The best part of using ultracommms is their customer service team. They are always willing to help you out in any way they can, even if it's just giving you advice or suggestions. Sometimes I find myself calling them for a simple question, only to be told "I'm sorry we don't have an answer for that". This isn't something I would say about every provider, but this has been my experience with ultracommms. If you're looking for a reliable call center solution, look no further. I've used other providers in the past, but nothing comes close to the level of service and support provided by ultracommms. I am solving problems for our clients, not having to worry about the technical side of things.
