It's not even close. I was reluctant too for awhile- I would recommend Five 9: www.five9.com/Dialer. I run 2-3 lines per agent at any given time, our contact rates have skyrocketed. You can also setup Five 9 to automatically batch the data input into your CRM, so you don't have to keep two separate systems for lead notes. Our contact rate increased by about 60%, the only issue is every once in awhile a client will answer a call and I don't have anyone actually available to take it, but that can be fixed by running less lines at a time.
