Keeping NEC Systems Running After Vendor Exit
If your NEC phone system supports critical teams or multiple sites, downtime isn’t just annoying — it stops work.
- NEC has exited the on-prem market.
- Parts are harder to source.
- Experienced NEC engineers are becoming scarce.
Most providers no longer support these systems. We still do.
Prosum engineers have supported hundreds of NEC systems across healthcare, enterprise and multi-site organisations. Our Melbourne-based team supports organisations across Australia — keeping these systems stable and running.

What our clients say about us
I’m very glad and fortunate that I had PROSUM looking after my IT and CCTV. They are trust worthy, reliable and very easy to work with.
Mina Zacharia,
MANAGER | ASTRO MEDICAL IMAGING
Very good and prompt service. Friendly staff.
Paul Bhatti,
WATSONIA VETERINARY CLINIC
I recently had a new VC installed from the team at Prosum. David Colletta and his team were not only professional with the installation, but at all times, the communication was second to none from them to see at each step where we were at. The installers were brilliant, and to top it off, they cleaned after the installation leaving us nothing to do. How refreshing this was. Again, I cannot speak highly enough of the team at Prosum; their professionalism was second to none, and their on-time approach was exactly that on time! Please do yourself a favour and get the team out there to look at what your needs are for the business, big or small. They have it all! Well done and thank you.

We needed an experienced ICT VoIP provider that could implement a new telephony solution without affecting existing telephony services and business operations. After reviewing other providers, we selected PROSUM who was able to successfully migrate all our users onto the new NEC platform and complete the project in a timely manner. PROSUM continue to provide support for our NEC Telephony and Contact Centre environment and I would recommend their services to other organisations and enterprises.
Andrew Trinh,
ICT INFRASTRUCTURE & SERVICE DELIVERY MANAGER - VICTORIAN CYTOLOGY SERVICE LIMITED
We are constantly looking to continuously improve the way we do business and service our customers and distributors within our customer service operations. This is why we selected PROSUM as our telephony and contact centre provider. Their experience means we have a VoIP provider we can rely on to provide and maintain our telephony and contact centre environment.

INFORMATION TECHNOLOGY MANAGER - STIHL
Aitken Real Estate had to move office and sought David Colletta of Prosum advice about switching our telephony to the cloud. Extremely helpful, no-nonsense information and can get the job done. Their tech Antoine was sensational. No delays, no problems. Highly recommend!
Stephen Aitken,
AITKEN REAL ESTATE
Thanks to the PROSUM team for the successful migration of the Brisbane phone system. A great deal of planning and hard work in the preparation resulted in a smooth migration with zero downtime to the business – a reflection on the dedication and preparedness to the project. Thank you.

FAQs about On-Premises Communications Platforms
Not usually. Many NEC systems continue running reliably for years with proper maintenance. We can assess your setup and let you know whether it makes sense to maintain or start planning an upgrade.
It depends on the model, age and condition. Systems like the SV9100, SV9300 and SV9500 can often be supported for years with parts and regular servicing. A quick phone call with our engineers can give you a clear idea of remaining lifespan.
Yes. Prosum has supported NEC systems for over 25 years. We provide local maintenance, repairs, parts replacement and system changes for businesses across Melbourne, Victoria and Australia-wide.
Yes. We support both current and older NEC models, including SV9100, SV9300 and SV9500. We can provide maintenance, repairs, replacement parts and advice on upgrades when the time is right — so you don’t have to replace your system before you need to.
If you’re on a Prosum maintenance contract, you get priority support and guaranteed response times: Critical issues: response within 30 minutes. All other issues: response within 2 hours. For non-contract customers, we’ll always help on a best-effort basis when our technicians are available, but contracted clients receive priority.
Either way, you’ll speak directly with our local Melbourne team and get help from technicians who know NEC systems inside out.

You can upgrade to a modern on-prem system like Alcatel or move to a cloud phone system such as NEC UNIVERGE BLUE or other hosted platforms. We’ll help you compare both and choose what suits your business. You get one local team who understands your business and keeps your phone system running smoothly long term.
In 10–15 minutes, we identify your model, check system health, flag any risks and recommend whether to maintain or upgrade. You’ll get clear next steps and practical advice — no obligation.
It depends on your needs. Cloud suits remote or growing teams and reduces on-site hardware. On-prem gives you full local control and can suit sites with stable infrastructure. We’ll explain the pros and cons for your situation.
