Overview

Lightwire is a telecommunications provider headquartered in Hamilton, New Zealand, that sells to businesses in New Zealand and Australia. Its business range covers business broadband and managed network and SD-WAN services, along with voice products including 3CX unified communications, Microsoft Teams Calling and SIP trunks. In February 2025 Lightwire Business acquired Ufone, an Auckland-based VoIP, 3CX phone and contact centre provider.

Businesses review their connectivity for ordinary reasons: a contract is coming to an end, the office is moving, or they want internet and phones from one carrier instead of several suppliers.

Summit Internet supplies business nbn with a static IP included, Ethernet over fibre, 4G Backup and business phone systems, delivered over a network we build, own and operate, with Points of Presence in NEXTDC data centres.

Summit Internet is an independent carrier and is not affiliated with Lightwire.

How Summit Helps

  • Business nbn with a static IP included

    Our business nbn plans are available nationally and include a static IP at no extra charge, with speeds up to 2000/500 Mbps on full-fibre nbn. It suits offices running VPNs, remote access or hosted applications.

  • Ethernet over fibre for sites that need more

    Where a standard nbn service is not the right fit, Summit also supplies Ethernet over fibre.

  • Our own network, with NEXTDC Points of Presence

    Summit builds, owns and operates its network, with Points of Presence in NEXTDC data centres.

  • DDoS protection as standard

    Every Summit connection includes DDoS protection. You do not need to buy it as an add-on.

  • 4G Backup that switches over automatically

    4G Backup fails over to Australia's biggest mobile network (98.8% population coverage) if your main link drops, then fails back automatically when it returns.

  • Fixed wireless in Melbourne and regional Victoria

    For Melbourne and regional Victorian sites, Summit fixed wireless offers symmetric speeds from 10 Mbps up to 10 Gbps across 500+ suburbs, installed in 10 business days or the first month is free.

  • SIP trunks, Teams Calling or a Hosted PBX

    If you use SIP trunks or Teams Calling today, Summit offers SIP trunks from 2 channels and Microsoft Teams Calling via Direct Routing. Prefer a cloud phone system? Our Hosted PBX starts from $10 per user per month with every feature included. Voice traffic is prioritised when the internet connection is also Summit's.

  • One bill for internet, phones and mobile

    Internet, phones and business mobile SIM plans all come on one Summit bill, with one carrier to call.

How It Works

  1. 1 Tell us what you have

    List your current Lightwire services in Australia, your site addresses and contract end dates.

  2. 2 Get a recommendation and quote

    We match each site to business nbn, Ethernet over fibre or, in Melbourne and regional Victoria, fixed wireless, and add 4G Backup and phones where they make sense.

  3. 3 Schedule the install

    We time the new connection to suit your contract end date or office move, so the change lines up with your plans.

  4. 4 Cut over

    Your new service is installed before you switch traffic across. If you are also moving phones, numbers are ported while the old service stays active, because only active numbers can be ported.

  5. 5 Cancel the old service

    Once everything is running on Summit, you cancel the services you no longer need with your previous provider.

  • We recently moved our dental practice over to Summit for phone services, and the experience has been excellent from start to finish. The team has been responsive, professional, and incredibly helpful throughout the entire setup process. The transition was smooth, any issues were addressed promptly, and communication was always clear and efficient. Reliable phones and internet are essential for a busy practice like ours, and Summit has delivered exactly that. A special thank you to Michael for his patience and ongoing assistance during the transition.

  • After working with another ISP for several months to deliver a critical internet service for a major international sporting event, we were ultimately advised that the required upgrade was unlikely to be completed prior to event week. This left us facing a significant risk to service delivery. After exhausting all other options (and a few sleepless nights) we came across Summit Internet. From the initial conversation, Allan immediately understood the severity of the situation and quickly engaged his technical delivery team. Michael “Radar” was on site within days to assess and finalise a solution. Despite challenging conditions, including large trees and other obstructions, he worked tirelessly to design and implement an alternative approach. Leveraging an adjacent building, a temporary NBN connection, and a wireless link into the comms room, the solution was delivered within 24 hours of the initial site visit. Not only was the outcome faster than expected, but it was also more cost effective and delivered higher speeds than originally promised by the previous ISP. Over the course of the event, the service handled terabytes of data and supported hundreds of concurrent users without a single speed or performance issue. I cannot thank Summit Internet, particularly Allan and Radar enough for their exceptional service, technical expertise, and commitment to delivering under pressure. Highly recommended.Read more

  • Summit internet recently set my small business up with a local land line number and a soft phone that runs off an app on my mobile - getting my personal phone number off the internet and being able to distinguish between business and personal calls is a game changer. Whole process took less than a week, and is super cost effective. Highly recommend.Read more

No. Summit Internet is an independent Australian carrier holding ACMA Carrier Licence #388. We are not affiliated with Lightwire or Ufone.
Why switch if my Lightwire service is working?
If your current service does everything you need, there may be no reason to switch. Businesses usually review their provider at contract end, when moving office, or when they want internet and phones from one business-only carrier.
Will I have to pay to break my contract?
That depends on your agreement with your current provider. Check your contract end date and any early termination terms, and we can time the switch to line up with the end of your contract.
What internet options does Summit offer?
Business nbn nationally with a static IP included, Ethernet over fibre, 4G Static IP and 4G Backup. In Melbourne and regional Victoria we also offer fixed wireless with symmetric speeds from 10 Mbps up to 10 Gbps. You can check coverage here.

Yes. Summit offers a Hosted PBX, SIP trunks for existing phone systems, Microsoft Teams Calling via Direct Routing and 1300 and 1800 numbers.
Can I keep my Australian phone numbers?

Does Summit resell Microsoft licences?
No. Summit connects Microsoft Teams to the phone network via Direct Routing. Your Microsoft licences stay with your existing Microsoft supplier.
