Fixed delays cannot be controlled as they are caused by the bodily distance the packets travel. They are especially problematic when satellite circuits are involved due to the lengthy distance to a geostationary satellite tv for pc and back; delays of 400–600 ms are typical. Latency could be minimized by marking voice packets as being delay-delicate with QoS methods similar to DiffServ. However, VoIP traffic to and from the on-premises systems can often also be despatched over safe personal hyperlinks. Examples include personal VPN, site-to-web site VPN, non-public networks similar to MPLS and SD-WAN, or via private SBCs .
