Overview

Interphone is a Perth telecommunications provider based in Osborne Park, Western Australia. It sells fibre internet over its own GPON fibre network, along with fixed wireless and nbn connections, and voice services including SIP and Hosted Voice. For larger businesses it offers WAN links between sites, multisite voice and data packages and internet transit, and it also serves apartment and lifestyle village developments.

Businesses review their phone provider for plenty of reasons: a contract is ending, the team is moving office or opening a site in another state, or they want their phones and the connection those phones depend on to come from one carrier that deals only with businesses.

Summit offers a cloud phone system, SIP trunks and Microsoft Teams Calling, plus business nbn with a static IP, Ethernet over fibre, 4G backup and business mobiles, all on a network we build, own and operate. Summit Internet is an independent carrier and is not affiliated with Interphone.

How Summit Helps

  • A Business-Only Carrier

    Summit does not sell residential services. Every product, plan and support process is built around what businesses need, and we have been doing it for 26 years.

  • Hosted Voice With Every Feature Included

    If you use a hosted phone system today, Hosted PBX starts from $10 per user per month and includes auto attendant and IVR, ring groups, call queues, voicemail to email, call recording and mobile and desktop apps. Every feature is included, so there are no add-ons to work out per user.

  • SIP Trunks for the Phone System You Already Own

    If your business runs its own PBX on Interphone SIP, Summit SIP trunks start from 2 channels and scale up or down as your call volumes change, so you can keep the system your staff already know.

  • Handsets Ready to Plug In

    Moving to Hosted PBX? We can preconfigure the handsets and ship them to you, so they work as soon as they are plugged in.

  • Microsoft Teams Calling

    If your team lives in Teams, Teams Calling connects it to the phone network through Direct Routing, so staff make and take calls on their business numbers from Teams. You keep buying your Microsoft licences as you do now.

  • Business Internet Across Australia

    Business nbn comes with a static IP included, with speeds up to 2000/500 Mbps on full-fibre nbn, and Ethernet over fibre is available for sites that need a dedicated service. When your connection is also Summit's, voice traffic is prioritised with QoS. Our network has Points of Presence in NEXTDC data centres with DDoS protection as standard.

  • 4G Backup for When the Line Drops

    4G Backup fails over automatically to Australia's biggest mobile network, with 98.8% population coverage, and fails back automatically when your main service returns.

  • Inbound Numbers, Mobiles and One Bill

    Add 1300 and 1800 numbers, fax to email, on-hold messaging and business mobile SIM plans. Internet, phones and mobile arrive on one bill.

How It Works

  1. 1 Tell us what you have today

    List your Interphone numbers, whether you use SIP or Hosted Voice, your handsets or PBX, the internet services at each site and when your agreement ends.

  2. 2 Get a quote

    We recommend the right setup, whether Hosted PBX, SIP trunks or Teams Calling, plus internet and backup if you want them, and send you a written quote.

  3. 3 Set up your phone system

    We build your auto attendant, ring groups and queues to match how your team works, or configure SIP trunks for your existing PBX, and preconfigure and ship handsets if you need them.

  4. 4 Port your numbers

    We port your existing numbers across. Keep your Interphone service active until the port completes, because only active numbers can be ported. The ACMA says single local numbers generally port in 8 to 15 days, and multi-number ports can take up to 30 days.

  5. 5 Cancel once you are live

    When your numbers have moved and calls are working, you cancel the old service.

  • 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. Highly recommend Summit to any business looking for reliable service and great customer support.Read more

  • 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

Frequently asked questions

Is Summit Internet part of Interphone?
No. Summit Internet is an independent Australian carrier holding ACMA Carrier Licence #388. We are not affiliated with Interphone, and this page is not endorsed by Interphone.
Why switch if my Interphone service is working?
If Interphone does everything you need, there may be no reason to switch. Businesses usually talk to us when a contract is ending, when they are moving office or adding sites, or when they want their phone system, internet and mobiles from one business-only carrier.
Can I keep my phone numbers?
Yes. We port your existing numbers to Summit. Keep your Interphone service active until the port completes, because only active numbers can be ported. The ACMA says single local numbers generally port in 8 to 15 days, and multi-number ports can take up to 30 days.
Will I have to pay to break my contract?
That depends on your agreement with Interphone. Check your terms, and if there is a minimum term, we can plan the switch so your Summit service is ready when it ends.
I use Interphone SIP with my own phone system. Can I keep it?
In most cases, yes. Summit SIP trunks work with existing phone systems, start from 2 channels and scale up or down. Tell us the make and model of your system and we will confirm before you switch.
Do I need to change my internet provider too?
No. Our phone services work over your existing connection. If you would like your internet with us as well, voice traffic is prioritised with QoS when the connection is also Summit's, and you get one bill for internet, phones and mobile.
What internet can Summit provide in Perth?
Business nbn is available nationally with a static IP included, and Ethernet over fibre suits sites that need a dedicated service. Availability depends on your address, so we check it as part of your quote. Summit's fixed wireless network covers Melbourne and regional Victoria only.
Can I keep my 1300 or 1800 number?
Yes. We provide 1300 and 1800 inbound numbers, and existing inbound numbers can be ported across in the same way as your other numbers.
What happens if my internet goes down?
Add 4G Backup. It fails over automatically to Australia's biggest mobile network, with 98.8% population coverage, and fails back automatically when your main connection returns.
