PeopleLink is a more flexible and scalable video conferencing solution compared to hardware-based solutions. It allows participants to join from any device through BYOD and licenses can be scaled up without needing new hardware. In contrast, hardware-based solutions require purchasing new equipment for each additional endpoint. PeopleLink also has lower capital and recurring costs since it doesn't require dedicated bandwidth or frequent hardware replacements. Its licenses are perpetual and come with remote support, while hardware solutions have shorter lifecycles and on-site support.
