Network Requirements

To configure the network requirements for a Scout System with IDAS Multi-Site Trunking endpoints, consider the following:

  • UC-FR5000 network link.

    One ongoing call requires 13 – 17 kilobits per second (kbps).

  • IDAS allows a maximum jitter of 180 milliseconds (ms).

    If a delay of more than 180 ms occurs, audio begins to sound choppy. Scout allows jitter ranging from 60 ms to 2.5 seconds.

  • QoS (Quality of Service).

    VPGate supports Differentiated Services (DiffServ) values for IDAS audio and control packets, which are transmitted between VPGate and the IDAS endpoint using a single UDP connection. This allows VPGate to set a higher priority for VoIP packets to ensure audio is transmitted through the network without unnecessary delays.
