Overview

Comms Group Limited is an ASX-listed communications business headquartered in Sydney. It sells cloud voice to Australian businesses and multinationals, including Microsoft Teams Calling, a hosted phone system and SIP platform, Cloud Connect for Webex Calling, inbound and toll-free numbers, contact centre and call recording add-ons, and wholesale voice. For Australian SMEs and corporates it also offers mobile services and connectivity such as fibre, nbn, SD-WAN and firewall services. It acquired Next Telecom in January 2021 and the business and assets of TasmaNet in June 2025. On 1 September 2026 it settled the sale of its IT managed services division, onPlatinum, to efex, saying it would focus on cloud communications, unified communications, domestic telecoms and global services.

Businesses review their phone provider for ordinary reasons: a contract is coming to an end, the office is moving, the phone system is due for a refresh, or they want their phones and internet from one carrier that runs its own network. Whatever the reason, it is worth comparing before you renew.

Summit offers Microsoft Teams Calling through Direct Routing, a cloud phone system, SIP trunks and 1300 and 1800 numbers, with business nbn, Ethernet over fibre and 4G backup alongside. Summit Internet is an independent carrier and is not affiliated with Comms Group.

How Summit Helps

  • Microsoft Teams Calling via Direct Routing

    If your staff make and take calls in Teams, Teams Calling connects Teams to the phone network through Direct Routing. You keep your existing Microsoft licensing arrangements, as Summit does not resell Microsoft licences.

  • A Cloud Phone System With Every Feature Included

    Hosted PBX starts from $10 per user per month and includes auto attendant, ring groups, call queues, voicemail to email, call recording and mobile and desktop apps. We can preconfigure your handsets and ship them to you.

  • SIP Trunks for the Phone System You Already Own

    Keeping your existing PBX? SIP trunks start from 2 channels and scale up or down as your call volumes change.

  • Inbound 1300 and 1800 Numbers

    Move your 1300 and 1800 numbers alongside your local lines, with fax to email and on-hold messaging available too.

  • A Licensed Carrier With Its Own Network

    Summit holds ACMA Carrier Licence #388 and has been connecting Australian businesses for 26 years. We build, own and operate our network, with Points of Presence in NEXTDC data centres and DDoS protection as standard.

  • Voice Prioritised on Summit Internet

    When your internet connection is also Summit's, voice traffic is prioritised with QoS. Business nbn includes a static IP, with speeds up to 2000/500 Mbps on full-fibre nbn, and Ethernet over fibre is available for sites that need dedicated capacity.

  • 4G Backup and Business Mobiles

    4G Backup fails over automatically to Australia's biggest mobile network, with 98.8% population coverage, and fails back when your main link returns. Add business mobile SIM plans to the same account.

  • One Bill

    Phones, internet and mobile from Summit arrive on one bill, with one carrier responsible for the lot.

How It Works

  1. 1 Tell us what you have

    Share a recent bill or a list of your Teams users, phone numbers, inbound numbers and sites, and when your current agreement ends.

  2. 2 Get a quote

    We recommend Teams Calling, Hosted PBX or SIP trunks to fit the way your staff work, and plan the timing around your contract.

  3. 3 Set up the new service

    We configure Direct Routing, your cloud phone system or your SIP trunks, with handsets preconfigured and shipped if you need them.

  4. 4 Port your numbers

    We lodge the port of your existing numbers. Keep your Comms Group service active until the port completes, because only active numbers can be ported.

  5. 5 Cut over and cancel

    Once your calls are live on Summit, you confirm the cancellation of any remaining services with your old provider.

Reliable phones and internet are essential for a busy practice like ours, and Summit has delivered exactly that.

  • 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 Comms Group?
No. Summit Internet is an independent Australian carrier holding ACMA Carrier Licence #388. We are not affiliated with Comms Group or any of its brands.
Why switch if my Comms Group service is working?
If your current services do everything you need, there may be no reason to switch. Businesses usually look around when a contract is ending, when they are moving office, when they want phones and internet from one carrier, or when they want to add services such as 4G backup.
Will I have to pay to break my contract?
That depends on your agreement with Comms Group. Check your contract for any minimum term or early termination charges. We can help you time the switch to your contract end so you are not paying twice.
Can I keep my phone numbers?
Yes, existing numbers can generally be ported to Summit, including 1300 and 1800 numbers. The ACMA says single local numbers generally port in 8 to 15 days, and ports involving multiple numbers can take up to 30 days. Keep your current service active until the port completes, because only active numbers can be ported.
Can Summit provide Microsoft Teams Calling?
Yes. Summit connects Microsoft Teams to the phone network using Direct Routing. Summit does not resell Microsoft licences, so you keep your licensing with your current Microsoft provider.
Can I keep my existing phone system?
Yes. If you own a phone system you want to keep, Summit's SIP trunks connect it to the phone network, starting from 2 channels and scaling up or down as you need.
Do I have to move my internet to Summit as well?
No. You can move just your phones. If you also move your internet, voice traffic is prioritised with QoS and everything arrives on one bill.
Does Summit work with businesses outside Melbourne?
Yes. Summit's voice services, business nbn, 4G backup and mobile plans are available to Australian businesses nationally. Fixed wireless is available in Melbourne and regional Victoria only.
