Your Cisco 800 Router Is End of Life — Plan the Move While You Still Can
Still running a Cisco 880, 887, 891 or C819 router? It's past Cisco support and no longer patched. We move you to a managed, monitored router.
If your office still runs on a Cisco 800-series router — a 880, 881, 886, 887, 891, 892 or C819 — you are leaning on hardware Cisco no longer sells or supports. These routers reached the end of their lifecycle through Cisco's normal product retirement, and most no longer receive software updates or security fixes. SIP Connect moves you off ageing Cisco gear cleanly, onto fully-managed, monitored business internet running on a modern, currently-supported router.
The honest situation
Cisco's entire classic 800-series Integrated Services Router line is past End-of-Sale and is no longer sold by Cisco. Cisco stopped selling the 881, 887 and 898 on 29 October 2020, with the Last Date of Support reached on 31 October 2025 (Cisco bulletin EOL13392). For the 886, 887, 897, 898 and 899, Cisco ended security and vulnerability support on 29 April 2023 and the Last Date of Support fell on 30 April 2025 (bulletin EOL13227). The select 891 and 892 models went End-of-Sale back on 3 July 2014, with support ending 31 July 2019.
The practical risk is simple. Once a router passes its End of Vulnerability/Security Support date — 29 April 2023 or 29 October 2023 depending on the 887 variant — Cisco stops releasing security patches for it. Any new flaw found after that point is never fixed on the device. Running a Cisco 887 or similar 800-series router in 2026 means operating end-of-life hardware with no software updates and no security cover, which is a recognised security and compliance risk for Australian businesses. Your internet won't drop overnight, but the gear underneath it is frozen in time — and waiting only shrinks your options.
Why move with a local team
To be clear, SIP Connect is vendor-neutral — we don't sell the legacy brands. We specialise in moving businesses off ageing, unsupported routers and onto a platform built for the next decade, so the advice you get is honest rather than tied to one box. 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. We don't just hand you a router and walk away; we run the connection as a managed, monitored service.
Your migration options
Rather than chase a like-for-like Cisco SKU, the smarter move for most Australian businesses is a currently-supported, security-patched managed router on connectivity that fits how you work:
- Managed business internet — a modern, supported router supplied, configured and monitored by us, so the device at the heart of your network is always current and patched.
- Business NBN or gigabit fibre — the right connection for your site, with the router matched to it instead of an end-of-life Cisco box bolted onto a new service.
- Internet failover — automatic 4G/5G backup so a single outage never takes the whole office offline, layered on top of your primary link.
A migration planned to avoid downtime
We plan the swap around your trading hours, pre-configure the new router, and cut you over cleanly so staff keep working. Your public-facing services and connections stay intact, and there are no numbers to lose on a data service. Replacing an old Cisco router is also the moment to stop overpaying: our bill reviews have identified savings of up to 65%.
One team for the internet and the phones on top
Because we also supply the phone system that rides over your connection, the whole stack is set up to work together and monitored 24/7 by one local team. If you're modernising the router, it's the natural time to look at the rest — whether that's SIP trunks or a move off a legacy phone system, covered in our legacy system replacement guide. No finger-pointing between providers when something needs a hand.
Real Connections. Real Easy. Send us a recent bill and we'll show you exactly what a clean move off your old Cisco router looks like — and what it saves.
Frequently asked questions
Is my Cisco 887 still safe to use in 2026?
It still routes traffic, but it no longer receives Cisco security patches — support ended on 29 April 2023 or 29 October 2023 depending on the 887 variant, and the Last Date of Support has passed. Any vulnerability discovered now will never be fixed on the device, which is why we recommend planning the move while you have choices.
Do I have to replace the router right now?
Not this minute, but don't leave it. The hardware is end-of-life and unpatched, so the safe approach is to plan a calm, scheduled swap rather than wait for a failure or a security incident. Talk to us and we'll assess your setup and give you a clear, no-pressure timeline.
What replaces a Cisco 880, 887 or C819?
Cisco's own migration path is the Catalyst/ISR 1000 and 900 series for the 880/887 branch, and rugged IR1101/IR1821 models for the hardened 819. For most Australian businesses, the better answer is a currently-supported, managed router on business NBN, fibre or 5G — supplied and monitored by us — rather than another box you maintain yourself.
Will changing the router disrupt my internet or phones?
Done properly, no. We pre-configure the new router and schedule the cutover around your hours, so the outage is brief and planned. Your services, connections and phone numbers carry across, and one local team owns the whole change from start to finish.
