Big carriers treat business customers like account numbers. We don't. When you call SIP Connect you reach a real person in Greensborough who knows telco inside out — real humans, no robots, no offshore call centre — and who can have an engineer on site when something needs hands on it. Our team brings over 80 years of combined industry experience, and our customers rate us 5.0 on Google.
What we do
Business internet
business NBN, gigabit fibre and 5G fixed wireless, fully managed and monitored 24/7 with free WAN security built in.
Phone systems
3CX, hosted PBX and Microsoft Teams calling, plus clean NEC end-of-life migrations and Cisco support.
Voice and numbers
SIP trunks, business VoIP and 1300 and 1800 inbound numbers.
Vendor-neutral, so the advice is straight
We aren't tied to a single platform. We recommend the system that fits your team — 3CX, Microsoft Teams or a hosted PBX — and we'll tell you plainly when one is wrong for you. Because we also supply the internet underneath your phones, the whole setup is tuned to work together and supported by one local team, with one number to call.
Why businesses switch to us
Because we install fast — a new phone system live in days, not weeks. Because we save real money: a free bill analysis uncovers what you're overpaying, our bill reviews have identified savings of up to 65%. And because we stay accountable long after the install. We're not the cheapest self-serve box on the internet — we're the local team that sets it up properly, manages it for you, and answers when you call.

Frequently asked questions
Where is SIP Connect based?
Level 4, Suite 2, Greensborough Plaza, 25 Main St, Greensborough VIC 3088. Call us on 1300 747 266 (1300 SIPCONNECT), on 03 9018 9873, or email sales@sipconnect.com.au. We're proudly north-east Melbourne and we support businesses right across Australia.
What does vendor-neutral actually mean for me?
It means we don't have a product to protect, so we recommend what genuinely suits you. For most teams that's 3CX or a hosted PBX; if your people already live in Microsoft Teams, Direct Routing turns Teams into your phone system. We size it to how you work and your budget, then show you the numbers.
How quickly can you get us up and running?
A new phone system is usually live in days, not weeks: we design it, switch it on and train your staff. Moving your existing numbers takes longer. A standard port typically takes 5–10 business days and a complex port 2–6 weeks, so we set up a temporary call diversion and customers can keep reaching you while the port completes. See number porting for the detail.
Do you really pick up the phone, or is it a call centre?
You reach a real person in Greensborough every time — no offshore call centre, no robots. When something needs hands on it, we can put a local engineer on site.
