The next important topic to consider is the company's network performance. Whether Lync deployed on physical or virtual servers affects the overall network performance. As mentioned earlier, the Lync Server is responsible for real-time communications so it requires a fast and efficient network. If a data packet is delayed by just a few milliseconds, it would appear to the users as an audio glitch, a voice delay, or a frozen video.
