I have been using this phone system for a year now, so I have already accumulated some experience, I can objectively evaluate this service. During all this time, there were no unpleasant situations. A couple of times there were problems that were eliminated in a short time, the company's employees work quickly, and most importantly, stably. Without any failures. The company is reliable, everything suits me. I advise them to others.

Very friendly and professional technical support, always ready to help. At first I had some difficulties with their VoIP phone system, but these guys were super patient and explained me everything again and again when I contacted them. 10/10, strongly recommend this provider, my company is completely satisfied with Tre Group service

Our company managed to find a reliable and worthy operator. If any question arises, the managers respond instantly and provide highly qualified assistance. We like the great variety of services provided and the service, we tried different functions, especially we liked the digital investigation. Never had any problems with communication. Thank you, we were satisfied and will continue to cooperate!

This provider is the best operator I have ever worked with. I am happy with everything! I think the quality of the connection is perfect. The dial-up time is short. A clear and easy-to-use personal account. Payment by any method including those for legal entities. Balance notifications via SMS or email. Multichannel. In terms of price-quality ratio, this is the best option. I cannot assess the work of technical support, I have not had any problems.

We have been choosing a service provider for a long time, and we chose this company. We were attracted by the great variety of functions, we immediately connected a server audit and data protection. Communication is good, technical support is reliable, any question is solved instantly. We would like to purchase other additional features in the future. We like everything, thank you.

My business partner who is a very good friend of mine advised me this company as a reliable VoIP provider and great data protection service. After only 3 months of working with these professionals I can already confirm that everything I heard from my friend is 100% true. Now I am considering to connect network audit as well, because there is no doubt I can rely on Tre Group.

Our company has been working with this operator for more than a year. And now it is time to leave an honest reviews about their work. Here we were able to find uninterrupted communication, tools for the analysis of incoming and outgoing calls, as well as the server audit function, which we were looking for for a long time. It has all the necessary functionality. We use call recording and storage, a voice menu, we are completely satisfied.

For our company picked up all the necessary services, liked the network audit, previously not even heard of such a function, however, it is a godsend for any company. A large selection of numbers, all the calls are recorded, there is full control over the work process, which has a very positive effect on the quality of work and the development of the company. Thank you for your work.

We are the owners of a travel company, daily calls abroad were eating up a huge amount of money. I can say that we were pretty lucky to find this provider. Generally speaking, using VoIP is much more profitable than regular mobile phone service, but these guys turned out to have a lot of rates that helped us reduce our bills considerably.

This provider's prices are extremely reasonable and more favorable than any of their competitors, but the quality of service, the quality of communication is several times higher. For our company, it is surprising because the previous provider who provided communication services was absolutely not interested in meeting the customer or fixing problems. But now we are completely satisfied with the new service.

Great service at good prices. All communication tasks are closed without any problems. I am very pleased with the support, they always help to resolve any issues quickly.

I would like to thank the team for its high professionalism and responsible approach to solving the tasks set. I would like to note that during the cooperation the team has proved as a reliable partner. When providing services, employees show initiative, interest, and understanding of goals and objectives. Problems, if they occur, are eliminated promptly. We are conducting further cooperation and recommend this company as a responsible and reliable IT partner.

I have been using the TRE Group phone services for a couple of months now and I am completely satisfied with it. Fair prices and high quality of communication! Awesome tech support also, always ready to help!

The company's VoIP phone system services are at a high level. Especially suitable for calls to international destinations. It doesn't matter to me if I call Germany or Australia, the quality of communication will be the same. I would also like to mention the technical support, which solves any issue as quickly as possible.

We cooperated with different companies and none of the operators could fully cover our tasks. This provider promptly connected all our offices, set up the necessary functions for us, found a network audit, a very convenient function. Communication is decent, technical support is always in touch.

This is a good VOIP service, thanks to which, we have fully established work in our office. Easy integration with third-party services, which allows our managers to call requests directly from the interface. We connected server audit from additional functions, which allowed us to fully control the work process. We are 100% satisfied with the service.
