We've worked with Converged for years now - most recently on a very large Avaya upgrade of our entire phone system including a change to our carrier. It was a large undertaking and they were outstanding. It started with an excellent outlining of what needed to happen and when, along with an accurate estimate of price, and then expertly managed by Tom - which was not easy considering how many moving parts and different companies there were involved. Project finished on time. I see a long working relationship ahead for us for years to come.

I was seeking a new phone system and found Converged Communications Systems. I had a great experience with everyone there I was in contact and the transition was seamless. Their technicians are very knowledgeable and quick to respond. Highly recommend for UC services.

Converged Communications Systems has been a vendor of Lawrence Hall for a number of years. They have installed and supported phone systems at a number of our locations. They have done some IT consulting work for us as well. They are very professional, and extremely responsive. They are not a hard sell / leave you in the weeds afterwards company. at all. Our rep, Joe Williams is great to work with. Joe has deep knowledge of the industry and is incredibly trustworthy.

Great experience explaining the available business phone options to us and helping us settle on RingCentral to migrate our entire team away from our previous system. Go to these guys, they know their stuff!
