I have been using this product for about 5 years now, i've never had any issues with it or noticed anything that wasn't great while working in its use to help me do my job better every day! If you are looking at an all-inclusive solution go ahead & try out mxie first before purchasing other products/services from them (esp if their prices seem too high). Our team has benefited greatly by being able to quickly create lists of people who we need access information off of our phone system. Helps us manage call traffic so no one gets confused when there's more than 1 person wanting info during busy times.
