Hi, I'm David Hopper, CEO of Auditmacs.com. Our experience with a managed Cisco Private IP VoIP solution went so well, our company became a solution provider to sell and distribute the product after we installed in house ourselves. We didn't make the conversion for cost savings however, but rather for feature functionality and efficiency issues. We researched VoIP for years prior to making the change. We can say from experience that all VoIP isn't created equal. The performance enhancements our organization has realized have been substantial. We experienced minor "tweaking" during the transition but zero outages. We exhausted extensive research on the project and would encourage anyone thinking about VoIP to contact us. We have done extensive research on it. 800.618.2575 www.auditmacs.com
