    Setting Description

    Preferred Speed for Placed Calls

    Determines the IP call speed your system uses when either of the following occurs:
    • A user sets the call speed to Auto on the Place a Call screen.
    • A user places a call from the directory.

    If the far-site system doesn’t support the selected speed, the system automatically negotiates a lower speed.

    The system doesn’t receive calls at a higher rate than the speed you set here.
