For businesses looking to bring in a great unified communications solution, Microsoft Lync can be a great way to go. Kevin Kieller, a professional in the industry, said on NoJitter.com that businesses have to understand that Lync is a complete UC solution and more than simply something to replace a voice system.
"Yes, Lync can, does, and for many organizations should, replace their existing voice system," he wrote. "However, if you are only looking for a voice system, Lync may not be the best choice. Lync is a UC solution and unified communications is about much more than just voice. While Lync is not only a voice system, I think it is important to emphasize that if you choose, you can deploy IP phones with Lync, just like you can with any other 'voice only' solution."
