Excellent VOIP telephony with great flexibility for our small office & work from home seemlessly.
Amazing customer service on the rare occasion you need it.
Great to deal with real people. I needed another extension/line, phoned them (hotline for existing customers) and collected a new fully configured desk phone in Maynooth 30 mins later. Plug into network and its up and running. Couldn't be simpler or quicker. So glad I ditched my previous provider.

"Very easy to deal with"
Having used NUACOM in previous employment and found it very good, when I setup my own company I choose NUACOM for my own phones, when one of my customers needed to change Telecoms company I immediately suggested NUACOM also.
Their interface is intuitive and support is great.

"Highly Recommend"
After our last company decided to leave the market, I began my search for a replacement. Nuacom was my first call and after speaking with the agent there was no hesitation is moving forward and confirming my order. Evey detail I needed was explained and within 15 minutes my process was underway. The customer service and support is excellent. I opted for the new phones from Nuacom and they are excellent quality. I now have a better service and more features than before at much better prices.
Shayne K4 June 2024
Nuacom were extremely quick in setting up our account, delivering our new phones, arranging training and everything else that comes with integrating a new phone system. I have found it all such an easy process, their customer support has been very helpful and I would be very happy to recommend their service.

Frequently asked questions
What Is VoIP?
Voice over Internet Protocol (VoIP) is a technology that enables voice communication over the internet instead of traditional phone lines. With VoIP, analog audio signals are converted into digital data packets and transmitted over internet networks. This allows for cost-effective and efficient voice communication, often providing features like video calls, conferencing, and instant messaging. VoIP services can be accessed through dedicated VoIP phones, computers, or mobile devices. By leveraging the internet, VoIP eliminates the need for traditional telephone infrastructure, offering businesses and individuals a flexible, scalable, and often more affordable solution for voice communication.
What is a "Cloud-based" service?
Our service is “cloud-based” which means that the core processing equipment and software are located in different data-centres. Many popular and established brands such as Amazon, Google, Salesforce, Microsoft, etc. offer cloud-based systems, because they are more secure, flexible and cost-efficient.
Why should I switch to cloud telephony?
Traditional phone systems are becoming obsolete and limited: it requires additional hardware/support, it involves additional charges for line rental and is based on old technology. With a cloud-based phone system, you only need an Internet connection to manage your business communication. You get very low call rates, free national calls, local or international phone numbers, tons of advanced VoIP features (call queues, voicemail, call transfer, call conference, IVR menu, call recording, etc.), professional 24/7 support and so much more.
Will I have a good call quality?
Actually, your call quality will be better and clearer than on traditional phones. This is because all the calls made via our system using digital wideband audio, which provides a superior call quality.
Can I keep my existing phone number?
Yes, you can keep your existing phone number (by porting it to us). It usually takes from 2 to 10 days to port your number. Please note that there is once-off charge associated with each number porting.
