Zultys provides a more cost effective and reliable alternative to hosted phone systems. Some key advantages of Zultys include: 1) Lower upfront and ongoing costs compared to typical hosted systems which require purchasing equipment upfront and have higher monthly fees. 2) Superior call quality and reliability by leveraging existing internet infrastructure rather than relying on public internet connections prone to latency issues. 3) Local support provided by resellers to quickly address any issues versus remote call centers for hosted providers.
