I like most of its features such as ability to dial out from multiple number at once time etc. It can handle more than 100 users simultaneously with ease if need be but it gets slow when there are too many people connected hence we have limited our callers sometimes till they disconnect their calls themselves which isn't good for business especially during peak hours! So far no major issues so i do recommend this product because you get what u pay! Its great solution considering your budget constraint compared oto other competitors who charge much higher rates even after giving them free trial periods/demo sessions!
