I was also particularly impressed by the quality of the installation and the initial support to ensure that everything was set up perfectly. I would thoroughly recommend them and I have no doubt we will be using them again in the future as our business continues to expand.”

St. Andrews Catholic School

“Having decided to upgrade our telephone systems, we had contacted three companies, each of which had presented us with their proposals. Whist in the process of trying to evaluate which system would be most suitable, one of our supplied recommended T2K. we decided to contact T2K and arrangements were made for them to come and see us. Unlike the previous three companies, we found ourselves being introduced to an extremely versatile system by someone with a great deal of experience, a practical background in telecommunications, and what’s more, someone who explained the technicalities of what he was able to offer in an easy to understand formal, all of which inspired confidence. Having made sure that the system was capable of doing what we needed and more, as well as being satisfied that it was competitively priced, we paced our order with T2K. Installation to place exactly as arranged, with the minimum disruption, and the after sales service has been brilliant.”

They really came through with a cost effective and highly functional system. Implementation happened seamlessly and they configured it to our requirements. On-going support has been good and they have adapted the system to our changing needs. All in all, we believed they would be difficult to beat for any business dependant on their telephony.”
