Easy to use, efficient service provider with great customer support! They are always willing to help you whenever there is an issue or question that arises during your project implementation phase; they're also very knowledgeable about their products in general which can be helpful for those who don't have specific technical knowledge like me regarding VoIP networks/services (I'm pretty much self-taught). I've been using them since 2014 when we implemented our first nationwide call center at one point only serving calls from Canada but now serves all 50 states as well as international countries such as India and Mexico. It's definitely worth it because not having issues while implementing new centers has saved us tons of time & money over the years by avoiding downtime caused due to network problems / infrastructure failure etc., plus being able to serve customers 24 hours per day 7 days week without any interruptions makes everything easier overall even though some people might think otherwise if this were possible.
