I love call routing and scripting. With over 20 years experience I know how to make calls flow and how to create some pretty cool integrations with your CRM or any other app with an API. Five9 is the latest cloud phone system that I'm obsessed with. I've developed some out of the box IVR's and outbound drip campaigns that will increase your contact rate by 10% or more. Think of the Drips service but at no cost after implementation. Reach out with any questions you might have :)
