At a consumer level, Skype uses the same technology as Vantact—VoIP.
Skype and Google Voice are simple VoIP solutions that allow free messages and calls over the internet meant for personal use.
In contrast, Vantact is a complete business communications solution. It covers phone calls, email, SMS, call recording, analytics, CRM, and more.
Vantact also has a dedicated support team and business features to improve productivity and lower costs.
