE quietly reaches the end of its useful life on your service — even without a published end-of-life date. Plan now, while you still have choices, and confirm your own device lifecycle with your carrier or the Ekinops MyConnect portal before anyone tells you it's urgent.
Why move with a local team
To be clear, SIP Connect does not sell OneAccess — we specialise in migrating businesses off ageing gateways and routers and onto something built for the next decade. We're vendor-neutral, so we recommend the platform that genuinely fits how you work, not the one we're tied to. We are an authorised Yealink reseller and a 3CX Partner, and when you call you reach a real person in Greensborough — no offshore call centre, no robots. Our team brings over 80 years of combined industry experience, and customers rate us 5.0 on Google.
Your migration options
For businesses leaving an OneAccess gateway behind — especially MPLS, IP VPN or Evolve customers moving to internet plus SIP — we build the replacement around how you actually work:
- Modern business internet — swap the old carrier WAN for business NBN, gigabit fibre or 5G fixed wireless, sized to your sites and monitored by us.
- SIP trunks — replace the voice the old gateway carried with clean SIP, so your calls ride the same modern connection as your data.
- Internet failover — a second path that keeps phones and internet up if the primary link drops, which is exactly the resilience a single ageing router can't give you.
Pair any of these with a modern phone platform — 3CX, a hosted PBX or Microsoft Teams calling — and the whole stack is current and well-supported again.
A migration planned to avoid downtime
We keep your existing numbers, plan the cutover around your trading hours, and switch you over cleanly — often live in days, not weeks. Number porting means your landlines, and any 1300 or 1800 numbers, come across untouched. Coming off a legacy gateway is also the moment to stop overpaying: our bill reviews have identified savings of up to 65%.
One team for phones and the internet underneath
The advantage of replacing an OneAccess box is that one device used to carry both your voice and your data — so the replacement should too. Because we supply the connection your new system runs on as well as the phones on top, the whole setup is tuned to work together, monitored 24/7, and backed by one local team. No finger-pointing between a carrier and a phone vendor when something needs a hand. It's the same single-box-replaced-by-one-team simplicity, just on current, well-supported kit. See our legacy system replacement guide for the full picture, or our Cisco and Telstra DOT pages if those are in the mix too.

Frequently asked questions
Is OneAccess actually end-of-life?
No — not as a brand. OneAccess is owned by Ekinops and current OneOS6 routers and gateways are still sold and supported in 2026. What's legacy is the older OneOS5-era hardware, which Ekinops directs customers to migrate away from. The honest move is to confirm your specific model's lifecycle with your carrier or Ekinops, then plan ahead rather than wait.
I'm on Optus Evolve or a Telstra WAN with a OneAccess device — what changes?
OneAccess units were commonly deployed as managed CPE on services like Optus Evolve IP VPN and as IADs on Telstra business services. As carriers retire legacy MPLS and IP VPN in favour of internet and SIP, that role goes away. We move you to modern business internet with SIP trunks that does the same job for less.
Will replacing the gateway disrupt my business?
Done properly, no. We port your existing numbers, line up the new internet service, and schedule the switch so calls and data keep flowing — most migrations are live in days, not weeks. Your customers won't notice a thing, except that things run smoother.
What will it cost to replace my OneAccess router?
Usually less than you're paying now, once the old carrier WAN and any unused voice services come off the bill. Pricing depends on your sites, your team size and the platform that fits — so the honest way to a real number is a free bill analysis. Send us a recent bill, call 1300 747 266 or contact us, and we'll show you the setup and the savings, with no obligation.
